motion crashes with "trap invalid opcode" from kernel

Question

Hi,

I'm setting up motion 3.2.7 on a Fedora Core 6 installation. Actual kernel is 2.6.19 (x86_64), not the FC6 default. Ffmpeg is is SVN-r6835. Motion was compiled from source, only with ffmpeg, no mysql or postgres

The 1st times I noticed this crash were allways very close to midnight, so I think that it may be related to the timelapse video (

ffmpeg_timelapse_mode daily, timelapse_filename cam%t.%Y%m%d.lap

)

After I found out that motions dies I set up a watcher using cron checking if the process exists every 2 minutes, if it's not there it's is launched again. The funny thing is that most of the times it takes 4 or 5 tries to get motion running ok.

Take a look at this log. Motion is started at 14:45:34, dies at 14:46:30. The watcher notices this and reloads motion at 14:48:01, it crashes again at 14:49:00. The watcher reloads it at 14:50:01, and it dies again at 14:51:00. It's reloaded again at 14:52:01 and it has been running since than (now it's 15:52). I expect it do die again at about 00:00:30 and go for another crash/reload fandango.

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

I'm at a loss here, motion problem or kernel problem ? I compiled this kernel myself, maybe I should try it with the default fc6. This is a 64 bits kernel but I could try with a 32 bits.

I think that this version of ffmpeg is not 100% ok, as it was impossible to use the msmpeg4 codec. Motion was dumping core during the creation of the 1st movie. As this is not a problem for me I didn't tryed to fix it but maybe it's the source of the problem.

Any clues, anyone ???

i have tested latest version of ffmpeg and working fine in a 32bits environment :

Also i have tried with a kernel version 2.6.19-1 without problems ... so maybe the problems is the 64bits environment ...

Btw seems that you didn't compile ffmpeg with shared libraries ( --enable-shared ) try to build ffmpeg on this way first.

I didn't compile ffmpeg at all, just installed a RPM, then compiled motion.

root@conan:~ # uname -a
Linux conan 2.6.19.vasco.1 #2 SMP Wed Dec 6 18:16:27 WET 2006 x86_64 x86_64 x86_64 GNU/Linux

root@conan:~ # rpm -qa | grep -i ffmpeg
ffmpeg-devel-0.4.9-0.25.20061030.lvn6
gstreamer-ffmpeg-debuginfo-0.10.1-1.fc6.rf
ffmpeg-0.4.9-0.25.20061030.lvn6
gstreamer-ffmpeg-0.10.1-1.fc6.rf

By the way, no crashes at all this night... All went well.

I guess I'll have to build ffmpeg after all. I don't like very much the fact that ffmpeg don't have formal releases, normally I don't use betas or overnight builds on production servers (and this is a production machine). Is there a recommended ffmpeg version for this version of motion ?

thanks.
