public void disable_sync_message_emission ()
Instructs GStreamer to stop emitting the "sync-message" signal for this bus.
See enable_sync_message_emission for more information.
In the event that multiple pieces of code have called enable_sync_message_emission, the sync-message emissions will only be stopped after all calls to enable_sync_message_emission were "cancelled" by calling this function. In this way the semantics are exactly the same as @ref that which calls enable should also call disable.
