According to the assertion message this is a bug in libdvdnav instead of vlc.

[Sam Liddicott (sam-liddicott)]

I think this is a duplicate of 370884

I also have the bug, back-traces attached.

The bug affects me with totem, vlc and xine

xine doesn't crash, but reports (as does totem):
libdvdread: Found 3 VTS's
libdvdread: Elapsed time 0
libdvdread: Can't seek to block 1011614
libdvdread: Invalid IFO for title 2 (VTS_02_0.IFO).

Sometimes totem "works" (usually for me) but often fails as reported (usually for my wife). Today it fails for me!

Sometimes VLC works (without DVD menus) but then when skipping to later chapters reports:
[0x9658a18] libmpeg2 decoder error: DpbUnlinkPicture called on an invalid picture
libdvdread: Can't seek to block 614496
[0x947b698] dvdread demux error: read failed for block 600501
QPainter::begin: Paint device returned engine == 0, type: 1

but yet "dmesg" doesn't report any failures to read

[BTW when I try to report a bug from within totem, the console reports:
Error: Failed to send command: 500 command not parseable]

I can and do confirm that on Linux 8thdaydev-LINUX 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux vlc does not crash but works quite well. A recent release fixed that and totem.

[bwallum (rbw2)]

Went to open an iso file and vlc crashed. Same with Movie Player

[Alex (alexander-stehlik)]

I can confirm this bug for 9.10. I get it in vlc and totem after running the install-css.sh Script in the /usr/share/doc/libdvdread4 folder.

[Karl Bielefeldt (kbielefe)]

I can also confirm this bug for 9.10, trying to open a commercial DVD from VLC. It went away when I installed libdvdcss2.

[imachine (m-jedrasik)]

I am having the same bug with Totem, trying to play a DVD in the latest Lucid Lynx on amd64.\

It seems it's a libdvdnav issue, not a vlc nor Totem issue.

[quequotion (quequotion)]

I'm getting this with one particular DVD only.

totem: /build/buildd/libdvdnav-4.1.3/src/vm/vm.c:1485: process_command: Assertion `0' failed.

The DVD is region 2, but by drive is region free...

What's going on?

[quequotion (quequotion)]

A little further information, I'm having this problem in Lucid Lynx with libdvdcss2 installed.
Other DVDs from various regions play without issue.
Just one in particular seems not to play.

Perhaps it uses an encoding that is somehow different from the usual?
The copyright warning and company logos appear just before whatever player used crashes.

[Jan Heitkötter (jan-heitkoetter)]

Bug still present in 12.04 with Totem. Trying to play a DVD image created with dvd95.

[Bryce Harrington (bryce)]

Here is the assert being hit:

 if (!ifoOpenNewVTSI(vm, vm->dvd, link_values.data1)) /* Also sets (vm->state).vtsN */
    assert(0);

Note that vm.c is littered with assert(0)'s, so there are many paths to failure that will generate this same "Assertion `0' failed" error, but these won't all be the same bug.

Can you share a DVD title that still has this issue?
