Field Documentation

◆ is_copy

int AVCodecInternal::is_copy

Whether the parent AVCodecContext is a copy of the context which had init() called on it.

This is used by multithreading - shared tables and picture pointers should be freed from the original context only.

◆ last_audio_frame

An audio frame with less than required samples has been submitted and padded with silence.

Reject all subsequent frames.
