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. Similarly fields that are marked as to be only accessed by av_opt_ptr() can be reordered. This allows 2 forks to add fields without breaking compatibility with each other.

pointer to the picture/channel planes.
This might be different from the first allocated byte
Some decoders access areas outside 0,0 - width,height, please see avcodec_align_dimensions2(). Some filters and swscale can read up to 16 bytes beyond the planes, if these filters are to be used, then 16 extra bytes must be allocated.

| int AVFrame::linesize[AV_NUM_DATA_POINTERS] |
For video, size in bytes of each picture line.
For audio, size in bytes of each plane.
For audio, only linesize[0] may be set. For planar audio, each channel plane must be the same size.
For video the linesizes should be multiples of the CPUs alignment preference, this is 16 or 32 for modern desktop CPUs. Some code requires such alignment other code can be slower without correct alignment, for yet other it makes no difference.

| uint8_t** AVFrame::extended_data |
pointers to the data planes/channels.
For video, this should simply point to data[].
For planar audio, each channel has a separate data pointer, and linesize[0] contains the size of each channel buffer. For packed audio, there is just one data pointer, and linesize[0] contains the total size of the buffer for all channels.
Note: Both data and extended_data should always be set in a valid frame, but for planar audio with more channels that can fit in data, extended_data must be used in order to access all channels.

| AVBufferRef* AVFrame::buf[AV_NUM_DATA_POINTERS] |
AVBuffer references backing the data for this frame.
If all elements of this array are NULL, then this frame is not reference counted. 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.

| AVBufferRef** AVFrame::extended_buf |
For planar audio which requires more than AV_NUM_DATA_POINTERS AVBufferRef pointers, this array will hold all the references which cannot fit into AVFrame.buf.
Note that this is different from AVFrame.extended_data, which always contains all the pointers. This array only contains the extra pointers, which cannot fit into AVFrame.buf.
This array is always allocated using av_malloc() by whoever constructs the frame. It is freed in av_frame_unref().
