Field Documentation

◆ is_copy

int AVCodecInternal::is_copy

When using frame-threaded decoding, this field is set for the first worker thread (e.g.

to decode extradata just once).

◆ is_frame_mt

int AVCodecInternal::is_frame_mt

This field is set to 1 when frame threading is being used and the parent AVCodecContext of this AVCodecInternal is a worker-thread context (i.e.

one of those actually doing the decoding), 0 otherwise.
