struct GstAudioClock

struct GstAudioClock;

Opaque GstAudioClock.

GstAudioClockGetTimeFunc ()

GstClockTime        (*GstAudioClockGetTimeFunc)         (GstClock *clock,
                                                         gpointer user_data);

This function will be called whenever the current clock time needs to be calculated. If this function returns GST_CLOCK_TIME_NONE, the last reported time will be returned by the clock.

gst_audio_clock_new ()

GstClock *          gst_audio_clock_new                 (const gchar *name,
                                                         GstAudioClockGetTimeFunc func,
                                                         gpointer user_data);

Create a new GstAudioClock instance. Whenever the clock time should be calculated it will call func with user_data. When func returns GST_CLOCK_TIME_NONE, the clock will return the last reported time.

gst_audio_clock_new_full ()

GstClock *          gst_audio_clock_new_full            (const gchar *name,
                                                         GstAudioClockGetTimeFunc func,
                                                         gpointer user_data,
                                                         GDestroyNotify destroy_notify);

Create a new GstAudioClock instance. Whenever the clock time should be calculated it will call func with user_data. When func returns GST_CLOCK_TIME_NONE, the clock will return the last reported time.

gst_audio_clock_adjust ()

GstClockTime        gst_audio_clock_adjust              (GstClock *clock,
                                                         GstClockTime time);

Adjust time with the internal offset of the audio clock.

gst_audio_clock_get_time ()

GstClockTime        gst_audio_clock_get_time            (GstClock *clock);

Report the time as returned by the GstAudioClockGetTimeFunc without applying any offsets.

Since 0.10.23

gst_audio_clock_reset ()

void                gst_audio_clock_reset               (GstAudioClock *clock,
                                                         GstClockTime time);

Inform clock that future calls to GstAudioClockGetTimeFunc will return values starting from time. The clock will update an internal offset to make sure that future calls to internal_time will return an increasing result as required by the GstClock object.

gst_audio_clock_invalidate ()

void                gst_audio_clock_invalidate          (GstClock *clock);

Invalidate the clock function. Call this function when the provided GstAudioClockGetTimeFunc cannot be called anymore, for example, when the user_data becomes invalid.

After calling this function, clock will return the last returned time for the rest of its lifetime.
