I have used gdb to debug and find out it is due to deadlock between two threads. and the further cause is:when our video sink thread call XOpenDisplay() which will lock _Xglobal_lock to do something and does not completed, totem thread call some func and lock _Xglobal_lock too, which cause our video sink thread poll something and can not unlock _Xglobal_lock. I think gdk is not thread safe, so I call gdk_threads_init to use GDK_THREADS_ENTER and GDK_THREADS_LEAVE before and after calling XOpenDisplay(), and it is ok ! however, it cause another bug: when I switch media file in the playlist manually to play, totem is blocked too. I continue using gdb to find out the reason: some func call another func, they are in the same thread, both of them are call GDK_THREADS_ENTER. it will cause deadlock if lock twice in the same thread. the two funcs are gdk_event_source_dispatch and gdk_event_source_prepare. So I doubt that, why totem does not use GDK_THREADS_ENTER and GDK_THREADS_LEAVE default (does not call gdk_threads_init yet). if use, it will cause the problem I met. my system: ubuntu: 11.10 totem: 3.0.1 gtk+: 3.4.4 best regards !
