[MPlayer-users] mencoder crashes kernel

[Duane Evenson]

My kernel crashes whenever I run mencoder. It may not crash right away,
not even while mencoder is still running, but it crashes soon.
My mencoder command is:
mencoder -tv
driver=v4l2:buffersize=300:alsa:width=640:height=480:norm=NTSC:chanlist=us-cable:channel=8:audiorate=48000 

tv:// -ovc lavc -lavcopts vcodec=mpeg4:v4mv -vf crop=608:464:16:6,pp=lb
-oac mp3lame -lameopts q=2 -quiet -endpos 60 -o test.avi;

The problem started after I upgraded from 2.4.20 to 2.6.x (I've tried
x=11, 12, 13, and 14). The problem presents using Fedora 4 precompiled
kernels as well as my own compiled kernels. I'm currently using MEncoder
dev-Fedora-GS-CVS-050904-14:36-4.0.1, and bttv0: Bt878 (rev 17). I have
a mostly Redhat Fedora 4 system.

Someone mentioned that this may be a problem between level 1 and level 2
in v4l. I don't know. It always seems that from the call trace section
of the log, the problem arises during memory page swapping.

Here's the log file from the time the system crashed. Note the time,
mencoder was running for about 7 minutes.

I hope someone can help me. I used to use my computer all the time as a
VCR. I'd like to do so again.
