/**
* Audio Video Frame.
* New fields can be added to the end of AVFRAME with minor version
* bumps. Removal, reordering and changes to existing fields require
* bumps. 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.
* Removal, reordering and changes in the remaining cases require
* a major version bump.
* sizeof(AVFrame) must not be used outside libav*.
