ffmpeg-go

Go bindings for the FFmpeg AV libraries.

Features

Static build (does still require some system libraries, such as m).
Linux (arm64, amd64) and macOS (arm64, amd64) support.
Auto generated.
Thin layer over the C API.
Doc comments retained (where supported by clang).
GPL version of FFmpeg (allows for x264 etc).

TODO

Expose more headers.
Ensure acceleration enabled in builds.
Expose platform specific headers.
Cleanup internal packages.

Setup

go get github.com/csnewman/ffmpeg-go

Example

(The asciiplayer demo playing Big Buck Bunny, with some GIF artifacts)

The examples directory contains some ported and some custom examples based on the C docs.

An example of printing a file's metadata:

package main

import (
	"log"
	"log/slog"
	"os"

	"github.com/csnewman/ffmpeg-go"
)

func main() {
	slog.Info("Metadata")

	var ctx *ffmpeg.AVFormatContext

	url := ffmpeg.ToCStr(os.Args[1])
	defer url.Free()

	_, err := ffmpeg.AVFormatOpenInput(&ctx, url, nil, nil)
	if err != nil {
		log.Panicln(err)
	}

	defer ffmpeg.AVFormatFreeContext(ctx)

	if _, err := ffmpeg.AVFormatFindStreamInfo(ctx, nil); err != nil {
		log.Panicln(err)
	}

	ffmpeg.AVDumpFormat(ctx, 0, url, 0)

	streams := ctx.Streams()

	for i := uintptr(0); i < uintptr(ctx.NbStreams()); i++ {
		s := streams.Get(i)

		slog.Info("  Stream", "i", i, "id", s.Id(), "dur", s.Duration())

		meta := s.Metadata()

		var entry *ffmpeg.AVDictionaryEntry

		for {
			entry = ffmpeg.AVDictGet(meta, ffmpeg.GlobalCStr(""), entry, ffmpeg.AVDictIgnoreSuffix)
			if entry == nil {
				break
			}

			slog.Info("    Meta", "key", entry.Key(), "value", entry.Value())
		}
	}
}

FAQ

Q: Why is FFmpeg statically bundled?
- A: The version of FFmpeg varies by platform, making a one-size fits all style binding difficult with the Go build system and its lack of a build.go file.
Q: Why are the arm packages not built by CI?
- A: Ideally they would be. However, the free GitHub plan does not include arm builders.
Q: Why is library xyz not enabled?
- A: Libraries have been added on a as-needed basis. Feel free to create a PR enabling any additional libraries.
Q: I have some C code that I can't convert to Go, due to a missing binding feature
- A: Create an issue with a C sample, and we can go from there.

Functions ¶

func AVAddIndexEntry ¶

func AVAddIndexEntry(st *AVStream, pos int64, timestamp int64, size int, distance int, flags int) (int, error)

AVAddIndexEntry wraps av_add_index_entry.

Add an index entry into a sorted list. Update the entry if the list
already contains it.

@param timestamp timestamp in the time base of the given stream

func AVAddStable ¶

func AVAddStable(tsTb *AVRational, ts int64, incTb *AVRational, inc int64) int64

AVAddStable wraps av_add_stable.

Add a value to a timestamp.

This function guarantees that when the same value is repeatly added that
no accumulation of rounding errors occurs.

@param[in] ts     Input timestamp
@param[in] ts_tb  Input timestamp time base
@param[in] inc    Value to be added
@param[in] inc_tb Time base of `inc`

func AVAppendPacket ¶

func AVAppendPacket(s *AVIOContext, pkt *AVPacket, size int) (int, error)

AVAppendPacket wraps av_append_packet.

Read data and append it to the current content of the AVPacket.
If pkt->size is 0 this is identical to av_get_packet.
Note that this uses av_grow_packet and thus involves a realloc
which is inefficient. Thus this function should only be used
when there is no reasonable way to know (an upper bound of)
the final size.

@param s    associated IO context
@param pkt packet
@param size amount of data to read
@return >0 (read size) if OK, AVERROR_xxx otherwise, previous data
        will not be lost even if an error occurs.

func AVBesselI0 ¶ added in v0.2.0

func AVBesselI0(x float64) float64

AVBesselI0 wraps av_bessel_i0.

0th order modified bessel function of the first kind.

func AVBprintChannelLayout ¶

func AVBprintChannelLayout(bp *AVBPrint, nbChannels int, channelLayout uint64)

AVBprintChannelLayout wraps av_bprint_channel_layout.

Append a description of a channel layout to a bprint buffer.
@deprecated use av_channel_layout_describe()

func AVBufferDefaultFree ¶

func AVBufferDefaultFree(opaque unsafe.Pointer, data unsafe.Pointer)

AVBufferDefaultFree wraps av_buffer_default_free.

Default free callback, which calls av_free() on the buffer data.
This function is meant to be passed to av_buffer_create(), not called
directly.

func AVBufferGetOpaque ¶

func AVBufferGetOpaque(buf *AVBufferRef) unsafe.Pointer

AVBufferGetOpaque wraps av_buffer_get_opaque.

@return the opaque parameter set by av_buffer_create.

func AVBufferGetRefCount ¶

func AVBufferGetRefCount(buf *AVBufferRef) (int, error)

AVBufferGetRefCount wraps av_buffer_get_ref_count.

func AVBufferIsWritable ¶

func AVBufferIsWritable(buf *AVBufferRef) (int, error)

AVBufferIsWritable wraps av_buffer_is_writable.

@return 1 if the caller may write to the data referred to by buf (which is
true if and only if buf is the only reference to the underlying AVBuffer).
Return 0 otherwise.
A positive answer is valid until av_buffer_ref() is called on buf.

func AVBufferMakeWritable ¶

func AVBufferMakeWritable(buf **AVBufferRef) (int, error)

AVBufferMakeWritable wraps av_buffer_make_writable.

Create a writable reference from a given buffer reference, avoiding data copy
if possible.

@param buf buffer reference to make writable. On success, buf is either left
           untouched, or it is unreferenced and a new writable AVBufferRef is
           written in its place. On failure, buf is left untouched.
@return 0 on success, a negative AVERROR on failure.

func AVBufferPoolBufferGetOpaque ¶

func AVBufferPoolBufferGetOpaque(ref *AVBufferRef) unsafe.Pointer

AVBufferPoolBufferGetOpaque wraps av_buffer_pool_buffer_get_opaque.

Query the original opaque parameter of an allocated buffer in the pool.

@param ref a buffer reference to a buffer returned by av_buffer_pool_get.
@return the opaque parameter set by the buffer allocator function of the
        buffer pool.

@note the opaque parameter of ref is used by the buffer pool implementation,
therefore you have to use this function to access the original opaque
parameter of an allocated buffer.

func AVBufferPoolUninit ¶

func AVBufferPoolUninit(pool **AVBufferPool)

AVBufferPoolUninit wraps av_buffer_pool_uninit.

Mark the pool as being available for freeing. It will actually be freed only
once all the allocated buffers associated with the pool are released. Thus it
is safe to call this function while some of the allocated buffers are still
in use.

@param pool pointer to the pool to be freed. It will be set to NULL.

func AVBufferRealloc ¶

func AVBufferRealloc(buf **AVBufferRef, size uint64) (int, error)

AVBufferRealloc wraps av_buffer_realloc.

Reallocate a given buffer.

@param buf  a buffer reference to reallocate. On success, buf will be
            unreferenced and a new reference with the required size will be
            written in its place. On failure buf will be left untouched. *buf
            may be NULL, then a new buffer is allocated.
@param size required new buffer size.
@return 0 on success, a negative AVERROR on failure.

@note the buffer is actually reallocated with av_realloc() only if it was
initially allocated through av_buffer_realloc(NULL) and there is only one
reference to it (i.e. the one passed to this function). In all other cases
a new buffer is allocated and the data is copied.

func AVBufferReplace ¶

func AVBufferReplace(dst **AVBufferRef, src *AVBufferRef) (int, error)

AVBufferReplace wraps av_buffer_replace.

Ensure dst refers to the same data as src.

When *dst is already equivalent to src, do nothing. Otherwise unreference dst
and replace it with a new reference to src.

@param dst Pointer to either a valid buffer reference or NULL. On success,
           this will point to a buffer reference equivalent to src. On
           failure, dst will be left untouched.
@param src A buffer reference to replace dst with. May be NULL, then this
           function is equivalent to av_buffer_unref(dst).
@return 0 on success
        AVERROR(ENOMEM) on memory allocation failure.

func AVBufferUnref ¶

func AVBufferUnref(buf **AVBufferRef)

AVBufferUnref wraps av_buffer_unref.

Free a given reference and automatically free the buffer if there are no more
references to it.

@param buf the reference to be freed. The pointer is set to NULL on return.

@param ctx pointer to a context of a buffersink or abuffersink AVFilter.
@param frame pointer to an allocated frame that will be filled with data.
             The data must be freed using av_frame_unref() / av_frame_free()

@return
        - >= 0 if a frame was successfully returned.
        - AVERROR(EAGAIN) if no frames are available at this point; more
          input frames must be added to the filtergraph to get more output.
        - AVERROR_EOF if there will be no more output frames on this sink.
        - A different negative AVERROR code in other failure cases.

func AVBuffersinkGetFrameFlags ¶

func AVBuffersinkGetFrameFlags(ctx *AVFilterContext, frame *AVFrame, flags int) (int, error)

AVBuffersinkGetFrameFlags wraps av_buffersink_get_frame_flags.

Get a frame with filtered data from sink and put it in frame.

@param ctx    pointer to a buffersink or abuffersink filter context.
@param frame  pointer to an allocated frame that will be filled with data.
              The data must be freed using av_frame_unref() / av_frame_free()
@param flags  a combination of AV_BUFFERSINK_FLAG_* flags

AVBuffersinkGetSampleRate wraps av_buffersink_get_sample_rate.

func AVBuffersinkGetSamples ¶

func AVBuffersinkGetSamples(ctx *AVFilterContext, frame *AVFrame, nbSamples int) (int, error)

AVBuffersinkGetSamples wraps av_buffersink_get_samples.

Same as av_buffersink_get_frame(), but with the ability to specify the number
of samples read. This function is less efficient than
av_buffersink_get_frame(), because it copies the data around.

@param ctx pointer to a context of the abuffersink AVFilter.
@param frame pointer to an allocated frame that will be filled with data.
             The data must be freed using av_frame_unref() / av_frame_free()
             frame will contain exactly nb_samples audio samples, except at
             the end of stream, when it can contain less than nb_samples.

@return The return codes have the same meaning as for
        av_buffersink_get_frame().

@warning do not mix this function with av_buffersink_get_frame(). Use only one or
the other with a single sink, not both.

AVBuffersinkSetFrameSize wraps av_buffersink_set_frame_size.

Set the frame size for an audio buffer sink.

All calls to av_buffersink_get_buffer_ref will return a buffer with
exactly the specified number of samples, or AVERROR(EAGAIN) if there is
not enough. The last buffer at EOF will be padded with 0.

func AVBuffersrcAddFrame ¶

func AVBuffersrcAddFrame(ctx *AVFilterContext, frame *AVFrame) (int, error)

AVBuffersrcAddFrame wraps av_buffersrc_add_frame.

Add a frame to the buffer source.

@param ctx   an instance of the buffersrc filter
@param frame frame to be added. If the frame is reference counted, this
function will take ownership of the reference(s) and reset the frame.
Otherwise the frame data will be copied. If this function returns an error,
the input frame is not touched.

@return 0 on success, a negative AVERROR on error.

@note the difference between this function and av_buffersrc_write_frame() is
that av_buffersrc_write_frame() creates a new reference to the input frame,
while this function takes ownership of the reference passed to it.

This function is equivalent to av_buffersrc_add_frame_flags() without the
AV_BUFFERSRC_FLAG_KEEP_REF flag.

func AVBuffersrcAddFrameFlags ¶

func AVBuffersrcAddFrameFlags(bufferSrc *AVFilterContext, frame *AVFrame, flags int) (int, error)

AVBuffersrcAddFrameFlags wraps av_buffersrc_add_frame_flags.

Add a frame to the buffer source.

By default, if the frame is reference-counted, this function will take
ownership of the reference(s) and reset the frame. This can be controlled
using the flags.

If this function returns an error, the input frame is not touched.

@param buffer_src  pointer to a buffer source context
@param frame       a frame, or NULL to mark EOF
@param flags       a combination of AV_BUFFERSRC_FLAG_*
@return            >= 0 in case of success, a negative AVERROR code
                   in case of failure

func AVBuffersrcClose ¶

func AVBuffersrcClose(ctx *AVFilterContext, pts int64, flags uint) (int, error)

AVBuffersrcClose wraps av_buffersrc_close.

Close the buffer source after EOF.

This is similar to passing NULL to av_buffersrc_add_frame_flags()
except it takes the timestamp of the EOF, i.e. the timestamp of the end
of the last frame.

func AVBuffersrcGetNbFailedRequests ¶

func AVBuffersrcGetNbFailedRequests(bufferSrc *AVFilterContext) uint

AVBuffersrcGetNbFailedRequests wraps av_buffersrc_get_nb_failed_requests.

Get the number of failed requests.

A failed request is when the request_frame method is called while no
frame is present in the buffer.
The number is reset when a frame is added.

func AVBuffersrcParametersSet ¶

func AVBuffersrcParametersSet(ctx *AVFilterContext, param *AVBufferSrcParameters) (int, error)

AVBuffersrcParametersSet wraps av_buffersrc_parameters_set.

