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.

#define GST_BASE_AUDIO_SRC_CLOCK(obj) (GST_BASE_AUDIO_SRC (obj)->clock)
Get the GstClock of obj
.
#define GST_BASE_AUDIO_SRC_PAD(obj) (GST_BASE_SRC (obj)->srcpad)
Get the source GstPad of obj
.
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()
).
void gst_base_audio_src_set_provide_clock (GstBaseAudioSrc *src
,gboolean provide
);
Controls whether src
will provide a clock or not. If provide
is TRUE
,
gst_element_provide_clock()
will return a clock that reflects the datarate
of src
. If provide
is FALSE
, gst_element_provide_clock()
will return NULL.
Since 0.10.16
gboolean
gst_base_audio_src_get_provide_clock (GstBaseAudioSrc *src
);
Queries whether src
will provide a clock or not. See also
gst_base_audio_src_set_provide_clock.
Since 0.10.16
GstBaseAudioSrcSlaveMethod
gst_base_audio_src_get_slave_method (GstBaseAudioSrc *src
);
Get the current slave method used by src
.
Since 0.10.20
void gst_base_audio_src_set_slave_method (GstBaseAudioSrc *src
,GstBaseAudioSrcSlaveMethod method
);
Controls how clock slaving will be performed in src
.
Since 0.10.20
struct GstBaseAudioSrcClass { GstPushSrcClass parent_class; /* subclass ringbuffer allocation */ GstRingBuffer* (*create_ringbuffer) (GstBaseAudioSrc *src); };
GstBaseAudioSrc class. Override the vmethod to implement functionality.
