Field Documentation

◆ post_process

int(* FrameDecodeData::post_process) (void *logctx, AVFrame *frame)

The callback to perform some delayed processing on the frame right before it is returned to the caller.

Note: This code is called at some unspecified point after the frame is returned from the decoder's decode/receive_frame call. Therefore it cannot rely on AVCodecContext being in any specific state, so it does not get to access AVCodecContext directly at all. All the state it needs must be stored in the post_process_opaque object.