Initialize the buffersrc or abuffersrc filter with the provided parameters.
This function may be called multiple times, the later calls override the
previous ones. Some of the parameters may also be set through AVOptions, then
whatever method is used last takes precedence.

@param ctx an instance of the buffersrc or abuffersrc filter
@param param the stream parameters. The frames later passed to this filter
             must conform to those parameters. All the allocated fields in
             param remain owned by the caller, libavfilter will make internal
             copies or references when necessary.
@return 0 on success, a negative AVERROR code on failure.

func AVBuffersrcWriteFrame ¶

func AVBuffersrcWriteFrame(ctx *AVFilterContext, frame *AVFrame) (int, error)

AVBuffersrcWriteFrame wraps av_buffersrc_write_frame.

Add a frame to the buffer source.

@param ctx   an instance of the buffersrc filter
@param frame frame to be added. If the frame is reference counted, this
function will make a new reference to it. Otherwise the frame data will be
copied.

@return 0 on success, a negative AVERROR on error

This function is equivalent to av_buffersrc_add_frame_flags() with the
AV_BUFFERSRC_FLAG_KEEP_REF flag.

func AVCalloc ¶

func AVCalloc(nmemb uint64, size uint64) unsafe.Pointer

AVCalloc wraps av_calloc.

Allocate a memory block for an array with av_mallocz().

The allocated memory will have size `size * nmemb` bytes.

@param nmemb Number of elements
@param size  Size of the single element
@return Pointer to the allocated block, or `NULL` if the block cannot
        be allocated

@see av_mallocz()
@see av_malloc_array()

func AVChannelDescription ¶

func AVChannelDescription(buf *CStr, bufSize uint64, channel AVChannel) (int, error)

Get a human readable string describing a given channel.

@param buf pre-allocated buffer where to put the generated string
@param buf_size size in bytes of the buffer.
@param channel the AVChannel whose description to get
@return amount of bytes needed to hold the output string, or a negative AVERROR
        on failure. If the returned value is bigger than buf_size, then the
        string was truncated.

func AVChannelDescriptionBprint(bp *AVBPrint, channelId AVChannel)

AVChannelDescriptionBprint wraps av_channel_description_bprint.

bprint variant of av_channel_description().

Check whether a channel layout is valid, i.e. can possibly describe audio
data.

@param channel_layout input channel layout
@return 1 if channel_layout is valid, 0 otherwise.

func AVChannelLayoutCompare ¶

func AVChannelLayoutCompare(chl *AVChannelLayout, chl1 *AVChannelLayout) (int, error)

AVChannelLayoutCompare wraps av_channel_layout_compare.

Check whether two channel layouts are semantically the same, i.e. the same
channels are present on the same positions in both.

If one of the channel layouts is AV_CHANNEL_ORDER_UNSPEC, while the other is
not, they are considered to be unequal. If both are AV_CHANNEL_ORDER_UNSPEC,
they are considered equal iff the channel counts are the same in both.

@param chl input channel layout
@param chl1 input channel layout
@return 0 if chl and chl1 are equal, 1 if they are not equal. A negative
        AVERROR code if one or both are invalid.

func AVChannelLayoutCopy ¶

func AVChannelLayoutCopy(dst *AVChannelLayout, src *AVChannelLayout) (int, error)

AVChannelLayoutCopy wraps av_channel_layout_copy.

Make a copy of a channel layout. This differs from just assigning src to dst
in that it allocates and copies the map for AV_CHANNEL_ORDER_CUSTOM.

@note the destination channel_layout will be always uninitialized before copy.

@param dst destination channel layout
@param src source channel layout
@return 0 on success, a negative AVERROR on error.

channel layout, except for opaque pointers.

@param channel_layout channel layout to be described
@param buf pre-allocated buffer where to put the generated string
@param buf_size size in bytes of the buffer.
@return amount of bytes needed to hold the output string, or a negative AVERROR
        on failure. If the returned value is bigger than buf_size, then the
        string was truncated.

func AVChannelLayoutDescribeBprint ¶

func AVChannelLayoutDescribeBprint(channelLayout *AVChannelLayout, bp *AVBPrint) (int, error)

func AVChannelLayoutFromString ¶

func AVChannelLayoutFromString(channelLayout *AVChannelLayout, str *CStr) (int, error)

AVChannelLayoutFromString wraps av_channel_layout_from_string.

Initialize a channel layout from a given string description.
The input string can be represented by:
 - the formal channel layout name (returned by av_channel_layout_describe())
 - single or multiple channel names (returned by av_channel_name(), eg. "FL",
   or concatenated with "+", each optionally containing a custom name after
   a "@", eg. "FL@Left+FR@Right+LFE")
 - a decimal or hexadecimal value of a native channel layout (eg. "4" or "0x4")
 - the number of channels with default layout (eg. "4c")
 - the number of unordered channels (eg. "4C" or "4 channels")
 - the ambisonic order followed by optional non-diegetic channels (eg.
   "ambisonic 2+stereo")

@param channel_layout input channel layout
@param str string describing the channel layout
@return 0 channel layout was detected, AVERROR_INVALIDATATA otherwise

func AVChannelLayoutIndexFromChannel ¶

func AVChannelLayoutIndexFromChannel(channelLayout *AVChannelLayout, channel AVChannel) (int, error)

AVChannelLayoutIndexFromChannel wraps av_channel_layout_index_from_channel.

Get the index of a given channel in a channel layout. In case multiple
channels are found, only the first match will be returned.

@param channel_layout input channel layout
@param channel the channel whose index to obtain
@return index of channel in channel_layout on success or a negative number if

@param name string describing the channel whose index to obtain
@return a channel index described by the given string, or a negative AVERROR
        value.

func AVChannelLayoutSubset ¶

func AVChannelLayoutSubset(channelLayout *AVChannelLayout, mask uint64) uint64

AVChannelLayoutSubset wraps av_channel_layout_subset.

Find out what channels from a given set are present in a channel layout,
without regard for their positions.

        - -1 if `a < b`
        - `INT_MIN` if one of the values is of the form `0 / 0`

func AVCodecClose ¶

func AVCodecClose(avctx *AVCodecContext) (int, error)

AVCodecClose wraps avcodec_close.

Close a given AVCodecContext and free all the data associated with it
(but not the AVCodecContext itself).

Calling this function on an AVCodecContext that hasn't been opened will free
the codec-specific data allocated in avcodec_alloc_context3() with a non-NULL
codec. Subsequent calls will do nothing.

@note Do not use this function. Use avcodec_free_context() to destroy a
codec context (either open or closed). Opening and closing a codec context
multiple times is not supported anymore -- use multiple codec contexts
instead.

func AVCodecDefaultGetBuffer2 ¶

func AVCodecDefaultGetBuffer2(s *AVCodecContext, frame *AVFrame, flags int) (int, error)

AVCodecDefaultGetBuffer2 wraps avcodec_default_get_buffer2.

The default callback for AVCodecContext.get_buffer2(). It is made public so
it can be called by custom get_buffer2() implementations for decoders without
AV_CODEC_CAP_DR1 set.

func AVCodecDefaultGetEncodeBuffer ¶

func AVCodecDefaultGetEncodeBuffer(s *AVCodecContext, pkt *AVPacket, flags int) (int, error)

AVCodecDefaultGetEncodeBuffer wraps avcodec_default_get_encode_buffer.

AV_CODEC_CAP_DR1 set.

func AVCodecEncodeSubtitle ¶

func AVCodecEncodeSubtitle(avctx *AVCodecContext, buf unsafe.Pointer, bufSize int, sub *AVSubtitle) (int, error)

AVCodecEncodeSubtitle wraps avcodec_encode_subtitle.

func AVCodecFillAudioFrame ¶

func AVCodecFillAudioFrame(frame *AVFrame, nbChannels int, sampleFmt AVSampleFormat, buf unsafe.Pointer, bufSize int, align int) (int, error)

AVCodecFillAudioFrame wraps avcodec_fill_audio_frame.

Fill AVFrame audio data and linesize pointers.

The buffer buf must be a preallocated buffer with a size big enough
to contain the specified samples amount. The filled AVFrame data
pointers will point to this buffer.

AVFrame extended_data channel pointers are allocated if necessary for
planar audio.

@param frame       the AVFrame
                   frame->nb_samples must be set prior to calling the
                   function. This function fills in frame->data,
                   frame->extended_data, frame->linesize[0].
@param nb_channels channel count
@param sample_fmt  sample format
@param buf         buffer to use for frame data
@param buf_size    size of buffer
@param align       plane size sample alignment (0 = default)
@return            >=0 on success, negative error code on failure
@todo return the size in bytes required to store the samples in
case of success, at the next libavutil bump

func AVCodecFlushBuffers ¶

func AVCodecFlushBuffers(avctx *AVCodecContext)

AVCodecFlushBuffers wraps avcodec_flush_buffers.

Reset the internal codec state / flush internal buffers. Should be called
e.g. when seeking or when switching to a different stream.

@note for decoders, this function just releases any references the decoder
might keep internally, but the caller's references remain valid.

@note for encoders, this function will only do something if the encoder
declares support for AV_CODEC_CAP_ENCODER_FLUSH. When called, the encoder
will drain any remaining packets, and can then be re-used for a different
stream (as opposed to sending a null frame which will leave the encoder
in a permanent EOF state after draining). This can be desirable if the
cost of tearing down and replacing the encoder instance is high.

func AVCodecFreeContext ¶

func AVCodecFreeContext(avctx **AVCodecContext)

AVCodecFreeContext wraps avcodec_free_context.

Free the codec context and everything associated with it and write NULL to
the provided pointer.

func AVCodecGetHWFramesParameters ¶ added in v0.5.0

func AVCodecGetHWFramesParameters(avctx *AVCodecContext, deviceRef *AVBufferRef, hwPixFmt AVPixelFormat, outFramesRef **AVBufferRef) (int, error)

AVCodecGetHWFramesParameters wraps avcodec_get_hw_frames_parameters.

Create and return a AVHWFramesContext with values adequate for hardware
decoding. This is meant to get called from the get_format callback, and is
a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
This API is for decoding with certain hardware acceleration modes/APIs only.

The returned AVHWFramesContext is not initialized. The caller must do this
with av_hwframe_ctx_init().

Calling this function is not a requirement, but makes it simpler to avoid
codec or hardware API specific details when manually allocating frames.

Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
it unnecessary to call this function or having to care about
AVHWFramesContext initialization at all.

There are a number of requirements for calling this function:

- It must be called from get_format with the same avctx parameter that was
  passed to get_format. Calling it outside of get_format is not allowed, and
  can trigger undefined behavior.
- The function is not always supported (see description of return values).
  Even if this function returns successfully, hwaccel initialization could
  fail later. (The degree to which implementations check whether the stream
  is actually supported varies. Some do this check only after the user's
  get_format callback returns.)
- The hw_pix_fmt must be one of the choices suggested by get_format. If the
  user decides to use a AVHWFramesContext prepared with this API function,
  the user must return the same hw_pix_fmt from get_format.
- The device_ref passed to this function must support the given hw_pix_fmt.
- After calling this API function, it is the user's responsibility to
  initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
  and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
  before returning from get_format (this is implied by the normal
  AVCodecContext.hw_frames_ctx API rules).
- The AVHWFramesContext parameters may change every time time get_format is
  called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
  you are inherently required to go through this process again on every
  get_format call.
- It is perfectly possible to call this function without actually using
  the resulting AVHWFramesContext. One use-case might be trying to reuse a
  previously initialized AVHWFramesContext, and calling this API function
  only to test whether the required frame parameters have changed.
- Fields that use dynamically allocated values of any kind must not be set
  by the user unless setting them is explicitly allowed by the documentation.
  If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
  the new free callback must call the potentially set previous free callback.
  This API call may set any dynamically allocated fields, including the free
  callback.

The function will set at least the following fields on AVHWFramesContext
(potentially more, depending on hwaccel API):

- All fields set by av_hwframe_ctx_alloc().
- Set the format field to hw_pix_fmt.
- Set the sw_format field to the most suited and most versatile format. (An
  implication is that this will prefer generic formats over opaque formats
  with arbitrary restrictions, if possible.)
- Set the width/height fields to the coded frame size, rounded up to the
  API-specific minimum alignment.
- Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
  field to the number of maximum reference surfaces possible with the codec,
  plus 1 surface for the user to work (meaning the user can safely reference
  at most 1 decoded surface at a time), plus additional buffering introduced
  by frame threading. If the hwaccel does not require pre-allocation, the
  field is left to 0, and the decoder will allocate new surfaces on demand
  during decoding.
- Possibly AVHWFramesContext.hwctx fields, depending on the underlying
  hardware API.

Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
with basic frame parameters set.

The function is stateless, and does not change the AVCodecContext or the
device_ref AVHWDeviceContext.

@param avctx The context which is currently calling get_format, and which
             implicitly contains all state needed for filling the returned
             AVHWFramesContext properly.
@param device_ref A reference to the AVHWDeviceContext describing the device
                  which will be used by the hardware decoder.
@param hw_pix_fmt The hwaccel format you are going to return from get_format.
@param out_frames_ref On success, set to a reference to an _uninitialized_
                      AVHWFramesContext, created from the given device_ref.
                      Fields will be set to values required for decoding.
                      Not changed if an error is returned.
@return zero on success, a negative value on error. The following error codes
        have special semantics:
     AVERROR(ENOENT): the decoder does not support this functionality. Setup
                      is always manual, or it is a decoder which does not
                      support setting AVCodecContext.hw_frames_ctx at all,
                      or it is a software format.
     AVERROR(EINVAL): it is known that hardware decoding is not supported for
                      this configuration, or the device_ref is not supported
                      for the hwaccel referenced by hw_pix_fmt.

