void ff_af_queue_close

(

AudioFrameQueue *

afq

)

Frees memory if needed.

Parameters

afq	queue context

void ff_af_queue_init	(	AVCodecContext *	avctx,
		AudioFrameQueue *	afq
	)

Initialize AudioFrameQueue.

Parameters

avctx	context to use for time_base and av_log
afq	queue context

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