ff_thread_receive_frame()

int ff_thread_receive_frame	(	struct AVCodecContext *	avctx,
		AVFrame *	frame
	)

Submit available packets for decoding to worker threads, return a decoded frame if available.

Returns AVERROR(EAGAIN) if none is available.

Parameters are the same as FFCodec.receive_frame.

Definition at line 566 of file pthread_frame.c.

ff_decode_receive_frame_internal()

int ff_decode_receive_frame_internal	(	struct AVCodecContext *	avctx,
		AVFrame *	frame

Do the actual decoding and obtain a decoded frame from the decoder, if available.

When frame threading is used, this is invoked by the worker threads, otherwise by the top layer directly.
