New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. Please use AVOptions (av_opt* / av_set/get*()) to access these fields from user applications. sizeof(AVCodecContext) must not be used outside libav*.

unsigned int AVCodecContext::codec_tag |
fourcc (LSB first, so "ABCD" -> ('D'<<24) + ('C'<<16) + ('B'<<8) + 'A').
This is used to work around some encoder bugs. A demuxer should set this to what is stored in the field used to identify the codec. 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 extra_codec_tag + size could be added but for this a clear advantage must be demonstrated first.

AVRational AVCodecContext::time_base |
This is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented.
For fixed-fps content, timebase should be 1/framerate and timestamp increments should be identically 1.

int AVCodecContext::ticks_per_frame |
For some codecs, the time base is closer to the field rate than the frame rate.
Most notably, H.264 and MPEG-2 specify time_base as half of frame duration if no telecine is used ...
Set to time_base ticks per frame. Default 1, e.g., H.264/MPEG-2 set it to 2.

int AVCodecContext::delay |
Codec delay.
Encoding: Number of frames delay there will be from the encoder input to the decoder output. (we assume the decoder matches the spec) Decoding: Number of frames delay in addition to what a standard decoder as specified in the spec would produce.
Video: Number of frames the decoded output will be delayed relative to the encoded input.
Audio: For encoding, this is the number of "priming" samples added to the beginning of the stream. The decoded output will be delayed by this many samples relative to the input to the encoder. Note that this field is purely informational and does not directly affect the pts output by the encoder, which should always be based on the actual presentation time, including any delay. For decoding, this is the number of samples the decoder needs to output before the decoder's output is valid. When seeking, you should start decoding this many samples prior to your desired seek point.

void(* AVCodecContext::draw_horiz_band)(struct AVCodecContext *s, const AVFrame *src, int offset[AV_NUM_DATA_POINTERS], int y, int type, int height) |
If non NULL, 'draw_horiz_band' is called by the libavcodec decoder to draw a horizontal band.
It improves cache usage. Not all codecs can do that. You must check the codec capabilities beforehand. When multithreading is used, it may be called from multiple threads at the same time; threads might draw different parts of the same AVFrame, or multiple AVFrames, and there is no guarantee that slices will be drawn in order. The function is also used by hardware acceleration APIs. It is called at least once during frame decoding to pass the data needed for hardware render. In that mode instead of pixel data, AVFrame points to a structure specific to the acceleration API. The application reads the structure and can change some fields to indicate progress or mark state.

int(* AVCodecContext::get_buffer2)(struct AVCodecContext *s, AVFrame *frame, int flags) |
This callback is called at the beginning of each frame to get data buffer(s) for it.
There may be one contiguous buffer for all the data or there may be a buffer per each data plane or anything in between. What this means is, you may set however many entries in buf[] you feel necessary. Each buffer must be reference-counted using the AVBuffer API (see description of buf[] below).
The following fields will be set in the frame before this callback is called:
This callback must fill the following fields in the frame:
If CODEC_CAP_DR1 is not set then get_buffer2() must call avcodec_default_get_buffer2() instead of providing buffers allocated by some other means.
Each data plane must be aligned to the maximum required by the target CPU.
Video:
If AV_GET_BUFFER_FLAG_REF is set in flags then the frame may be reused (read and/or written to if it is writable) later by libavcodec.
If CODEC_FLAG_EMU_EDGE is not set in s->flags, the buffer must contain an edge of the size returned by avcodec_get_edge_width() on all sides.
avcodec_align_dimensions2() should be used to find the required width and height, as they normally need to be rounded up to the next multiple of 16.
If frame multithreading is used and thread_safe_callbacks is set, this callback may be called from a different thread, but not from more than one at once. Does not need to be reentrant.
Audio:
Decoders request a buffer of a particular size by setting AVFrame.nb_samples prior to calling get_buffer2(). The decoder may, however, utilize only part of the buffer by setting AVFrame.nb_samples to a smaller value in the output frame.
As a convenience, av_samples_get_buffer_size() and av_samples_fill_arrays() in libavutil may be used by custom get_buffer2() functions to find the required data size and to fill data pointers and linesize. In AVFrame.linesize, only linesize[0] may be set for audio since all planes must be the same size.

If non-zero, the decoded audio and video frames returned from avcodec_decode_video2() and avcodec_decode_audio4() are reference-counted and are valid indefinitely.
The caller must free them with av_frame_unref() when they are not needed anymore. Otherwise, the decoded frames must not be freed by the caller and are only valid until the next decode call.
