Function Documentation

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_close ( AudioFrameQueue afq  ) 

Close AudioFrameQueue.

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_log_state ( AudioFrameQueue afq  ) 

Log the current state of the queue.

Parameters:
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
