Members

connectValueAdded ulong connectValueAdded(T callback, Flag!"After" after): Connect to ValueAdded signal.
connectValueChanged ulong connectValueChanged(T callback, Flag!"After" after): Connect to ValueChanged signal.
connectValueRemoved ulong connectValueRemoved(T callback, Flag!"After" after): Connect to ValueRemoved signal.
findControlPointIter glib.sequence_iter.SequenceIter findControlPointIter(gst.types.ClockTime timestamp): Find last value before given timestamp in control point list. If all values in the control point list come after the given timestamp or no values exist, null is returned.
getAll gst.types.TimedValue[] getAll(): Returns a read-only copy of the list of #GstTimedValue for the given property. Free the list after done with it.
getCount int getCount(): Get the number of control points that are set.
set bool set(gst.types.ClockTime timestamp, double value): Set the value of given controller-handled property at a certain time.
setFromList bool setFromList(gst.types.TimedValue[] timedvalues): Sets multiple timed values at once.
unset bool unset(gst.types.ClockTime timestamp): Used to remove the value of given controller-handled property at a certain time.
unsetAll void unsetAll(): Used to remove all time-stamped values of given controller-handled property

controlSourceGetValue bool controlSourceGetValue(gst.types.ClockTime timestamp, double value): Gets the value for this #GstControlSource at a given timestamp.
controlSourceGetValueArray bool controlSourceGetValueArray(gst.types.ClockTime timestamp, gst.types.ClockTime interval, double[] values): Gets an array of values for for this #GstControlSource. Values that are undefined contain NANs.
