Comment 1 Ronald Bultje 2005-02-16 09:40:16 UTC

William, can you provide a small bit of this .vob file so I can reproduce it? If
it's reproduceable with any vob file, let me know and I'll think of a better
test to narrow it down.

Comment 2 William Jon McCann 2005-02-16 20:05:55 UTC

Created attachment 37564 [details]
foo.vob

head -5000 /media/cdrecorder/VIDEO_TS/VTS_01_0.VOB > foo.vob

Comment 3 Jan Schmidt 2005-02-17 02:16:18 UTC

Hrmn, that's only about 8k - approximately 1 frame (and doesn't crash here). A
few MB would be better - if you have a spot you could upload to, please place it
there and give us the URL.

Comment 4 William Jon McCann 2005-02-17 03:33:24 UTC

Actually, I had assumed that the vob file was large so I did the head without
even looking at the original file size.  Now that I have, I realize that the
entire file is only 8k.

I doesn't crash every time for me.  It crashes more often if the system is
heavily loaded.  Try running a "find / -print" or something at the same time.

Also you have to push play in totem for it to crash.

Comment 5 Stephane Loeuillet 2005-02-20 13:10:51 UTC

ok, so this is a still image at start of DVD

it is supposed to be skipped actually, no ?

Comment 6 Jan Schmidt 2005-02-20 14:32:01 UTC

I think the problem is possibly to do with state changes, and the file ending
too quickly

Comment 7 Ronald Bultje 2005-02-25 09:13:02 UTC

That makes it a dup of the tracker for this, #165929.
