[mythtv-users] MythBurn & mpeg2enc segfault

[Mark Schuren]

Yes I also have problems with segfaults using mythburn.

Relevant mythburn log entires:

/usr/src/mythburn/scripts/mpeg2cut-px.sh: line 104: 31325 Illegal 
instruction     nice -n 19 mplex -o ${outfile} -f 8 ${base}.m2v 
${audio} >/dev/null

and

/usr/src/mythburn/scripts/createscenemenu.sh: line 360: 32027 
Segmentation fault      nice jpeg2yuv -v 0 -n $framerate -I p -f 
$framerate -j ${tempdir}/sceneselection${index}.jpg
    32028 Illegal instruction     | nice mpeg2enc -q 2 -a 2 -v 0 -n p 
-f 8 -o ${tempdir}/sceneselection$index.m2v

My version of the mjpegtools is 1.6.3, all crashing tools are from that 
package it seems.

Here's the complete part where things go wrong:

lots of following errors, including also in mpeg2enc:

/usr/src/mythburn/scripts/createscenemenu.sh: line 360: 32027 
Segmentation fault      nice jpeg2yuv -v 0 -n $framerate -I p -f

Any ideas anyone? I'm using mandriva 2006.0 with mythtv,
mjpegtools and almost everthing else from the mandriva/plf
rpms. Never had mythburn working previously. No idea where
to start my search for the reason... Should I get a different
mjpegtools package or compile some of the stuff myself from
sources?

Help!

Mark
