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. - encoding: Set by user, if not then the default based on codec_id will be used. - decoding: Set by user, will be converted to uppercase by libavcodec during init.

  - time_base
```
@ByRef
public AVRational 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) - encoding: MUST be set by user. - decoding: unused.
  - time_base
```
public AVCodecContext time_base(AVRational setter)
```
  - ticks_per_frame
```
public int 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.
  - ticks_per_frame
```
public AVCodecContext ticks_per_frame(int setter)
```
  - delay
```
public int 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. - encoding: Set by libavcodec. - decoding: Set by libavcodec.

  - width
```

Some decoders will require the dimensions to be set by the caller. During decoding, the decoder may overwrite those values as required while parsing the data.

  - hw_frames_ctx
```
public AVBufferRef 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.
  - hw_frames_ctx

  - max_pixels
```
public AVCodecContext max_pixels(long setter)
```
  - hw_device_ctx
```
public AVBufferRef 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.
  - hw_device_ctx

public AVCodecContext hw_device_ctx(AVBufferRef setter)

public int hwaccel_flags()

  - hwaccel_flags
```
public AVCodecContext hwaccel_flags(int setter)
```
  - apply_cropping
```
public int 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. \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).
