GstClock Clocking and synchronisation. GstClock provides an easy way to synchonize against a global clock. Calculate the difference between to timestamps. This does not create and absolute difference so the result might be negative if the first timestamp is less than the second timestamp. @s: first timestamp @e: second timestamp @name: @start_time: @current_time: @adjust: @locking: @sinkobjects: @num: @num_locked: @sinkmutex: @lock: @name: @Returns: @Returns: @clock: @obj: @clock: @time: @clock: @clock: @time: @obj: @clock: @time: @Returns:
