Field Documentation

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.

int AVCodecInternal::allocate_progress

Whether to allocate progress for frame threading.

The codec must set it to 1 if it uses ff_thread_await/report_progress(), then progress will be allocated in ff_thread_get_buffer(). The frames then MUST be freed with ff_thread_release_buffer().

If the codec does not need to call the progress functions (there are no dependencies between the frames), it should leave this at 0. Then it can decode straight to the user-provided frames (which the user will then free with av_frame_unref()), there is no need to call ff_thread_release_buffer().
