Removing the pthread_setschedparam() helps to prevent a complete lockup in my setup. Unfortunately the soft lockups which require the "kill -9" still occur. The patch attached seems to help, but hasn't had much testing.
As in mine, removing pthread_setschedparam() helps a little but not completly.
The patch attached also seems to help the plugin recover more gracefully when it gets some bad data. It still needs some more work because sometimes the stream still needs to be manually stopped and restarted to resume playback (but at least it does stop instead, rather than locking up vdr).
This sounds better than manual vdr restart.
I think the problem that this patch helps address is that the dvbplayer thread gets stuck waiting for the flush to finish and the main VDR thread cancels it. Unfortunately the thread sometimes holds a lock on the dxr3syncbuffer and this stops the video output thread. With the patch applied, the flush returns and thread exits before the 3 second thread cancel timeout.
Now I'm tesing your patch, after while I return some feedback :-)
