[MPlayer-users] MPlayer crashes playing DVDs via dvdnav:// since the recent libdvdnav updates

[Ilja Sekler]

Hello,

since r1245 of libdvdnav

########################################################################

r1245 | rathann | 2012-12-09 22:13:14 +0100 (Sun, 09 Dec 2012) | 4 lines
Changed paths:
   M /trunk/libdvdnav/src/vm/vm.c

Fix failed assertion when there's no menu.

Patch by Erik Hovland.

########################################################################

MPlayer crashes immediately when trying to play a DVD (every DVD I tried
so far) via dvdnav:// with either


mplayer: libdvdnav/vm/vm.c:417: vm_new_copy: Assertion `pgcN' failed.


or


mplayer: libdvdnav/vm/vm.c:1586: process_command: Assertion `0' failed.


followed by


MPlayer interrupted by signal 6 in module: open_stream


as its last words. Reverting libdvdnav to the state prior to r1245 fixes
the breakage. gdb output attached.

MPlayer r35712 on Fedora 17 with kernel 3.6.11-1.fc17.x86_64.

Thanks,

Regards
