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. |