@return a non-zero number if codec is an encoder, zero otherwise

func AVCodecIsOpen ¶

func AVCodecIsOpen(s *AVCodecContext) (int, error)

AVCodecIsOpen wraps avcodec_is_open.

@return a positive value if s is open (i.e. avcodec_open2() was called on it
with no corresponding avcodec_close()), 0 otherwise.

func AVCodecOpen2 ¶

func AVCodecOpen2(avctx *AVCodecContext, codec *AVCodec, options **AVDictionary) (int, error)

AVCodecOpen2 wraps avcodec_open2.

Initialize the AVCodecContext to use the given AVCodec. Prior to using this
function the context has to be allocated with avcodec_alloc_context3().

The functions avcodec_find_decoder_by_name(), avcodec_find_encoder_by_name(),
avcodec_find_decoder() and avcodec_find_encoder() provide an easy way for
retrieving a codec.

Depending on the codec, you might need to set options in the codec context
also for decoding (e.g. width, height, or the pixel or audio sample format in
the case the information is not available in the bitstream, as when decoding
raw audio or video).

Options in the codec context can be set either by setting them in the options
AVDictionary, or by setting the values in the context itself, directly or by
using the av_opt_set() API before calling this function.

Example:
@code
av_dict_set(&opts, "b", "2.5M", 0);
codec = avcodec_find_decoder(AV_CODEC_ID_H264);
if (!codec)
    exit(1);

context = avcodec_alloc_context3(codec);

if (avcodec_open2(context, codec, opts) < 0)
    exit(1);
@endcode

In the case AVCodecParameters are available (e.g. when demuxing a stream
using libavformat, and accessing the AVStream contained in the demuxer), the
codec parameters can be copied to the codec context using
avcodec_parameters_to_context(), as in the following example:

@code
AVStream *stream = ...;
context = avcodec_alloc_context3(codec);
if (avcodec_parameters_to_context(context, stream->codecpar) < 0)
    exit(1);
if (avcodec_open2(context, codec, NULL) < 0)
    exit(1);
@endcode

@note Always call this function before using decoding routines (such as
@ref avcodec_receive_frame()).

@param avctx The context to initialize.
@param codec The codec to open this context for. If a non-NULL codec has been
             previously passed to avcodec_alloc_context3() or
             for this context, then this parameter MUST be either NULL or
             equal to the previously passed codec.
@param options A dictionary filled with AVCodecContext and codec-private
               options, which are set on top of the options already set in
               avctx, can be NULL. On return this object will be filled with
               options that were not found in the avctx codec context.

@return zero on success, a negative value on error
@see avcodec_alloc_context3(), avcodec_find_decoder(), avcodec_find_encoder(),
     av_dict_set(), av_opt_set(), av_opt_find(), avcodec_parameters_to_context()

func AVCodecParametersCopy ¶

func AVCodecParametersCopy(dst *AVCodecParameters, src *AVCodecParameters) (int, error)

AVCodecParametersCopy wraps avcodec_parameters_copy.

Copy the contents of src to dst. Any allocated fields in dst are freed and
replaced with newly allocated duplicates of the corresponding fields in src.

@return >= 0 on success, a negative AVERROR code on failure.

func AVCodecParametersFree ¶

func AVCodecParametersFree(par **AVCodecParameters)

AVCodecParametersFree wraps avcodec_parameters_free.

Free an AVCodecParameters instance and everything associated with it and
write NULL to the supplied pointer.

func AVCodecParametersFromContext ¶

func AVCodecParametersFromContext(par *AVCodecParameters, codec *AVCodecContext) (int, error)

AVCodecParametersFromContext wraps avcodec_parameters_from_context.

Fill the parameters struct based on the values from the supplied codec
context. Any allocated fields in par are freed and replaced with duplicates
of the corresponding fields in codec.

@return >= 0 on success, a negative AVERROR code on failure

func AVCodecParametersToContext ¶

func AVCodecParametersToContext(codec *AVCodecContext, par *AVCodecParameters) (int, error)

AVCodecParametersToContext wraps avcodec_parameters_to_context.

Fill the codec context based on the values from the supplied codec
parameters. Any allocated fields in codec that have a corresponding field in
par are freed and replaced with duplicates of the corresponding field in par.
Fields in codec that do not have a counterpart in par are not touched.

@return >= 0 on success, a negative AVERROR code on failure.

func AVCodecPixFmtToCodecTag ¶

func AVCodecPixFmtToCodecTag(pixFmt AVPixelFormat) uint

AVCodecPixFmtToCodecTag wraps avcodec_pix_fmt_to_codec_tag.

Return a value representing the fourCC code associated to the
pixel format pix_fmt, or 0 if no associated fourCC code can be
found.

func AVCodecReceiveFrame ¶

func AVCodecReceiveFrame(avctx *AVCodecContext, frame *AVFrame) (int, error)

AVCodecReceiveFrame wraps avcodec_receive_frame.

Return decoded output data from a decoder or encoder (when the
@ref AV_CODEC_FLAG_RECON_FRAME flag is used).

@param avctx codec context
@param frame This will be set to a reference-counted video or audio
             frame (depending on the decoder type) allocated by the
             codec. Note that the function will always call
             av_frame_unref(frame) before doing anything else.

@retval 0                success, a frame was returned
@retval AVERROR(EAGAIN)  output is not available in this state - user must
                         try to send new input
@retval AVERROR_EOF      the codec has been fully flushed, and there will be
                         no more output frames
@retval AVERROR(EINVAL)  codec not opened, or it is an encoder without the
                         @ref AV_CODEC_FLAG_RECON_FRAME flag enabled
@retval "other negative error code" legitimate decoding errors

func AVCodecReceivePacket ¶

func AVCodecReceivePacket(avctx *AVCodecContext, avpkt *AVPacket) (int, error)

AVCodecReceivePacket wraps avcodec_receive_packet.

Read encoded data from the encoder.

@param avctx codec context
@param avpkt This will be set to a reference-counted packet allocated by the
             encoder. Note that the function will always call
             av_packet_unref(avpkt) before doing anything else.
@retval 0               success
@retval AVERROR(EAGAIN) output is not available in the current state - user must
                        try to send input
@retval AVERROR_EOF     the encoder has been fully flushed, and there will be no
                        more output packets
@retval AVERROR(EINVAL) codec not opened, or it is a decoder
@retval "another negative error code" legitimate encoding errors

func AVCodecSendFrame ¶

func AVCodecSendFrame(avctx *AVCodecContext, frame *AVFrame) (int, error)

AVCodecSendFrame wraps avcodec_send_frame.

Supply a raw video or audio frame to the encoder. Use avcodec_receive_packet()
to retrieve buffered output packets.

@param avctx     codec context
@param[in] frame AVFrame containing the raw audio or video frame to be encoded.
                 Ownership of the frame remains with the caller, and the
                 encoder will not write to the frame. The encoder may create
                 a reference to the frame data (or copy it if the frame is
                 not reference-counted).
                 It can be NULL, in which case it is considered a flush
                 packet.  This signals the end of the stream. If the encoder
                 still has packets buffered, it will return them after this
                 call. Once flushing mode has been entered, additional flush
                 packets are ignored, and sending frames will return
                 AVERROR_EOF.

                 For audio:
                 If AV_CODEC_CAP_VARIABLE_FRAME_SIZE is set, then each frame
                 can have any number of samples.
                 If it is not set, frame->nb_samples must be equal to
                 avctx->frame_size for all frames except the last.
                 The final frame may be smaller than avctx->frame_size.
@retval 0                 success
@retval AVERROR(EAGAIN)   input is not accepted in the current state - user must
                          read output with avcodec_receive_packet() (once all
                          output is read, the packet should be resent, and the
                          call will not fail with EAGAIN).
@retval AVERROR_EOF       the encoder has been flushed, and no new frames can
                          be sent to it
@retval AVERROR(EINVAL)   codec not opened, it is a decoder, or requires flush
@retval AVERROR(ENOMEM)   failed to add packet to internal queue, or similar
@retval "another negative error code" legitimate encoding errors

func AVCodecSendPacket ¶

func AVCodecSendPacket(avctx *AVCodecContext, avpkt *AVPacket) (int, error)

AVCodecSendPacket wraps avcodec_send_packet.

Supply raw packet data as input to a decoder.

Internally, this call will copy relevant AVCodecContext fields, which can
influence decoding per-packet, and apply them when the packet is actually
decoded. (For example AVCodecContext.skip_frame, which might direct the
decoder to drop the frame contained by the packet sent with this function.)

@warning The input buffer, avpkt->data must be AV_INPUT_BUFFER_PADDING_SIZE
         larger than the actual read bytes because some optimized bitstream
         readers read 32 or 64 bits at once and could read over the end.

@note The AVCodecContext MUST have been opened with @ref avcodec_open2()
      before packets may be fed to the decoder.

@param avctx codec context
@param[in] avpkt The input AVPacket. Usually, this will be a single video
                 frame, or several complete audio frames.
                 Ownership of the packet remains with the caller, and the
                 decoder will not write to the packet. The decoder may create
                 a reference to the packet data (or copy it if the packet is
                 not reference-counted).
                 Unlike with older APIs, the packet is always fully consumed,
                 and if it contains multiple frames (e.g. some audio codecs),
                 will require you to call avcodec_receive_frame() multiple
                 times afterwards before you can send a new packet.
                 It can be NULL (or an AVPacket with data set to NULL and
                 size set to 0); in this case, it is considered a flush
                 packet, which signals the end of the stream. Sending the
                 first flush packet will return success. Subsequent ones are
                 unnecessary and will return AVERROR_EOF. If the decoder
                 still has frames buffered, it will return them after sending
                 a flush packet.

@retval 0                 success
@retval AVERROR(EAGAIN)   input is not accepted in the current state - user
                          must read output with avcodec_receive_frame() (once
                          all output is read, the packet should be resent,
                          and the call will not fail with EAGAIN).
@retval AVERROR_EOF       the decoder has been flushed, and no new packets can be
                          sent to it (also returned if more than 1 flush
                          packet is sent)
@retval AVERROR(EINVAL)   codec not opened, it is an encoder, or requires flush
@retval AVERROR(ENOMEM)   failed to add packet to internal queue, or similar
@retval "another negative error code" legitimate decoding errors

av_compare_mod(0x11, 0x02, 0x20) > 0 // since 0x11 % 0x20 (0x11) > 0x02 % 0x20 (0x02)
@endcode

@param a Operand
@param b Operand
@param mod Divisor; must be a power of 2
@return
        - a negative value if `a % mod < b % mod`
        - a positive value if `a % mod > b % mod`
        - zero             if `a % mod == b % mod`

func AVCompareTs ¶

func AVCompareTs(tsA int64, tbA *AVRational, tsB int64, tbB *AVRational) (int, error)

AVCompareTs wraps av_compare_ts.

        - 1 if `ts_a` is after `ts_b`
        - 0 if they represent the same position

@warning
The result of the function is undefined if one of the timestamps is outside
the `int64_t` range when represented in the other's timebase.

@param src   Pointer to the source AVDictionary struct to copy items from.
@param flags Flags to use when setting entries in *dst

@return 0 on success, negative AVERROR code on failure. If dst was allocated

AVDictParseString wraps av_dict_parse_string.

Parse the key/value pairs list and add the parsed entries to a dictionary.

In case of failure, all the successfully set entries are stored in
*pm. You may need to manually free the created dictionary.

@param key_val_sep  A 0-terminated list of characters used to separate
                    key from value
@param pairs_sep    A 0-terminated list of characters used to separate
                    two pairs from each other
@param flags        Flags to use when adding to the dictionary.
                    ::AV_DICT_DONT_STRDUP_KEY and ::AV_DICT_DONT_STRDUP_VAL
                    are ignored since the key/value tokens will always
                    be duplicated.

@return             0 on success, negative AVERROR code on failure

func AVDictSet ¶

func AVDictSet(pm **AVDictionary, key *CStr, value *CStr, flags int) (int, error)

AVDictSet wraps av_dict_set.

Set the given entry in *pm, overwriting an existing entry.

Note: If AV_DICT_DONT_STRDUP_KEY or AV_DICT_DONT_STRDUP_VAL is set,
these arguments will be freed on error.

@warning Adding a new entry to a dictionary invalidates all existing entries
previously returned with av_dict_get() or av_dict_iterate().

@param pm        Pointer to a pointer to a dictionary struct. If *pm is NULL
                 a dictionary struct is allocated and put in *pm.

negative value otherwise

func AVFilterGraphFree ¶

func AVFilterGraphFree(graph **AVFilterGraph)

AVFilterGraphFree wraps avfilter_graph_free.

Free a graph, destroy its links, and set *graph to NULL.
If *graph is NULL, do nothing.

func AVFilterGraphParse ¶

func AVFilterGraphParse(graph *AVFilterGraph, filters *CStr, inputs *AVFilterInOut, outputs *AVFilterInOut, logCtx unsafe.Pointer) (int, error)

AVFilterGraphParse wraps avfilter_graph_parse.

Add a graph described by a string to a graph.

@note The caller must provide the lists of inputs and outputs,
which therefore must be known before calling the function.

@note The inputs parameter describes inputs of the already existing
part of the graph; i.e. from the point of view of the newly created
part, they are outputs. Similarly the outputs parameter describes
outputs of the already existing filters, which are provided as
inputs to the parsed filters.

