[MEncoder-users] Mencoder segmentation fault

Hello,

I have a script that uses mencoder and mplayer(Clip Share PRO) I've
installed everything that was necessary and dependent on Red Hot
Enterprise Linux 4. But I've run into some errors I don't know how to
fix because I don't know what this Segmentation fault means in this case.

Following code from the script I've executed mencoder directly in shell
and got this output:

[OUTPUT START]

generate
INCORRECT files in the presence of B frames. Moreover, due to bugs MPlayer
will play these INCORRECT files as if nothing were wrong!

Segmentation fault
[OUTPUT END]

Does segmentation fault have something to do with audio? It appeared
just after mp3 audio was selected. I have installed latest lame MP3
(LAME 32bits version 3.97)
Do you have any ideas how I could fix this, or any advice?

Hope you can help me with this.

Thanks,
Sofija Blazevski
