This structure describes decoded (raw) audio or video data.
AVFrame must be allocated using avcodec_alloc_frame() and freed with avcodec_free_frame(). Note that this allocates only the AVFrame itself. The buffers for the data must be managed through other means.
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, avcodec_get_frame_defaults() should be used to reset the frame to its original clean state before it is reused again.
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.

This might be different from the first allocated byte

| 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 will always be set by get_buffer(), but for planar audio with more channels that can fit in data, extended_data must be used by the decoder in order to access all channels.
encoding: set by user decoding: set by AVCodecContext.get_buffer()