@param graph   the filter graph where to link the parsed graph context
@param filters string to be parsed
@param inputs  linked list to the inputs of the graph
@param outputs linked list to the outputs of the graph
@return zero on success, a negative AVERROR code on error

func AVFilterGraphParse2 ¶

func AVFilterGraphParse2(graph *AVFilterGraph, filters *CStr, inputs **AVFilterInOut, outputs **AVFilterInOut) (int, error)

AVFilterGraphParse2 wraps avfilter_graph_parse2.

@param[in]  graph   the filter graph where to link the parsed graph context
@param[in]  filters string to be parsed
@param[out] inputs  a linked list of all free (unlinked) inputs of the
                    parsed graph will be returned here. It is to be freed
                    by the caller using avfilter_inout_free().
@param[out] outputs a linked list of all free (unlinked) outputs of the
                    parsed graph will be returned here. It is to be freed by the
                    caller using avfilter_inout_free().
@return zero on success, a negative AVERROR code on error

@note This function returns the inputs and outputs that are left
unlinked after parsing the graph and the caller then deals with
them.
@note This function makes no reference whatsoever to already
existing parts of the graph and the inputs parameter will on return
contain inputs of the newly parsed part of the graph.  Analogously
the outputs parameter will contain outputs of the newly created
filters.

func AVFilterGraphParsePtr ¶

func AVFilterGraphParsePtr(graph *AVFilterGraph, filters *CStr, inputs **AVFilterInOut, outputs **AVFilterInOut, logCtx unsafe.Pointer) (int, error)

AVFilterGraphParsePtr wraps avfilter_graph_parse_ptr.

Add a graph described by a string to a graph.

In the graph filters description, if the input label of the first
filter is not specified, "in" is assumed; if the output label of
the last filter is not specified, "out" is assumed.

@param graph   the filter graph where to link the parsed graph context
@param filters string to be parsed
@param inputs  pointer to a linked list to the inputs of the graph, may be NULL.
               If non-NULL, *inputs is updated to contain the list of open inputs
               after the parsing, should be freed with avfilter_inout_free().
@param outputs pointer to a linked list to the outputs of the graph, may be NULL.
               If non-NULL, *outputs is updated to contain the list of open outputs
               after the parsing, should be freed with avfilter_inout_free().

func AVFilterGraphQueueCommand ¶

func AVFilterGraphQueueCommand(graph *AVFilterGraph, target *CStr, cmd *CStr, arg *CStr, flags int, ts float64) (int, error)

AVFilterGraphQueueCommand wraps avfilter_graph_queue_command.

Queue a command for one or more filter instances.

@param graph  the filter graph
@param target the filter(s) to which the command should be sent
              "all" sends to all filters
              otherwise it can be a filter or filter instance name
              which will send the command to all matching filters.
@param cmd    the command to sent, for handling simplicity all commands must be alphanumeric only
@param arg    the argument for the command
@param ts     time at which the command should be sent to the filter

@note As this executes commands after this function returns, no return code
      from the filter is provided, also AVFILTER_CMD_FLAG_ONE is not supported.

func AVFilterGraphRequestOldest ¶

func AVFilterGraphRequestOldest(graph *AVFilterGraph) (int, error)

AVFilterGraphRequestOldest wraps avfilter_graph_request_oldest.

Request a frame on the oldest sink link.

If the request returns AVERROR_EOF, try the next.

Note that this function is not meant to be the sole scheduling mechanism
of a filtergraph, only a convenience function to help drain a filtergraph
in a balanced way under normal circumstances.

Also note that AVERROR_EOF does not mean that frames did not arrive on
some of the sinks during the process.
When there are multiple sink links, in case the requested link
returns an EOF, this may cause a filter to flush pending frames
which are sent to another sink link, although unrequested.

@return  the return value of ff_request_frame(),
         or AVERROR_EOF if all links returned AVERROR_EOF

func AVFilterGraphSegmentApply ¶

func AVFilterGraphSegmentApply(seg *AVFilterGraphSegment, flags int, inputs **AVFilterInOut, outputs **AVFilterInOut) (int, error)

AVFilterGraphSegmentApply wraps avfilter_graph_segment_apply.

This functions is currently equivalent to calling the following in sequence:
- avfilter_graph_segment_create_filters();
- avfilter_graph_segment_apply_opts();
- avfilter_graph_segment_init();
- avfilter_graph_segment_link();
failing if any of them fails. This list may be extended in the future.

Since the above functions are idempotent, the caller may call some of them
manually, then do some custom processing on the filtergraph, then call this
function to do the rest.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now
@param[out] inputs passed to avfilter_graph_segment_link()
@param[out] outputs passed to avfilter_graph_segment_link()

@retval "non-negative number" success
@retval "negative error code" failure

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentApplyOpts ¶

func AVFilterGraphSegmentApplyOpts(seg *AVFilterGraphSegment, flags int) (int, error)

AVFilterGraphSegmentApplyOpts wraps avfilter_graph_segment_apply_opts.

Apply parsed options to filter instances in a graph segment.

Walk through all filter instances in the graph segment that have option
dictionaries associated with them and apply those options with
av_opt_set_dict2(..., AV_OPT_SEARCH_CHILDREN). AVFilterParams.opts is
replaced by the dictionary output by av_opt_set_dict2(), which should be
empty (NULL) if all options were successfully applied.

If any options could not be found, this function will continue processing all
other filters and finally return AVERROR_OPTION_NOT_FOUND (unless another
error happens). The calling program may then deal with unapplied options as
it wishes.

Any creation-pending filters (see avfilter_graph_segment_create_filters())
present in the segment will cause this function to fail. AVFilterParams with
no associated filter context are simply skipped.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now

@retval "non-negative number" Success, all options were successfully applied.
@retval AVERROR_OPTION_NOT_FOUND some options were not found in a filter
@retval "another negative error code" other failures

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentCreateFilters ¶

func AVFilterGraphSegmentCreateFilters(seg *AVFilterGraphSegment, flags int) (int, error)

AVFilterGraphSegmentCreateFilters wraps avfilter_graph_segment_create_filters.

Create filters specified in a graph segment.

Walk through the creation-pending AVFilterParams in the segment and create
new filter instances for them.
Creation-pending params are those where AVFilterParams.filter_name is
non-NULL (and hence AVFilterParams.filter is NULL). All other AVFilterParams
instances are ignored.

For any filter created by this function, the corresponding
AVFilterParams.filter is set to the newly-created filter context,
AVFilterParams.filter_name and AVFilterParams.instance_name are freed and set
to NULL.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now

@retval "non-negative number" Success, all creation-pending filters were
                              successfully created
@retval AVERROR_FILTER_NOT_FOUND some filter's name did not correspond to a
                                 known filter
@retval "another negative error code" other failures

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentFree ¶

func AVFilterGraphSegmentFree(seg **AVFilterGraphSegment)

AVFilterGraphSegmentFree wraps avfilter_graph_segment_free.

Free the provided AVFilterGraphSegment and everything associated with it.

@param seg double pointer to the AVFilterGraphSegment to be freed. NULL will
be written to this pointer on exit from this function.

@note
The filter contexts (AVFilterParams.filter) are owned by AVFilterGraph rather
than AVFilterGraphSegment, so they are not freed.

func AVFilterGraphSegmentInit ¶

func AVFilterGraphSegmentInit(seg *AVFilterGraphSegment, flags int) (int, error)

AVFilterGraphSegmentInit wraps avfilter_graph_segment_init.

Initialize all filter instances in a graph segment.

Walk through all filter instances in the graph segment and call
avfilter_init_dict(..., NULL) on those that have not been initialized yet.

Any creation-pending filters (see avfilter_graph_segment_create_filters())
present in the segment will cause this function to fail. AVFilterParams with
no associated filter context or whose filter context is already initialized,
are simply skipped.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now

@retval "non-negative number" Success, all filter instances were successfully
                              initialized
@retval "negative error code" failure

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentLink ¶

func AVFilterGraphSegmentLink(seg *AVFilterGraphSegment, flags int, inputs **AVFilterInOut, outputs **AVFilterInOut) (int, error)

AVFilterGraphSegmentLink wraps avfilter_graph_segment_link.

Link filters in a graph segment.

Walk through all filter instances in the graph segment and try to link all
unlinked input and output pads. Any creation-pending filters (see
avfilter_graph_segment_create_filters()) present in the segment will cause
this function to fail. Disabled filters and already linked pads are skipped.

Every filter output pad that has a corresponding AVFilterPadParams with a
non-NULL label is
- linked to the input with the matching label, if one exists;
- exported in the outputs linked list otherwise, with the label preserved.
Unlabeled outputs are
- linked to the first unlinked unlabeled input in the next non-disabled
  filter in the chain, if one exists
- exported in the ouputs linked list otherwise, with NULL label

Similarly, unlinked input pads are exported in the inputs linked list.

@param seg the filtergraph segment to process
@param flags reserved for future use, caller must set to 0 for now
@param[out] inputs  a linked list of all free (unlinked) inputs of the
                    filters in this graph segment will be returned here. It
                    is to be freed by the caller using avfilter_inout_free().
@param[out] outputs a linked list of all free (unlinked) outputs of the
                    filters in this graph segment will be returned here. It
                    is to be freed by the caller using avfilter_inout_free().

@retval "non-negative number" success
@retval "negative error code" failure

@note Calling this function multiple times is safe, as it is idempotent.

func AVFilterGraphSegmentParse ¶

func AVFilterGraphSegmentParse(graph *AVFilterGraph, graphStr *CStr, flags int, seg **AVFilterGraphSegment) (int, error)

AVFilterGraphSegmentParse wraps avfilter_graph_segment_parse.

Parse a textual filtergraph description into an intermediate form.

This intermediate representation is intended to be modified by the caller as
described in the documentation of AVFilterGraphSegment and its children, and
then applied to the graph either manually or with other
avfilter_graph_segment_*() functions. See the documentation for
avfilter_graph_segment_apply() for the canonical way to apply
AVFilterGraphSegment.

@param graph Filter graph the parsed segment is associated with. Will only be
             used for logging and similar auxiliary purposes. The graph will
             not be actually modified by this function - the parsing results
             are instead stored in seg for further processing.
@param graph_str a string describing the filtergraph segment
@param flags reserved for future use, caller must set to 0 for now
@param seg A pointer to the newly-created AVFilterGraphSegment is written
           here on success. The graph segment is owned by the caller and must
           be freed with avfilter_graph_segment_free() before graph itself is
           freed.

@retval "non-negative number" success
@retval "negative error code" failure

func AVFilterGraphSendCommand ¶

func AVFilterGraphSendCommand(graph *AVFilterGraph, target *CStr, cmd *CStr, arg *CStr, res *CStr, resLen int, flags int) (int, error)

AVFilterGraphSendCommand wraps avfilter_graph_send_command.

Send a command to one or more filter instances.

@param graph  the filter graph
@param target the filter(s) to which the command should be sent
              "all" sends to all filters
              otherwise it can be a filter or filter instance name
              which will send the command to all matching filters.
@param cmd    the command to send, for handling simplicity all commands must be alphanumeric only
@param arg    the argument for the command
@param res    a buffer with size res_size where the filter(s) can return a response.

@returns >=0 on success otherwise an error code.
             AVERROR(ENOSYS) on unsupported commands

func AVFilterGraphSetAutoConvert ¶

func AVFilterGraphSetAutoConvert(graph *AVFilterGraph, flags uint)

AVFilterGraphSetAutoConvert wraps avfilter_graph_set_auto_convert.

Enable or disable automatic format conversion inside the graph.

Note that format conversion can still happen inside explicitly inserted
scale and aresample filters.

@param flags  any of the AVFILTER_AUTO_CONVERT_* constants

func AVFilterInitDict ¶

func AVFilterInitDict(ctx *AVFilterContext, options **AVDictionary) (int, error)

AVFilterInitDict wraps avfilter_init_dict.

Initialize a filter with the supplied dictionary of options.

@param ctx     uninitialized filter context to initialize
@param options An AVDictionary filled with options for this filter. On
               return this parameter will be destroyed and replaced with
               a dict containing options that were not found. This dictionary
               must be freed by the caller.
               May be NULL, then this function is equivalent to
               avfilter_init_str() with the second parameter set to NULL.
@return 0 on success, a negative AVERROR on failure

@note This function and avfilter_init_str() do essentially the same thing,
the difference is in manner in which the options are passed. It is up to the
calling code to choose whichever is more preferable. The two functions also
behave differently when some of the provided options are not declared as
supported by the filter. In such a case, avfilter_init_str() will fail, but
this function will leave those extra options in the options AVDictionary and
continue as usual.

func AVFilterInitStr ¶

func AVFilterInitStr(ctx *AVFilterContext, args *CStr) (int, error)

AVFilterInitStr wraps avfilter_init_str.

Initialize a filter with the supplied parameters.

@param ctx  uninitialized filter context to initialize
@param args Options to initialize the filter with. This must be a
            ':'-separated list of options in the 'key=value' form.
            May be NULL if the options have been set directly using the
            AVOptions API or there are no options that need to be set.
@return 0 on success, a negative AVERROR on failure

func AVFilterInoutFree ¶

func AVFilterInoutFree(inout **AVFilterInOut)

AVFilterInoutFree wraps avfilter_inout_free.

Free the supplied list of AVFilterInOut and set *inout to NULL.

func AVFilterVersion() uint

AVFilterVersion wraps avfilter_version.

Return the LIBAVFILTER_VERSION_INT constant.

func AVFindBestStream ¶

func AVFindBestStream(ic *AVFormatContext, _type AVMediaType, wantedStreamNb int, relatedStream int, decoderRet **AVCodec, flags int) (int, error)

AVFindBestStream wraps av_find_best_stream.

