I have a little problem when replaying recordings. Sometimes (seldom) vdr crashes during replay. When i check the backtrace its always the same, the mi pointer cMarks::Get is wrong.
The backtrace:
#0 Get__6cMarksi (this=0x8621f10, Position=8780) at recording.c:1429 1429 if (mi->position == Position) (gdb) bt #0 Get__6cMarksi (this=0x8621f10, Position=8780) at recording.c:1429 #1 0x080a3546 in Action__10cDvbPlayer (this=0x87a77b8) at dvbplayer.c:692 #2 0x080ff884 in StartThread__7cThreadP7cThread (Thread=0x87a77c4) at thread.c:244 #3 0xb7ee30ba in pthread_start_thread () from /lib/libpthread.so.0
If I read the backtrace correctly, then cMarks::Get() is called from cDvbPlayer::Action(). Since plain vanilla VDR doesn't call cMarks::Get() from cDvbPlayer::Action(), this crash is most probably caused by a patch. Cheers, Udo
thanks for the hint, now i've looked in the sources, it seems to be triggered by the cMarks::Get() call of the JumpPlay Patch. But why the mi pointer can go corrupt when Get itterate through the marks? May be a problem with parallel access from different threads?
