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

typedef struct { GstBaseSinkClass parent_class; /* subclass ringbuffer allocation */ GstRingBuffer* (*create_ringbuffer) (GstBaseAudioSink *sink); } GstBaseAudioSinkClass;
GstBaseAudioSink class. Override the vmethod to implement functionality.
GstBaseSinkClass parent_class; | the parent class. |
create_ringbuffer () | create and return a GstRingBuffer to write to. |
typedef enum { GST_BASE_AUDIO_SINK_SLAVE_RESAMPLE, GST_BASE_AUDIO_SINK_SLAVE_SKEW, } GstBaseAudioSinkSlaveMethod;
Different possible clock slaving algorithms
#define GST_BASE_AUDIO_SINK_CLOCK(obj) (GST_BASE_AUDIO_SINK (obj)->clock)
Get the GstClock of obj.
obj : | a GstBaseAudioSink |
#define GST_BASE_AUDIO_SINK_PAD(obj) (GST_BASE_SINK (obj)->sinkpad)
Get the sink GstPad of obj.
obj : | a GstBaseAudioSink |
GstRingBuffer* gst_base_audio_sink_create_ringbuffer (GstBaseAudioSink *sink);
Create and return the GstRingBuffer for sink. This function will call the ::create_ringbuffer vmethod and will set sink as the parent of the returned buffer (see gst_object_set_parent()).
sink : | a GstBaseAudioSink. |
Returns : | The new ringbuffer of sink. |
"buffer-time" gint64 : Read / Write
Size of audio buffer in microseconds.
Allowed values: >= 1
Default value: 200000
"latency-time" gint64 : Read / Write
Audio latency in microseconds.
Allowed values: >= 1
Default value: 10000
"provide-clock" gboolean : Read / Write
Provide a clock to be used as the global pipeline clock.
Default value: TRUE
"slave-method" GstBaseAudioSinkSlaveMethod : Read / Write
Algorithm to use to match the rate of the masterclock.
Default value: Skew slaving