Find the "best" stream in the file.
The best stream is determined according to various heuristics as the most
likely to be what the user expects.
If the decoder parameter is non-NULL, av_find_best_stream will find the
default decoder for the stream's codec; streams for which no decoder can
be found are ignored.

@param ic                media file handle
@param type              stream type: video, audio, subtitles, etc.
@param wanted_stream_nb  user-requested stream number,
                         or -1 for automatic selection
@param related_stream    try to find a stream related (eg. in the same
                         program) to this one, or -1 if none
@param decoder_ret       if non-NULL, returns the decoder for the
                         selected stream
@param flags             flags; none are currently defined

@return  the non-negative stream number in case of success,
         AVERROR_STREAM_NOT_FOUND if no stream with the requested type
         could be found,
         AVERROR_DECODER_NOT_FOUND if streams were found but no decoder

@note  If av_find_best_stream returns successfully and decoder_ret is not
       NULL, then *decoder_ret is guaranteed to be set to a valid AVCodec.

func AVFindDefaultStreamIndex ¶

func AVFindDefaultStreamIndex(s *AVFormatContext) (int, error)

AVFindDefaultStreamIndex wraps av_find_default_stream_index.

func AVFormatAllocOutputContext2 ¶

func AVFormatAllocOutputContext2(ctx **AVFormatContext, oformat *AVOutputFormat, formatName *CStr, filename *CStr) (int, error)

AVFormatAllocOutputContext2 wraps avformat_alloc_output_context2.

Allocate an AVFormatContext for an output format.
avformat_free_context() can be used to free the context and
everything allocated by the framework within it.

@param ctx           pointee is set to the created format context,
                     or to NULL in case of failure
@param oformat       format to use for allocating the context, if NULL
                     format_name and filename are used instead
@param format_name   the name of output format to use for allocating the
                     context, if NULL filename is used instead
@param filename      the name of the filename to use for allocating the
                     context, may be NULL

@return  >= 0 in case of success, a negative AVERROR code in case of
         failure

func AVFormatCloseInput ¶

func AVFormatCloseInput(s **AVFormatContext)

AVFormatCloseInput wraps avformat_close_input.

Close an opened input AVFormatContext. Free it and all its contents
and set *s to NULL.

func AVFormatFindStreamInfo ¶

func AVFormatFindStreamInfo(ic *AVFormatContext, options **AVDictionary) (int, error)

AVFormatFindStreamInfo wraps avformat_find_stream_info.

Read packets of a media file to get stream information. This
is useful for file formats with no headers such as MPEG. This
function also computes the real framerate in case of MPEG-2 repeat
frame mode.
The logical file position is not changed by this function;
examined packets may be buffered for later processing.

@param ic media file handle
@param options  If non-NULL, an ic.nb_streams long array of pointers to
                dictionaries, where i-th member contains options for
                codec corresponding to i-th stream.
                On return each dictionary will be filled with options that were not found.
@return >=0 if OK, AVERROR_xxx on error

@note this function isn't guaranteed to open all the codecs, so
      options being non-empty at return is a perfectly normal behavior.

@todo Let the user decide somehow what information is needed so that
      we do not waste time getting stuff the user does not need.

func AVFormatFlush ¶

func AVFormatFlush(s *AVFormatContext) (int, error)

AVFormatFlush wraps avformat_flush.

Discard all internally buffered data. This can be useful when dealing with
discontinuities in the byte stream. Generally works only with formats that
can resync. This includes headerless formats like MPEG-TS/TS but should also
work with NUT, Ogg and in a limited way AVI for example.

The set of streams, the detected duration, stream parameters and codecs do
not change when calling this function. If you want a complete reset, it's
better to open a new AVFormatContext.

This does not flush the AVIOContext (s->pb). If necessary, call
avio_flush(s->pb) before calling this function.

@param s media file handle
@return >=0 on success, error code otherwise

func AVFormatFreeContext ¶

func AVFormatFreeContext(s *AVFormatContext)

AVFormatFreeContext wraps avformat_free_context.

@return the number of index entries in the stream

func AVFormatInitOutput ¶

func AVFormatInitOutput(s *AVFormatContext, options **AVDictionary) (int, error)

AVFormatInitOutput wraps avformat_init_output.

Allocate the stream private data and initialize the codec, but do not write the header.
May optionally be used before avformat_write_header() to initialize stream parameters
before actually writing the header.
If using this function, do not pass the same options to avformat_write_header().

@param s        Media file handle, must be allocated with
                avformat_alloc_context().
                Its \ref AVFormatContext.oformat "oformat" field must be set
                to the desired output format;
                Its \ref AVFormatContext.pb "pb" field must be set to an
                already opened ::AVIOContext.
@param options  An ::AVDictionary filled with AVFormatContext and
                muxer-private options.
                On return this parameter will be destroyed and replaced with
                a dict containing options that were not found. May be NULL.

@retval AVSTREAM_INIT_IN_WRITE_HEADER On success, if the codec requires
                                      avformat_write_header to fully initialize.
@retval AVSTREAM_INIT_IN_INIT_OUTPUT  On success, if the codec has been fully
                                      initialized.
@retval AVERROR                       Anegative AVERROR on failure.

@see av_opt_find, av_dict_set, avio_open, av_oformat_next, avformat_write_header.

func AVFormatInjectGlobalSideData ¶

func AVFormatInjectGlobalSideData(s *AVFormatContext)

AVFormatInjectGlobalSideData wraps av_format_inject_global_side_data.

This function will cause global side data to be injected in the next packet
of each stream as well as after any subsequent seek.

@note global side data is always available in every AVStream's
      @ref AVCodecParameters.coded_side_data "codecpar side data" array, and
      in a @ref AVCodecContext.coded_side_data "decoder's side data" array if
      initialized with said stream's codecpar.
@see av_packet_side_data_get()

func AVFormatMatchStreamSpecifier ¶

func AVFormatMatchStreamSpecifier(s *AVFormatContext, st *AVStream, spec *CStr) (int, error)

spec.

See the "stream specifiers" chapter in the documentation for the syntax
of spec.

         0  if st is not matched by spec;
         AVERROR code if spec is invalid

@note  A stream specifier can match several streams in the format.

func AVFormatNetworkDeinit ¶

func AVFormatNetworkDeinit() (int, error)

once for each time you called avformat_network_init.

func AVFormatNetworkInit ¶

func AVFormatNetworkInit() (int, error)

AVFormatNetworkInit wraps avformat_network_init.

Do global initialization of network libraries. This is optional,
and not recommended anymore.

This functions only exists to work around thread-safety issues
with older GnuTLS or OpenSSL libraries. If libavformat is linked
to newer versions of those libraries, or if you do not use them,
calling this function is unnecessary. Otherwise, you need to call
this function before any other threads using them are started.

This function will be deprecated once support for older GnuTLS and
OpenSSL libraries is removed, and this function has no purpose
anymore.

func AVFormatOpenInput ¶

func AVFormatOpenInput(ps **AVFormatContext, url *CStr, fmt *AVInputFormat, options **AVDictionary) (int, error)

AVFormatOpenInput wraps avformat_open_input.

Open an input stream and read the header. The codecs are not opened.
The stream must be closed with avformat_close_input().

@param ps       Pointer to user-supplied AVFormatContext (allocated by
                avformat_alloc_context). May be a pointer to NULL, in
                which case an AVFormatContext is allocated by this
                function and written into ps.
                Note that a user-supplied AVFormatContext will be freed
                on failure.
@param url      URL of the stream to open.
@param fmt      If non-NULL, this parameter forces a specific input format.
                Otherwise the format is autodetected.
@param options  A dictionary filled with AVFormatContext and demuxer-private
                options.
                On return this parameter will be destroyed and replaced with
                a dict containing options that were not found. May be NULL.

@return 0 on success, a negative AVERROR on failure.

@note If you want to use custom IO, preallocate the format context and set its pb field.

func AVFormatQueryCodec ¶

func AVFormatQueryCodec(ofmt *AVOutputFormat, codecId AVCodecID, stdCompliance int) (int, error)

AVFormatQueryCodec wraps avformat_query_codec.

Test if the given container can store a codec.

@param ofmt           container to check for compatibility
@param codec_id       codec to potentially store in container
@param std_compliance standards compliance level, one of FF_COMPLIANCE_*

@return 1 if codec with ID codec_id can be stored in ofmt, 0 if it cannot.
        A negative number if this information is not available.

func AVFormatQueueAttachedPictures ¶

func AVFormatQueueAttachedPictures(s *AVFormatContext) (int, error)

AVFormatQueueAttachedPictures wraps avformat_queue_attached_pictures.

func AVFormatSeekFile ¶

func AVFormatSeekFile(s *AVFormatContext, streamIndex int, minTs int64, ts int64, maxTs int64, flags int) (int, error)

AVFormatSeekFile wraps avformat_seek_file.

Seek to timestamp ts.
Seeking will be done so that the point from which all active streams
can be presented successfully will be closest to ts and within min/max_ts.
Active streams are all streams that have AVStream.discard < AVDISCARD_ALL.

If flags contain AVSEEK_FLAG_BYTE, then all timestamps are in bytes and
are the file position (this may not be supported by all demuxers).
If flags contain AVSEEK_FLAG_FRAME, then all timestamps are in frames
in the stream with stream_index (this may not be supported by all demuxers).
Otherwise all timestamps are in units of the stream selected by stream_index
or if stream_index is -1, in AV_TIME_BASE units.
If flags contain AVSEEK_FLAG_ANY, then non-keyframes are treated as
keyframes (this may not be supported by all demuxers).
If flags contain AVSEEK_FLAG_BACKWARD, it is ignored.

@param s            media file handle
@param stream_index index of the stream which is used as time base reference
@param min_ts       smallest acceptable timestamp
@param ts           target timestamp
@param max_ts       largest acceptable timestamp
@param flags        flags

AVFormatTransferInternalStreamTimingInfo wraps avformat_transfer_internal_stream_timing_info.

Transfer internal timing information from one stream to another.

This function is useful when doing stream copy.

@param ofmt     target output format for ost
@param ost      output stream which needs timings copy and adjustments
@param ist      reference input stream to copy timings from
@param copy_tb  define from where the stream codec timebase needs to be imported

                avformat_alloc_context().
                Its \ref AVFormatContext.oformat "oformat" field must be set
                to the desired output format;
                Its \ref AVFormatContext.pb "pb" field must be set to an
                already opened ::AVIOContext.
@param options  An ::AVDictionary filled with AVFormatContext and
                muxer-private options.
                On return this parameter will be destroyed and replaced with
                a dict containing options that were not found. May be NULL.

@retval AVSTREAM_INIT_IN_WRITE_HEADER On success, if the codec had not already been
                                      fully initialized in avformat_init_output().
@retval AVSTREAM_INIT_IN_INIT_OUTPUT  On success, if the codec had already been fully
                                      initialized in avformat_init_output().

func AVFrameApplyCropping ¶

func AVFrameApplyCropping(frame *AVFrame, flags int) (int, error)

AVFrameApplyCropping wraps av_frame_apply_cropping.

Crop the given video AVFrame according to its crop_left/crop_top/crop_right/
crop_bottom fields. If cropping is successful, the function will adjust the
data pointers and the width/height fields, and set the crop fields to 0.

In all cases, the cropping boundaries will be rounded to the inherent
alignment of the pixel format. In some cases, such as for opaque hwaccel
formats, the left/top cropping is ignored. The crop fields are set to 0 even
if the cropping was rounded or ignored.

@param frame the frame which should be cropped
@param flags Some combination of AV_FRAME_CROP_* flags, or 0.

@return >= 0 on success, a negative AVERROR on error. If the cropping fields
were invalid, AVERROR(ERANGE) is returned, and nothing is changed.

func AVFrameCopy ¶

func AVFrameCopy(dst *AVFrame, src *AVFrame) (int, error)

AVFrameCopy wraps av_frame_copy.

Copy the frame data from src to dst.

This function does not allocate anything, dst must be already initialized and
allocated with the same parameters as src.

This function only copies the frame data (i.e. the contents of the data /
extended data arrays), not any other properties.

@return >= 0 on success, a negative AVERROR on error.

func AVFrameCopyProps ¶

func AVFrameCopyProps(dst *AVFrame, src *AVFrame) (int, error)

AVFrameCopyProps wraps av_frame_copy_props.

Copy only "metadata" fields from src to dst.

Metadata for the purpose of this function are those fields that do not affect
the data layout in the buffers.  E.g. pts, sample rate (for audio) or sample
aspect ratio (for video), but not width/height or channel layout.
Side data is also copied.

func AVFrameFree ¶

func AVFrameFree(frame **AVFrame)

AVFrameFree wraps av_frame_free.

Free the frame and any dynamically allocated objects in it,
e.g. extended_data. If the frame is reference counted, it will be
unreferenced first.

@param frame frame to be freed. The pointer will be set to NULL.

func AVFrameGetBuffer ¶

func AVFrameGetBuffer(frame *AVFrame, align int) (int, error)

AVFrameGetBuffer wraps av_frame_get_buffer.

Allocate new buffer(s) for audio or video data.

The following fields must be set on frame before calling this function:
- format (pixel format for video, sample format for audio)
- width and height for video
- nb_samples and ch_layout for audio

This function will fill AVFrame.data and AVFrame.buf arrays and, if
necessary, allocate and fill AVFrame.extended_data and AVFrame.extended_buf.
For planar formats, one buffer will be allocated for each plane.

@warning: if frame already has been allocated, calling this function will
          leak memory. In addition, undefined behavior can occur in certain
          cases.

