Description Jono Bacon 2006-08-22 13:53:32 UTC
The attached sample program uses a gnloperation. Inside the operation is a bin with the following:  audioconver ! ladspa-delay-5s ! audioconvert. Although I use a ladspa-delay-5s here, feel free to replace it with a 'volume' element and the same problem occurs. You can change this on line 39 of the sample program.

I have made sure to set the priorities correctly of the gnlfilesource and gnloperation, and made sure the bin inside the operation has ghost pads, but I get the following problem when I change the state to PLAYING:

	* gnl/gnlcomposition.c: (gnl_composition_init),
	(gnl_composition_reset), (gnl_composition_event_handler),
	(no_more_pads_object_cb), (compare_relink_single_node),
	(compare_relink_stack), (update_pipeline):
	Only set ghostpad target and/or send seek event once all the objects of
	the stack are linked.
	Fixes #352389
	This is done through the use of comp->private->waitingpads.
	Simplified update_pipeline accordingly.
	Added more comments.
