void ff_af_queue_close

(

AudioFrameQueue *

afq

)

Close AudioFrameQueue.

Frees memory if needed.

Parameters

afq	queue context

int ff_af_queue_add	(	AudioFrameQueue *	afq,
		const AVFrame *	f
	)

Add a frame to the queue.

Parameters

afq	queue context
f	frame to add to the queue

void ff_af_queue_remove	(	AudioFrameQueue *	afq,
		int	nb_samples,
		int64_t *	pts,
		int64_t *	duration
	)

Remove frame(s) from the queue.

Retrieves the pts of the next available frame, or a generated pts based on the last frame duration if there are no frames left in the queue. The number of requested samples should be the full number of samples represented by the packet that will be output by the encoder. If fewer samples are available in the queue, a smaller value will be used for the output duration.

Parameters

	afq	queue context
	nb_samples	number of samples to remove from the queue
[out]	pts	output packet pts
[out]	duration	output packet duration