@param frame frame in which to store the new buffers.
@param align Required buffer size alignment. If equal to 0, alignment will be
             chosen automatically for the current CPU. It is highly
             recommended to pass 0 here unless you know what you are doing.

@return 0 on success, a negative AVERROR on error.

func AVFrameIsWritable ¶

func AVFrameIsWritable(frame *AVFrame) (int, error)

AVFrameIsWritable wraps av_frame_is_writable.

Check if the frame data is writable.

@return A positive value if the frame data is writable (which is true if and
only if each of the underlying buffers has only one reference, namely the one
stored in this frame). Return 0 otherwise.

If 1 is returned the answer is valid until av_buffer_ref() is called on any
of the underlying AVBufferRefs (e.g. through av_frame_ref() or directly).

@see av_frame_make_writable(), av_buffer_is_writable()

func AVFrameMakeWritable ¶

func AVFrameMakeWritable(frame *AVFrame) (int, error)

AVFrameMakeWritable wraps av_frame_make_writable.

Ensure that the frame data is writable, avoiding data copy if possible.

Do nothing if the frame is writable, allocate new buffers and copy the data
if it is not. Non-refcounted frames behave as non-writable, i.e. a copy
is always made.

@return 0 on success, a negative AVERROR on error.

@see av_frame_is_writable(), av_buffer_is_writable(),
av_buffer_make_writable()

func AVFrameMoveRef ¶

func AVFrameMoveRef(dst *AVFrame, src *AVFrame)

AVFrameMoveRef wraps av_frame_move_ref.

Move everything contained in src to dst and reset src.

@warning: dst is not unreferenced, but directly overwritten without reading
          or deallocating its contents. Call av_frame_unref(dst) manually
          before calling this function to ensure that no memory is leaked.

func AVFrameRef ¶

func AVFrameRef(dst *AVFrame, src *AVFrame) (int, error)

AVFrameRef wraps av_frame_ref.

Set up a new reference to the data described by the source frame.

Copy frame properties from src to dst and create a new reference for each
AVBufferRef from src.

If src is not reference counted, new buffers are allocated and the data is
copied.

@warning: dst MUST have been either unreferenced with av_frame_unref(dst),
          or newly allocated with av_frame_alloc() before calling this
          function, or undefined behavior will occur.

@return 0 on success, a negative AVERROR on error

func AVFrameRemoveSideData ¶

func AVFrameRemoveSideData(frame *AVFrame, _type AVFrameSideDataType)

AVFrameRemoveSideData wraps av_frame_remove_side_data.

func AVFrameReplace(dst *AVFrame, src *AVFrame) (int, error)

AVFrameReplace wraps av_frame_replace.

Ensure the destination frame refers to the same data described by the source
frame, either by creating a new reference for each AVBufferRef from src if
they differ from those in dst, by allocating new buffers and copying data if
src is not reference counted, or by unrefencing it if src is empty.

Frame properties on dst will be replaced by those from src.

@return 0 on success, a negative AVERROR on error. On error, dst is
        unreferenced.

func AVFrameUnref ¶

@see av_freep()

func AVFreep ¶

func AVFreep(ptr unsafe.Pointer)

AVFreep wraps av_freep.

Free a memory block which has been allocated with a function of av_malloc()
or av_realloc() family, and set the pointer pointing to it to `NULL`.

@code{.c}
uint8_t *buf = av_malloc(16);
av_free(buf);
buf now contains a dangling pointer to freed memory, and accidental
dereference of buf will result in a use-after-free, which may be a
security risk.

uint8_t *buf = av_malloc(16);
av_freep(&buf);
buf is now NULL, and accidental dereference will only result in a
NULL-pointer dereference.
@endcode

@param ptr Pointer to the pointer to the memory block which should be freed
@note `*ptr = NULL` is safe and leads to no action.
@see av_free()

func AVGcd ¶

func AVHWDeviceCtxCreate ¶ added in v0.5.0

func AVHWDeviceCtxCreate(deviceCtx **AVBufferRef, _type AVHWDeviceType, device *CStr, opts *AVDictionary, flags int) (int, error)

AVHWDeviceCtxCreate wraps av_hwdevice_ctx_create.

Open a device of the specified type and create an AVHWDeviceContext for it.

This is a convenience function intended to cover the simple cases. Callers
who need to fine-tune device creation/management should open the device
manually and then wrap it in an AVHWDeviceContext using
av_hwdevice_ctx_alloc()/av_hwdevice_ctx_init().

The returned context is already initialized and ready for use, the caller
should not call av_hwdevice_ctx_init() on it. The user_opaque/free fields of
the created AVHWDeviceContext are set by this function and should not be
touched by the caller.

@param device_ctx On success, a reference to the newly-created device context
                  will be written here. The reference is owned by the caller
                  and must be released with av_buffer_unref() when no longer
                  needed. On failure, NULL will be written to this pointer.
@param type The type of the device to create.
@param device A type-specific string identifying the device to open.
@param opts A dictionary of additional (type-specific) options to use in
            opening the device. The dictionary remains owned by the caller.
@param flags currently unused

@return 0 on success, a negative AVERROR code on failure.

func AVHWDeviceCtxCreateDerived ¶ added in v0.5.0

func AVHWDeviceCtxCreateDerived(dstCtx **AVBufferRef, _type AVHWDeviceType, srcCtx *AVBufferRef, flags int) (int, error)

AVHWDeviceCtxCreateDerived wraps av_hwdevice_ctx_create_derived.

Create a new device of the specified type from an existing device.

If the source device is a device of the target type or was originally
derived from such a device (possibly through one or more intermediate
devices of other types), then this will return a reference to the
existing device of the same type as is requested.

Otherwise, it will attempt to derive a new device from the given source
device.  If direct derivation to the new type is not implemented, it will
attempt the same derivation from each ancestor of the source device in
turn looking for an implemented derivation method.

@param dst_ctx On success, a reference to the newly-created
               AVHWDeviceContext.
@param type    The type of the new device to create.

AVHWDeviceCtxCreateDerivedOpts wraps av_hwdevice_ctx_create_derived_opts.

Create a new device of the specified type from an existing device.

This function performs the same action as av_hwdevice_ctx_create_derived,

@param dst_ctx On success, a reference to the newly-created
               AVHWDeviceContext.
@param type    The type of the new device to create.
@param src_ctx A reference to an existing AVHWDeviceContext which will be
               used to create the new device.

func AVHWFrameCtxCreateDerived(derivedFrameCtx **AVBufferRef, format AVPixelFormat, derivedDeviceCtx *AVBufferRef, sourceFrameCtx *AVBufferRef, flags int) (int, error)

AVHWFrameCtxCreateDerived wraps av_hwframe_ctx_create_derived.

Create and initialise an AVHWFramesContext as a mapping of another existing
AVHWFramesContext on a different device.

av_hwframe_ctx_init() should not be called after this.

@param derived_frame_ctx  On success, a reference to the newly created
                          AVHWFramesContext.
@param format             The AVPixelFormat for the derived context.
@param derived_device_ctx A reference to the device to create the new
                          AVHWFramesContext on.
@param source_frame_ctx   A reference to an existing AVHWFramesContext
                          which will be mapped to the derived context.

              mapping parameters to apply to frames which are allocated
              in the derived device.
@return       Zero on success, negative AVERROR code on failure.

func AVHWFrameCtxInit ¶ added in v0.5.0

func AVHWFrameCtxInit(ref *AVBufferRef) (int, error)

func AVHWFrameGetBuffer ¶ added in v0.5.0

func AVHWFrameGetBuffer(hwframeCtx *AVBufferRef, frame *AVFrame, flags int) (int, error)

AVHWFrameGetBuffer wraps av_hwframe_get_buffer.

Allocate a new frame attached to the given AVHWFramesContext.

@param hwframe_ctx a reference to an AVHWFramesContext
@param frame an empty (freshly allocated or unreffed) frame to be filled with
             newly allocated buffers.
@param flags currently unused, should be set to zero
@return 0 on success, a negative AVERROR code on failure

func AVHWFrameMap ¶ added in v0.5.0

func AVHWFrameMap(dst *AVFrame, src *AVFrame, flags int) (int, error)

AVHWFrameMap wraps av_hwframe_map.

Map a hardware frame.

This has a number of different possible effects, depending on the format
and origin of the src and dst frames.  On input, src should be a usable
frame with valid buffers and dst should be blank (typically as just created
by av_frame_alloc()).  src should have an associated hwframe context, and
dst may optionally have a format and associated hwframe context.

If src was created by mapping a frame from the hwframe context of dst,
then this function undoes the mapping - dst is replaced by a reference to
the frame that src was originally mapped from.

If both src and dst have an associated hwframe context, then this function
attempts to map the src frame from its hardware context to that of dst and
then fill dst with appropriate data to be usable there.  This will only be
possible if the hwframe contexts and associated devices are compatible -
given compatible devices, av_hwframe_ctx_create_derived() can be used to
create a hwframe context for dst in which mapping should be possible.

If src has a hwframe context but dst does not, then the src frame is
mapped to normal memory and should thereafter be usable as a normal frame.
If the format is set on dst, then the mapping will attempt to create dst
with that format and fail if it is not possible.  If format is unset (is
AV_PIX_FMT_NONE) then dst will be mapped with whatever the most appropriate
format to use is (probably the sw_format of the src hwframe context).

A return value of AVERROR(ENOSYS) indicates that the mapping is not
possible with the given arguments and hwframe setup, while other return
values indicate that it failed somehow.

On failure, the destination frame will be left blank, except for the
hw_frames_ctx/format fields thay may have been set by the caller - those will
be preserved as they were.

@param dst Destination frame, to contain the mapping.
@param src Source frame, to be mapped.
@param flags Some combination of AV_HWFRAME_MAP_* flags.
@return Zero on success, negative AVERROR code on failure.

func AVHWFrameTransferData ¶ added in v0.5.0

func AVHWFrameTransferData(dst *AVFrame, src *AVFrame, flags int) (int, error)

AVHWFrameTransferData wraps av_hwframe_transfer_data.

Copy data to or from a hw surface. At least one of dst/src must have an
AVHWFramesContext attached.

If src has an AVHWFramesContext attached, then the format of dst (if set)
must use one of the formats returned by av_hwframe_transfer_get_formats(src,
AV_HWFRAME_TRANSFER_DIRECTION_FROM).
If dst has an AVHWFramesContext attached, then the format of src must use one
of the formats returned by av_hwframe_transfer_get_formats(dst,
AV_HWFRAME_TRANSFER_DIRECTION_TO)

dst may be "clean" (i.e. with data/buf pointers unset), in which case the
data buffers will be allocated by this function using av_frame_get_buffer().
If dst->format is set, then this format will be used, otherwise (when
dst->format is AV_PIX_FMT_NONE) the first acceptable format will be chosen.

The two frames must have matching allocated dimensions (i.e. equal to
AVHWFramesContext.width/height), since not all device types support
transferring a sub-rectangle of the whole surface. The display dimensions
(i.e. AVFrame.width/height) may be smaller than the allocated dimensions, but
also have to be equal for both frames. When the display dimensions are
smaller than the allocated dimensions, the content of the padding in the
destination frame is unspecified.

@param dst the destination frame. dst is not touched on failure.
@param src the source frame.
@param flags currently unused, should be set to zero
@return 0 on success, a negative AVERROR error code on failure.

func AVHexDumpLog ¶

func AVHexDumpLog(avcl unsafe.Pointer, level int, buf unsafe.Pointer, size int)

func AVIOCheck ¶

func AVIOCheck(url *CStr, flags int) (int, error)

AVIOCheck wraps avio_check.

Return AVIO_FLAG_* access flags corresponding to the access permissions
of the resource in url, or a negative value corresponding to an
AVERROR code in case of failure. The returned access flags are
masked by the value in flags.

@note This function is intrinsically unsafe, in the sense that the
checked resource may change its existence or permission status from
one call to another. Thus you should not trust the returned value,
unless you are sure that no other processes are accessing the
checked resource.

func AVIOClose ¶

func AVIOClose(s *AVIOContext) (int, error)

AVIOClose wraps avio_close.

a NULL character was encountered, maxlen bytes have been read, or nothing
more can be read from pb. The result is guaranteed to be NULL-terminated, it
will be truncated if buf is too small.
Note that the string is not interpreted or validated in any way, it
might get truncated in the middle of a sequence for multi-byte encodings.

@return number of bytes read (is always <= maxlen).
If reading ends on EOF or error, the return value will be one more than
bytes actually read.

func AVIOHandshake ¶

func AVIOHandshake(c *AVIOContext) (int, error)

AVIOHandshake wraps avio_handshake.

Perform one step of the protocol handshake to accept a new client.
This function must be called on a client returned by avio_accept() before
using it as a read/write context.
It is separate from avio_accept() because it may block.
A step of the handshake is defined by places where the application may
decide to change the proceedings.
For example, on a protocol with a request header and a reply header, each
one can constitute a step because the application may use the parameters
from the request to change parameters in the reply; or each individual
chunk of the request can constitute a step.
If the handshake is already finished, avio_handshake() does nothing and
returns 0 immediately.

@param  c the client context to perform the handshake on
@return   0   on a complete and successful handshake
          > 0 if the handshake progressed, but is not complete
          < 0 for an AVERROR code

@param h IO context from which to call the seek function pointers
@param stream_index The stream index that the timestamp is relative to.
       If stream_index is (-1) the timestamp should be in AV_TIME_BASE
       units from the beginning of the presentation.
       If a stream_index >= 0 is used and the protocol does not support
       seeking based on component streams, the call will fail.
@param timestamp timestamp in AVStream.time_base units
       or if there is no stream specified then in AV_TIME_BASE units.
@param flags Optional combination of AVSEEK_FLAG_BACKWARD, AVSEEK_FLAG_BYTE
       and AVSEEK_FLAG_ANY. The protocol may silently ignore

@return  length of the list, in elements, not counting the terminator

func AVInterleavedWriteFrame ¶

func AVInterleavedWriteFrame(s *AVFormatContext, pkt *AVPacket) (int, error)

AVInterleavedWriteFrame wraps av_interleaved_write_frame.

