#define GST_FRAMES_TO_CLOCK_TIME(frames, rate)
Calculate clocktime from sample frames and rate.
| frames: | sample frames | 
| rate: | sampling rate | 
#define GST_CLOCK_TIME_TO_FRAMES(clocktime, rate)
Calculate frames from clocktime and sample rate.
| clocktime: | clock time | 
| rate: | sampling rate | 
int gst_audio_frame_byte_size (GstPad *pad);
Calculate byte size of an audio frame.
| pad: | the GstPad to get the caps from | 
| Returns : | the byte size, or 0 if there was an error | 
long gst_audio_frame_length (GstPad *pad, GstBuffer *buf);
Calculate length of buffer in frames.
GstClockTime gst_audio_duration_from_pad_buffer (GstPad *pad, GstBuffer *buf);
Calculate length in nanoseconds of audio buffer buf based on capabilities of
pad.
Return: the length.
gboolean gst_audio_is_buffer_framed (GstPad *pad, GstBuffer *buf);
Check if the buffer size is a whole multiple of the frame size.
void gst_audio_structure_set_int (GstStructure *structure, GstAudioFieldFlag flag);
Do not use anymore.
Deprecated: use gst_structure_set()
| structure: | a GstStructure | 
| flag: | a set of GstAudioFieldFlag |
