◆ ff_framequeue_take()

AVFrame* ff_framequeue_take ( FFFrameQueue * fq )

Take the first frame in the queue.

Must not be used with empty queues.

◆ ff_framequeue_peek()

AVFrame* ff_framequeue_peek	(	FFFrameQueue *	fq,
		size_t	idx
	)

Access a frame in the queue, without removing it.

The first frame is numbered 0; the designated frame must exist.

◆ ff_framequeue_skip_samples()

void ff_framequeue_skip_samples	(	FFFrameQueue *	fq,
		size_t	samples,
		AVRational	time_base
	)

Skip samples from the first frame in the queue.

This function must be used when the first frame was accessed using ff_framequeue_peek() and samples were consumed from it. It adapts the data pointers and timestamps of the head frame to account for the skipped samples.
