Description Andy Wingo 2006-02-10 15:50:47 UTC
Apps that want to deal with sync-message currently have to call gst_bus_set_sync_handler (gst_bus_sync_signal_handler, NULL). Aside from being difficult for language bindings, this affects the sync handler, which some other part of the application might have set.

To allow emission of sync-message, I propose two new functions, gst_bus_enable_sync_message_emission, and gst_bus_disable_sync_message_emission. Patch attached.

	(gst_bus_post): Emit the sync-message signal if the user asked for
	it. Fixes #330684.

	location of the bus-private structuure.
	(gst_bus_disable_sync_message_emission): New public functions.
