Hello,

Mencoder is segfaulting most of the times I try to use snow. The odd part is that it's not 100% reproducible. Actually, it's 0% reproducible. Every time I run mencoder the output is different; most of the time it segfaults on the first few frames, and about 5% of the time it gets to around the 85th frame before segfaulting anyway.

I built an i386 mencoder and ran it under my i386 chroot, and that used snow without any problems, so I'm pretty sure the problem isn't my machine being a whole lot more flaky than I thought. :)

The command I'm using is:
mencoder snow-segfault.vob -nosound -ofps 24000/1001 -ovc lavc \
-lavcopts vcodec=snow:vstrict=-1

The source file doesn't seem to matter (it even happens with /dev/urandom). I've uploaded a 1MB clip to:
ftp://ftp.mplayerhq.hu/MPlayer/incoming/snow-amd64/
--and--
http://fatooh.org/files/mpbug/snow-amd64/

There's also a sample 'mencoder -v' log, a gdb log, and the text of this email (the two logs are attached, too).

======================================================================
Here's the system I'm using:

MEncoder dev-CVS-050416-15:14-3.4.4 (C) 2000-2005 MPlayer Team

Debian-amd64 "Pure64 Sid"

Linux bugfood 2.6.11.6 #1 Fri Apr 1 12:04:37 PST 2005 x86_64 GNU/Linux

gcc version 3.4.4 20050314 (prerelease) (Debian 3.4.3-12)

GNU ld version 2.15

=======================================================================

Please tell me if there's anything more I can do; I'd be happy to assist.

Thank you,
Corey
