struct GstBaseAudioSrc

struct GstBaseAudioSrc;

Opaque GstBaseAudioSrc.

struct GstBaseAudioSrcClass

struct GstBaseAudioSrcClass {
  GstPushSrcClass parent_class;

  /* subclass ringbuffer allocation */
  GstRingBuffer* (*create_ringbuffer)  (GstBaseAudioSrc *src);
};

GstBaseAudioSrc class. Override the vmethod to implement functionality.

enum GstBaseAudioSrcSlaveMethod

typedef enum {
  GST_BASE_AUDIO_SRC_SLAVE_RESAMPLE,
  GST_BASE_AUDIO_SRC_SLAVE_RETIMESTAMP,
  GST_BASE_AUDIO_SRC_SLAVE_SKEW,
  GST_BASE_AUDIO_SRC_SLAVE_NONE
} GstBaseAudioSrcSlaveMethod;

Different possible clock slaving algorithms when the internal audio clock was not selected as the pipeline clock.

GST_BASE_AUDIO_SRC_CLOCK()

#define GST_BASE_AUDIO_SRC_CLOCK(obj)    (GST_BASE_AUDIO_SRC (obj)->clock)

Get the GstClock of obj.

GST_BASE_AUDIO_SRC_PAD()

#define GST_BASE_AUDIO_SRC_PAD(obj)      (GST_BASE_SRC (obj)->srcpad)

Get the source GstPad of obj.

gst_base_audio_src_create_ringbuffer ()

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()).

gst_base_audio_src_set_provide_clock ()

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.

gst_base_audio_src_get_provide_clock ()

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.

gst_base_audio_src_get_slave_method ()

GstBaseAudioSrcSlaveMethod gst_base_audio_src_get_slave_method
                                                        (GstBaseAudioSrc *src);

Get the current slave method used by src.

Controls how clock slaving will be performed in src.