Write a packet to an output media file ensuring correct interleaving.

This function will buffer the packets internally as needed to make sure the
packets in the output file are properly interleaved, usually ordered by
increasing dts. Callers doing their own interleaving should call
av_write_frame() instead of this function.

Using this function instead of av_write_frame() can give muxers advance
knowledge of future packets, improving e.g. the behaviour of the mp4
muxer for VFR content in fragmenting mode.

@param s media file handle
@param pkt The packet containing the data to be written.
           <br>
           If the packet is reference-counted, this function will take
           ownership of this reference and unreference it later when it sees
           fit. If the packet is not reference-counted, libavformat will
           make a copy.
           The returned packet will be blank (as if returned from
           av_packet_alloc()), even on error.
           <br>
           This parameter can be NULL (at any time, not just at the end), to
           flush the interleaving queues.
           <br>
           Packet's @ref AVPacket.stream_index "stream_index" field must be
           set to the index of the corresponding stream in @ref
           AVFormatContext.streams "s->streams".
           <br>
           The timestamps (@ref AVPacket.pts "pts", @ref AVPacket.dts "dts")
           must be set to correct values in the stream's timebase (unless the
           output format is flagged with the AVFMT_NOTIMESTAMPS flag, then
           they can be set to AV_NOPTS_VALUE).
           The dts for subsequent packets in one stream must be strictly
           increasing (unless the output format is flagged with the
           AVFMT_TS_NONSTRICT, then they merely have to be nondecreasing).
           @ref AVPacket.duration "duration" should also be set if known.

@return 0 on success, a negative AVERROR on error.

@see av_write_frame(), AVFormatContext.max_interleave_delta

AVInterleavedWriteUncodedFrame wraps av_interleaved_write_uncoded_frame.

Write an uncoded frame to an output media file.

If the muxer supports it, this function makes it possible to write an AVFrame
structure directly, without encoding it into a packet.
It is mostly useful for devices and similar special muxers that use raw
video or PCM data and will not serialize it into a byte stream.

To test whether it is possible to use it with a given muxer and stream,
use av_write_uncoded_frame_query().

The caller gives up ownership of the frame and must not access it
afterwards.

@return  >=0 for success, a negative code on error

scalar. Behavior with more than one scalar and +- infix operators
is undefined.
If the field is of a flags type, it has to be a sequence of numeric
scalars or named flags separated by '+' or '-'. Prefixing a flag

key=value parameters. Values containing ':' special characters must be
escaped.
@param search_flags flags passed to av_opt_find2. I.e. if AV_OPT_SEARCH_CHILDREN

func AVReadFrame ¶

func AVReadFrame(s *AVFormatContext, pkt *AVPacket) (int, error)

AVReadFrame wraps av_read_frame.

Return the next frame of a stream.
This function returns what is stored in the file, and does not validate
that what is there are valid frames for the decoder. It will split what is
stored in the file into frames and return one for each call. It will not
omit invalid data between valid frames so as to give the decoder the maximum
information possible for decoding.

On success, the returned packet is reference-counted (pkt->buf is set) and
valid indefinitely. The packet must be freed with av_packet_unref() when
it is no longer needed. For video, the packet contains exactly one frame.
For audio, it contains an integer number of frames if each frame has
a known fixed size (e.g. PCM or ADPCM data). If the audio frames have
a variable size (e.g. MPEG audio), then it contains one frame.

pkt->pts, pkt->dts and pkt->duration are always set to correct
values in AVStream.time_base units (and guessed if the format cannot
provide them). pkt->pts can be AV_NOPTS_VALUE if the video format
has B-frames, so it is better to rely on pkt->dts if you do not
decompress the payload.

@return 0 if OK, < 0 on error or end of file. On error, pkt will be blank
        (as if it came from av_packet_alloc()).

  leak with the classic
  @code{.c}
  buf = realloc(buf);

packets if the format requires it. Callers that want libavformat to handle
the interleaving should call av_interleaved_write_frame() instead of this
function.

@param s media file handle
@param pkt The packet containing the data to be written. Note that unlike
           av_interleaved_write_frame(), this function does not take

           The timestamps (@ref AVPacket.pts "pts", @ref AVPacket.dts "dts")
           must be set to correct values in the stream's timebase (unless the
           output format is flagged with the AVFMT_NOTIMESTAMPS flag, then
           they can be set to AV_NOPTS_VALUE).

type AVChannelCustom ¶

type AVChannelCustom struct {
	// contains filtered or unexported fields
}

type AVChannelLayout ¶

type AVChannelLayout struct {
	// contains filtered or unexported fields
}

AVChannelLayout wraps AVChannelLayout.

An AVChannelLayout holds information about the channel layout of audio data.

A channel layout here is defined as a set of channels ordered in a specific
way (unless the channel order is AV_CHANNEL_ORDER_UNSPEC, in which case an
AVChannelLayout carries only the channel count).
All orders may be treated as if they were AV_CHANNEL_ORDER_UNSPEC by
ignoring everything but the channel count, as long as av_channel_layout_check()
considers they are valid.

Unlike most structures in FFmpeg, sizeof(AVChannelLayout) is a part of the
public ABI and may be used by the caller. E.g. it may be allocated on stack
or embedded in caller-defined structs.

AVChannelLayout can be initialized as follows:
- default initialization with {0}, followed by setting all used fields
  correctly;
- by assigning one of the predefined AV_CHANNEL_LAYOUT_* initializers;
- with a constructor function, such as av_channel_layout_default(),
  av_channel_layout_from_mask() or av_channel_layout_from_string().

The channel layout must be unitialized with av_channel_layout_uninit()

Copying an AVChannelLayout via assigning is forbidden,
av_channel_layout_copy() must be used instead (and its return value should
be checked)

func (*AVCodecContext) ApplyCropping ¶

func (s *AVCodecContext) ApplyCropping() int

ApplyCropping gets the apply_cropping field.

Video decoding only. Certain video codecs support cropping, meaning that
only a sub-rectangle of the decoded frame is intended for display.  This
option controls how cropping is handled by libavcodec.

When set to 1 (the default), libavcodec will apply cropping internally.
I.e. it will modify the output frame width/height fields and offset the
data pointers (only by as much as possible while preserving alignment, or
by the full amount if the AV_CODEC_FLAG_UNALIGNED flag is set) so that
the frames output by the decoder refer only to the cropped area. The
crop_* fields of the output frames will be zero.

When set to 0, the width/height fields of the output frames will be set
to the coded dimensions and the crop_* fields will describe the cropping
rectangle. Applying the cropping is left to the caller.

@warning When hardware acceleration with opaque output frames is used,
libavcodec is unable to apply cropping from the top/left border.

@note when this option is set to zero, the width/height fields of the
AVCodecContext and output AVFrames have different meanings. The codec
context fields store display dimensions (with the coded dimensions in
coded_width/height), while the frame fields store the coded dimensions
(with the display dimensions being determined by the crop_* fields).

This should be used if either the codec device does not require
hardware frames or any that are used are to be allocated internally by
libavcodec.  If the user wishes to supply any of the frames used as
encoder input or decoder output then hw_frames_ctx should be used
instead.  When hw_frames_ctx is set in get_format() for a decoder, this
field will be ignored while decoding the associated stream segment, but
may again be used on a following one after another get_format() call.

For both encoders and decoders this field should be set before
avcodec_open2() is called and must not be written to thereafter.

Note that some decoders may require this field to be set initially in

            callback. The previous reference (if any) will always be
            unreffed by libavcodec before the get_format() call.

            If the default get_buffer2() is used with a hwaccel pixel
            format, then this AVHWFramesContext will be used for
            allocating the frame buffers.

- encoding: For hardware encoders configured to use a hwaccel pixel
            format, this field should be set by the caller to a reference
            to the AVHWFramesContext describing input frames.
            AVHWFramesContext.format must be equal to
            AVCodecContext.pix_fmt.

signal hwaccel-specific data to the codec. The struct pointed to by this
pointer is hwaccel-dependent and defined in the respective header. Please
refer to the FFmpeg HW accelerator documentation to know how to fill
this.

In most cases this field is optional - the necessary information may also
be provided to libavcodec through @ref hw_frames_ctx or @ref
hw_device_ctx (see avcodec_get_hw_config()). However, in some cases it
may be the only method of signalling some (optional) information.

The struct and its contents are owned by the caller.

- encoding: May be set by the caller before avcodec_open2(). Must remain
            valid until avcodec_free_context().
- decoding: May be set by the caller in the get_format() callback.

            including any added padding.  E.g. if the timebase is
            1/samplerate and the timestamp of the first input sample is

SetApplyCropping sets the apply_cropping field.

Video decoding only. Certain video codecs support cropping, meaning that
only a sub-rectangle of the decoded frame is intended for display.  This
option controls how cropping is handled by libavcodec.

When set to 1 (the default), libavcodec will apply cropping internally.
I.e. it will modify the output frame width/height fields and offset the
data pointers (only by as much as possible while preserving alignment, or
by the full amount if the AV_CODEC_FLAG_UNALIGNED flag is set) so that
the frames output by the decoder refer only to the cropped area. The
crop_* fields of the output frames will be zero.

to the coded dimensions and the crop_* fields will describe the cropping
rectangle. Applying the cropping is left to the caller.

@warning When hardware acceleration with opaque output frames is used,
libavcodec is unable to apply cropping from the top/left border.

@note when this option is set to zero, the width/height fields of the
AVCodecContext and output AVFrames have different meanings. The codec
context fields store display dimensions (with the coded dimensions in
coded_width/height), while the frame fields store the coded dimensions
(with the display dimensions being determined by the crop_* fields).

If there are multiple such fields in a container then the demuxer should choose the one
which maximizes the information about the used codec.
If the codec tag field in a container is larger than 32 bits then the demuxer should
remap the longer ID to 32 bits with a table or other structure. Alternatively a new

caller and afterwards owned (and freed) by libavcodec.

This should be used if either the codec device does not require
hardware frames or any that are used are to be allocated internally by
libavcodec.  If the user wishes to supply any of the frames used as
encoder input or decoder output then hw_frames_ctx should be used
instead.  When hw_frames_ctx is set in get_format() for a decoder, this
field will be ignored while decoding the associated stream segment, but
may again be used on a following one after another get_format() call.

For both encoders and decoders this field should be set before
avcodec_open2() is called and must not be written to thereafter.

Note that some decoders may require this field to be set initially in
order to support hw_frames_ctx at all - in that case, all frames
contexts used must be created on the same device.

            callback. The previous reference (if any) will always be
            unreffed by libavcodec before the get_format() call.

            If the default get_buffer2() is used with a hwaccel pixel
            format, then this AVHWFramesContext will be used for
            allocating the frame buffers.

- encoding: For hardware encoders configured to use a hwaccel pixel
            format, this field should be set by the caller to a reference
            to the AVHWFramesContext describing input frames.
            AVHWFramesContext.format must be equal to
            AVCodecContext.pix_fmt.

For some hardware acceleration methods, the caller may use this field to
signal hwaccel-specific data to the codec. The struct pointed to by this
pointer is hwaccel-dependent and defined in the respective header. Please
refer to the FFmpeg HW accelerator documentation to know how to fill
this.

In most cases this field is optional - the necessary information may also
be provided to libavcodec through @ref hw_frames_ctx or @ref
hw_device_ctx (see avcodec_get_hw_config()). However, in some cases it
may be the only method of signalling some (optional) information.

The struct and its contents are owned by the caller.

- encoding: May be set by the caller before avcodec_open2(). Must remain
            valid until avcodec_free_context().
- decoding: May be set by the caller in the get_format() callback.

- encoding: Set AVCodecContext.framerate instead

func (*AVCodecContext) TimeBase ¶

func (s *AVCodecContext) TimeBase() *AVRational

This is the fundamental unit of time (in seconds) in terms
of which frame timestamps are represented. For fixed-fps content,

for video. 1/time_base is not the average frame rate if the frame rate is not
constant.

Like containers, elementary streams also can store timestamps, 1/time_base
is the unit in which these timestamps are specified.
As example of such codec time base see ISO/IEC 14496-2:2001(E)

- decoding: May be set by the user before opening the decoder if known e.g.
            from the container. Some decoders will require the dimensions
            to be set by the caller. During decoding, the decoder may

Two encoders with the same ID can encode compatible streams.
There may be slight deviations from the principle due to implementation
details.

If you add a codec ID to this list, add it so that
1. no value of an existing codec ID changes (that would break ABI),
2. it is as close as possible to similar codecs

After adding new codec IDs, do not forget to add an entry to the codec
descriptor list and bump libavcodec minor version.

the actual coded bitstream.

This could be for example 4 for ADPCM
For PCM formats this matches bits_per_raw_sample
Can be 0

func (*AVCodecParameters) BitsPerRawSample ¶

func (s *AVCodecParameters) BitsPerRawSample() int

BitsPerRawSample gets the bits_per_raw_sample field.

This is the number of valid bits in each output sample. If the
sample format has more bits, the least significant bits are additional
padding bits, which are always 0. Use right shifts to reduce the sample
to its actual size. For example, audio formats with 24 bit samples will
have bits_per_raw_sample set to 24, and format set to AV_SAMPLE_FMT_S32.
To get the original sample use "(int32_t)sample >> 8"."

