This structure describes decoded (raw) audio or video data.
#define AV_LOG_WARNING
Something somehow does not look correct.
void av_log(void *avcl, int level, const char *fmt,...) av_printf_format(3
Send the specified message to the log if the level is less than or equal to the current av_log_level...
AVRational time_base
This is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented...
void av_freep(void *ptr)
Free a memory block which has been allocated with av_malloc(z)() or av_realloc() and set the pointer ...
av_cold void ff_af_queue_init(AVCodecContext *avctx, AudioFrameQueue *afq)
Initialize AudioFrameQueue.
int64_t pts
Presentation timestamp in time_base units (time when frame should be shown to user).
int64_t av_rescale_q(int64_t a, AVRational bq, AVRational cq) av_const
Rescale a 64-bit integer by 2 rational numbers.
#define AV_LOG_DEBUG
Stuff which is only useful for libav* developers.
int ff_af_queue_add(AudioFrameQueue *afq, const AVFrame *f)
Add a frame to the queue.
void * av_fast_realloc(void *ptr, unsigned int *size, size_t min_size)
Reallocate the given block if it is not large enough, otherwise do nothing.
int sample_rate
samples per second
main external API structure.
rational number numerator/denominator
common internal api header.
void ff_af_queue_remove(AudioFrameQueue *afq, int nb_samples, int64_t *pts, int *duration)
Remove frame(s) from the queue.
void ff_af_queue_close(AudioFrameQueue *afq)
Close AudioFrameQueue.
#define av_assert0(cond)
assert() equivalent, that is always enabled.
static av_always_inline int64_t ff_samples_to_time_base(AVCodecContext *avctx, int64_t samples)
Rescale from sample rate to AVCodecContext.time_base.
int nb_samples
number of audio samples (per channel) described by this frame
#define AV_NOPTS_VALUE
Undefined timestamp value.
