oggdemux: Should send NEWSEGMENT events and active chains from streaming thread when seeking
Submitted by Sebastian Dröge
In pull mode seeking, oggdemux currently sends the close-newsegment event (in the non-flush case) and the new newsegment events from the seek thread. Also the new chain, if any, is activated from the seek thread.
This could block the application very much, especially if the newsegment event is going to trigger a pad block somewhere.
