main external API structure.
New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. You can use AVOptions (av_opt* / av_set/get*()) to access these fields from user applications. The name string for AVOptions options matches the associated command line parameter name and can be found in libavcodec/options_table.h The AVOption/command line parameter names differ in some cases from the C structure field names for historic reasons or brevity. sizeof(AVCodecContext) must not be used outside libav*.

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. This often, but not always is the inverse of the frame rate or field rate 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) vop_time_increment_resolution and fixed_vop_rate (fixed_vop_rate == 0 implies that it is different from the framerate)

| 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 field is unused (see initial_padding).
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.
| height | the height of the slice |
| y | the y position of the slice |
| type | 1->top field, 2->bottom field, 3->frame |
| offset | offset into the AVFrame.data from which the slice should be read |

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 AV_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.
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.
Some decoders do not support linesizes changing between frames.
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.

| attribute_deprecated int AVCodecContext::refcounted_frames |
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.
This is always automatically enabled if avcodec_receive_frame() is used.

| int AVCodecContext::skip_alpha |
Skip processing alpha if supported by codec.
Note that if the format uses pre-multiplied alpha (common with VP6, and recommended due to better video quality/compression) the image will look as if alpha-blended onto a black background. However for formats that do not use pre-multiplied alpha there might be serious artefacts (though e.g. libswscale currently assumes pre-multiplied alpha anyway).

| AVBufferRef* AVCodecContext::hw_frames_ctx |
A reference to the AVHWFramesContext describing the input (for encoding) or output (decoding) frames.
The reference is set by the caller and afterwards owned (and freed) by libavcodec - it should never be read by the caller after being set.
decoding: This field should be set by the caller from the get_format() 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.
This field should be set before avcodec_open2() is called.

| AVBufferRef* AVCodecContext::hw_device_ctx |
A reference to the AVHWDeviceContext describing the device which will be used by a hardware encoder/decoder.
The reference is set by the 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.

| int AVCodecContext::apply_cropping |
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.
