◆ ff_af_queue_remove()

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.