For ADPCM this might be 12 or 16 or similar
Can be 0

func (*AVCodecParameters) BlockAlign ¶

type AVColorRange ¶

type AVColorRange C.enum_AVColorRange

AVColorRange wraps AVColorRange.

Visual content value range.

These values are based on definitions that can be found in multiple
specifications, such as ITU-T BT.709 (3.4 - Quantization of RGB, luminance
and colour-difference signals), ITU-T BT.2020 (Table 5 - Digital
Representation) as well as ITU-T BT.2100 (Table 9 - Digital 10- and 12-bit
integer representation). At the time of writing, the BT.2100 one is
recommended, as it also defines the full range representation.

Common definitions:
  - For RGB and luma planes such as Y in YCbCr and I in ICtCp,
    'E' is the original value in range of 0.0 to 1.0.
  - For chroma planes such as Cb,Cr and Ct,Cp, 'E' is the original
    value in range of -0.5 to 0.5.
  - 'n' is the output bit depth.
  - For additional definitions such as rounding and clipping to valid n
    bit unsigned integer range, please refer to BT.2100 (Table 9).

type AVFrame ¶

type AVFrame struct {
	// contains filtered or unexported fields
}

AVFrame wraps AVFrame.

This structure describes decoded (raw) audio or video data.

AVFrame must be allocated using av_frame_alloc(). Note that this only
allocates the AVFrame itself, the buffers for the data must be managed
through other means (see below).
AVFrame must be freed with av_frame_free().

AVFrame is typically allocated once and then reused multiple times to hold
different data (e.g. a single AVFrame to hold frames received from a
decoder). In such a case, av_frame_unref() will free any references held by
the frame and reset it to its original clean state before it
is reused again.

The data described by an AVFrame is usually reference counted through the
AVBuffer API. The underlying buffer references are stored in AVFrame.buf /
AVFrame.extended_buf. An AVFrame is considered to be reference counted if at
least one reference is set, i.e. if AVFrame.buf[0] != NULL. In such a case,
every single data plane must be contained in one of the buffers in
AVFrame.buf or AVFrame.extended_buf.
There may be a single buffer for all the data, or one separate buffer for
each plane, or anything in between.

sizeof(AVFrame) is not a part of the public ABI, so new fields may be added
to the end with a minor bump.

Fields can be accessed through AVOptions, the name string used, matches the
C structure field name for fields accessible through AVOptions. The AVClass
for AVFrame can be obtained from avcodec_get_frame_class()

func AVFrameAlloc ¶

AVFrameAlloc wraps av_frame_alloc.

Allocate an AVFrame and set its fields to default values.  The resulting
struct must be freed using av_frame_free().

@return An AVFrame filled with default values or NULL on failure.

@note this only allocates the AVFrame itself, not the data buffers. Those
must be allocated through other means, e.g. with av_frame_get_buffer() or
manually.

func AVFrameClone ¶

func AVFrameClone(src *AVFrame) *AVFrame

extended_buf. This array must be filled contiguously -- if buf[i] is
non-NULL then buf[j] must also be non-NULL for all j < i.

There may be at most one AVBuffer per data plane, so for video this array
always contains all the references. For planar audio with more than
AV_NUM_DATA_POINTERS channels, there may be more buffers than can fit in
this array. Then the extra AVBufferRef pointers are stored in the
extended_buf array.

the decoder reorders values as needed and sets AVFrame.reordered_opaque
to exactly one of the values provided by the user through AVCodecContext.reordered_opaque

@deprecated Use AV_CODEC_FLAG_COPY_OPAQUE instead

func (*AVFrame) SetRepeatPict ¶

func (s *AVFrame) SetRepeatPict(value int)

SetRepeatPict sets the repeat_pict field.

Number of fields in this frame which should be repeated, i.e. the total
duration of this frame should be repeat_pict + 2 normal field durations.

For interlaced frames this field may be set to 1, which signals that this
frame should be presented as 3 fields: beginning with the first field (as
determined by AV_FRAME_FLAG_TOP_FIELD_FIRST being set or not), followed
by the second field, and then the first field again.

For progressive frames this field may be set to a multiple of 2, which
signals that this frame's duration should be (repeat_pict + 2) / 2
normal frame durations.

@note This field is computed from MPEG2 repeat_first_field flag and its
associated flags, H.264 pic_struct from picture timing SEI, and
their analogues in other codecs. Typically it should only be used when
higher-layer timing information is not available.

this struct will (if possible) wrap the state that is common to both encoding
and decoding and from which specific instances of encoders or decoders can be
derived.

This struct is reference-counted with the AVBuffer mechanism. The
av_hwdevice_ctx_alloc() constructor yields a reference, whose data field
points to the actual AVHWDeviceContext. Further objects derived from
AVHWDeviceContext (such as AVHWFramesContext, describing a frame pool with
specific properties) will hold an internal reference to it. After all the
references are released, the AVHWDeviceContext itself will be freed,

type AVPacket ¶

type AVPacket struct {
	// contains filtered or unexported fields
}

AVPacket wraps AVPacket.

This structure stores compressed data. It is typically exported by demuxers
and then passed as input to decoders, or received as output from encoders and
then passed to muxers.

For video, it should typically contain one compressed frame. For audio it may
contain several compressed frames. Encoders are allowed to output empty
packets, with no compressed data, containing only side data
(e.g. to update some stream parameters at the end of encoding).

The semantics of data ownership depends on the buf field.
If it is set, the packet data is dynamically allocated and is
valid indefinitely until a call to av_packet_unref() reduces the
reference count to 0.

If the buf field is not set av_packet_ref() would make a copy instead
of increasing the reference count.

The side data is always allocated with av_malloc(), copied by
av_packet_ref() and freed by av_packet_unref().

sizeof(AVPacket) being a part of the public ABI is deprecated. once
av_init_packet() is removed, new packets will only be able to be allocated
with av_packet_alloc(), and new fields may be added to the end of the struct
with a minor bump.

@see av_packet_alloc
@see av_packet_ref
@see av_packet_unref

func AVPacketAlloc ¶

func AVPacketAlloc() *AVPacket

AVPacketAlloc wraps av_packet_alloc.

Allocate an AVPacket and set its fields to default values.  The resulting
struct must be freed using av_packet_free().

@note this only allocates the AVPacket itself, not the data buffers. Those
must be allocated through other means such as av_new_packet.

@see av_new_packet

func AVPacketClone ¶

func AVPacketClone(src *AVPacket) *AVPacket

AVPacketClone wraps av_packet_clone.

Create a new packet that references the same data as src.

This is a shortcut for av_packet_alloc()+av_packet_ref().

@return newly created AVPacket on success, NULL on error.

@see av_packet_alloc
@see av_packet_ref

type AVPacketSideData ¶

type AVPacketSideData struct {
	// contains filtered or unexported fields
}

AVPacketSideData wraps AVPacketSideData.

This structure stores auxiliary information for decoding, presenting, or
otherwise processing the coded stream. It is typically exported by demuxers
and encoders and can be fed to decoders and muxers either in a per packet
basis, or as global side data (applying to the entire coded stream).

Global side data is handled as follows:
- During demuxing, it may be exported through
  @ref AVStream.codecpar.side_data "AVStream's codec parameters", which can
  then be passed as input to decoders through the
  @ref AVCodecContext.coded_side_data "decoder context's side data", for
  initialization.
- For muxing, it can be fed through @ref AVStream.codecpar.side_data
  "AVStream's codec parameters", typically  the output of encoders through
  the @ref AVCodecContext.coded_side_data "encoder context's side data", for
  initialization.

Packet specific side data is handled as follows:
- During demuxing, it may be exported through @ref AVPacket.side_data
  "AVPacket's side data", which can then be passed as input to decoders.
- For muxing, it can be fed through @ref AVPacket.side_data "AVPacket's
  side data", typically the output of encoders.

Different modules may accept or export different types of side data
depending on media type and codec. Refer to @ref AVPacketSideDataType for a
list of defined types and where they may be found or used.

type AVPixelFormat ¶

type AVPixelFormat C.enum_AVPixelFormat

AVPixelFormat wraps AVPixelFormat.

Pixel format.

@note
AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
color is put together as:
 (A << 24) | (R << 16) | (G << 8) | B
This is stored as BGRA on little-endian CPU architectures and ARGB on
big-endian CPUs.

@note
If the resolution is not a multiple of the chroma subsampling factor
then the chroma plane resolution must be rounded up.

@par
When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized
image data is stored in AVFrame.data[0]. The palette is transported in
AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
also endian-specific). Note also that the individual RGB32 palette
components stored in AVFrame.data[1] should be in the range 0..255.
This is important as many custom PAL8 video codecs that were designed
to run on the IBM VGA graphics adapter use 6-bit palette components.

@par
For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like
for pal8. This palette is filled in automatically by the function
allocating the picture.

otherwise use the frame aspect ratio. This way a container setting, which is
usually easy to modify can override the coded value in the frames.

type AVRegionOfInterest ¶

type AVRegionOfInterest struct {
	// contains filtered or unexported fields
}

AVRegionOfInterest wraps AVRegionOfInterest.

Structure describing a single Region Of Interest.

When multiple regions are defined in a single side-data block, they
should be ordered from most to least important - some encoders are only
capable of supporting a limited number of distinct regions, so will have
to truncate the list.

When overlapping regions are defined, the first region containing a given
area of the frame applies.

func (*AVRegionOfInterest) Bottom ¶

Bottom gets the bottom field.

func (*AVRegionOfInterest) Left ¶

func (s *AVRegionOfInterest) Left() int

Left gets the left field.

func (*AVRegionOfInterest) Qoffset ¶

func (s *AVRegionOfInterest) Qoffset() *AVRational

Qoffset gets the qoffset field.

Quantisation offset.

Must be in the range -1 to +1.  A value of zero indicates no quality
change.  A negative value asks for better quality (less quantisation),
while a positive value asks for worse quality (greater quantisation).

The range is calibrated so that the extreme values indicate the
largest possible offset - if the rest of the frame is encoded with the
worst possible quality, an offset of -1 indicates that this region
should be encoded with the best possible quality anyway.  Intermediate
values are then interpolated in some codec-dependent way.

For example, in 10-bit H.264 the quantisation parameter varies between
-12 and 51.  A typical qoffset value of -1/10 therefore indicates that
this region should be encoded with a QP around one-tenth of the full
range better than the rest of the frame.  So, if most of the frame
were to be encoded with a QP of around 30, this region would get a QP
of around 24 (an offset of approximately -1/10 * (51 - -12) = -6.3).
An extreme value of -1 would indicate that this region should be
encoded with the best possible quality regardless of the treatment of
the rest of the frame - that is, should be encoded at a QP of -12.

func (s *AVRegionOfInterest) SetBottom(value int)

SetBottom sets the bottom field.

func (*AVRegionOfInterest) SetLeft ¶

func (s *AVRegionOfInterest) SetLeft(value int)

func (*AVRegionOfInterest) SetQoffset ¶

func (s *AVRegionOfInterest) SetQoffset(value *AVRational)

SetQoffset sets the qoffset field.

Quantisation offset.

Must be in the range -1 to +1.  A value of zero indicates no quality
change.  A negative value asks for better quality (less quantisation),
while a positive value asks for worse quality (greater quantisation).

The range is calibrated so that the extreme values indicate the
largest possible offset - if the rest of the frame is encoded with the
worst possible quality, an offset of -1 indicates that this region
should be encoded with the best possible quality anyway.  Intermediate
values are then interpolated in some codec-dependent way.

For example, in 10-bit H.264 the quantisation parameter varies between
-12 and 51.  A typical qoffset value of -1/10 therefore indicates that
this region should be encoded with a QP around one-tenth of the full
range better than the rest of the frame.  So, if most of the frame
were to be encoded with a QP of around 30, this region would get a QP
of around 24 (an offset of approximately -1/10 * (51 - -12) = -6.3).
An extreme value of -1 would indicate that this region should be
encoded with the best possible quality regardless of the treatment of
the rest of the frame - that is, should be encoded at a QP of -12.

Distance in pixels from the top edge of the frame to the top and
bottom edges and from the left edge of the frame to the left and
right edges of the rectangle defining this region of interest.

actually affected may be slightly larger for alignment or other
reasons.

func (*AVRegionOfInterest) Top ¶

func (s *AVRegionOfInterest) Top() int

Top gets the top field.

Distance in pixels from the top edge of the frame to the top and
bottom edges and from the left edge of the frame to the left and
right edges of the rectangle defining this region of interest.

  24-bit sample format even though it is a common raw audio data format.

- The floating-point formats are based on full volume being in the range
  [-1.0, 1.0]. Any values outside this range are beyond full volume level.

- The data layout as used in av_samples_fill_arrays() and elsewhere in FFmpeg
  (such as AVFrame in libavcodec) is as follows:

@par
For planar sample formats, each audio channel is in a separate data plane,
and linesize is the buffer size, in bytes, for a single plane. All data
planes must be the same size. For packed sample formats, only the first data
plane is used, and samples for each channel are interleaved. In this case,
linesize is the buffer size, in bytes, for the 1 plane.

type Array ¶

type Array[T any] struct {
	// contains filtered or unexported fields
}

Array is a helper utility for accessing arrays of FFmpeg types. You can not directly allocate this type, and you must use one of the inbuilt constructors, such as AllocAVCodecIDArray.

Arrays have no inbuilt length, matching the behaviour of C code. Getting or setting an out of bound index will lead to undefined behaviour.
