struct AVCodecContext

Defined at line 435 of file ../../prebuilt/third_party/ffmpeg/pkg/ffmpeg/include/libavcodec/avcodec.h

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*.
