Constructor Details

#initialize(name, func, user_data, destroy_notify) ⇒ Gst::Clock

Create a new Gst::AudioClock 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.

Parameters:

  • name (String) —

    the name of the clock

  • func (GstAudio::AudioClockGetTimeFunc) —

    a function

  • user_data (GObject) —

    user data

  • destroy_notify (GLib::DestroyNotify) —

    GDestroy::Notify for user_data

Instance Method Details

#adjust(time) ⇒ Gst::ClockTime

Adjust time with the internal offset of the audio clock.

Parameters:

  • time (Gst::ClockTime) —

    a Gst::ClockTime

Returns:

  • (Gst::ClockTime) —

    time adjusted with the internal offset.

#invalidate ⇒ nil

Invalidate the clock function. Call this function when the provided Gst::AudioClockGetTimeFunc 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.

Returns:

  • (nil)

#reset(time) ⇒ nil

Inform clock that future calls to Gst::AudioClockGetTimeFunc 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 Gst::Clock object.

Parameters:

  • time (Gst::ClockTime) —

    a Gst::ClockTime

Returns:

  • (nil)

#time ⇒ Gst::ClockTime

Report the time as returned by the Gst::AudioClockGetTimeFunc without applying any offsets.

Returns:

  • (Gst::ClockTime) —

    the time as reported by the time function of the audio clock
