pipeline deadlock when switch from ffx2 to ffx4
When we tried to test the trick mode for one mpeg4/mp3 stream, sometimes it will hang while switch from ffx2 to ffx4
- We did some checking and found when the pipeline hang (switch from ffx2 to ffx4), demux tried to push FLUSH_STOP event before seeking, and never come back.
- And below is the backtrace of when it hang: backtrace.txt
- looks like the playsink sink event is deadlocked (thread 2 ), and meanwhile one track is waiting preroll (thread 12) and can't let FLUSH_STOP event done.
Did anyone meet this kind of situation ? (Not always this can reproduce, we use a loop playback and switch rate, it need a while to reproduce hang)
Any suggestion would be appreciated, thanks a lot ~
Lyon
