Can't work with Mencoder & Ubuntu64

[mod]

While I'm still trying to make a working build of Avidemux (here (http://forum.doom9.org/showthread.php?p=896127#post896127)) I'm not able to work with Mencoder.
This is the problem:

I searched with google for this problem but I didn't find any solution. Also tried other builds but same result.

Does anyone here have a solution?

Thanks a lot for the help :)

-xvidencopts fixed_quant=3 threads=2
This should be -xvidencopts fixed_quant=3:threads=2

The problem could be in XviD libraries that do not get changed along with the Mencoder build. Does encoding with lavc work properly?

Thanks for the reply.
The parsing of cline was correct also in the other way.
Sorry if I didn't say, Mencoder doesn't encode not only with xvid but also with other formats.

I'm guessing this could be a problem with your new CPU and either GCC optimization flags or assembly code used by MPlayer/Mencoder. You could probably track the illegal instruction with gdb and the dumped core file (run "ulimit -c unlimited" before running Mencoder if there is no core file) or by running Mencoder within gdb. See A.6.6 in http://www.mplayerhq.hu/DOCS/HTML/en/bugreports_what.html

It is likely that your Mencoder binary doesn't contain debugging symbols and therefore gdb output is not really useful. To examine the problem properly, you need to build your own Mencoder, preferably the latest SVN version, with debugging symbols (./configure --enable-debug=3; make). If you get the same crash with your own compile, you should file a bug report directly to MPlayer/Mencoder users mailing list, following http://www.mplayerhq.hu/DOCS/HTML/en/bugreports.html.

It is also very much possible that the Ubuntu64 packages are simply broken, but you should be able to find that out by compiling the programs yourself.

I have to correct myself: atm I can encode with x264 (the problem is only with video, audio has always worked ok), tomorrow I will try other codecs, maybe I can find the "broken" part.
