This is the base class for audio sources. Subclasses need to implement the ::create_ringbuffer vmethod. This base class will then take care of reading samples from the ringbuffer, synchronisation and flushing.

typedef struct {
  GstPushSrcClass parent_class;
  /* subclass ringbuffer allocation */
  GstRingBuffer* (*create_ringbuffer)  (GstBaseAudioSrc *src);
} GstBaseAudioSrcClass;
GstBaseAudioSrc class. Override the vmethod to implement functionality.
| GstPushSrcClass parent_class; | the parent class. | 
| create_ringbuffer() | create and return a GstRingBuffer to read from. | 
#define GST_BASE_AUDIO_SRC_CLOCK(obj) (GST_BASE_AUDIO_SRC (obj)->clock)
Get the GstClock of obj.
| obj: | a GstBaseAudioSrc | 
#define GST_BASE_AUDIO_SRC_PAD(obj) (GST_BASE_SRC (obj)->srcpad)
Get the source GstPad of obj.
| obj: | a GstBaseAudioSrc | 
GstRingBuffer* gst_base_audio_src_create_ringbuffer (GstBaseAudioSrc *src);
Create and return the GstRingBuffer for src. This function will call the
::create_ringbuffer vmethod and will set src as the parent of the returned
buffer (see gst_object_set_parent()).
| src: | a GstBaseAudioSrc. | 
| Returns : | The new ringbuffer of src. |
