[Mplayer-dev-eng] MPlayer SIG11 on seek with unknown codec

It's the Question that drives us, Arpi :

Yes. And this problem exists here, I converted az mpeg1 to divx with
ffmpeg, without audio (fucken piece of code - doesn't detect the mpeg1
video or audio stream, depends on file.. should I write to ffmpeg-devel or
this is a know weakness?).. Nah compiling with -g ..

Meanwhile.. ;) What program can multiplex audio+video streams in one AVI on
Linux ? I don't feel starting vmware...

It also segfaults when -vo x11 -vfm 4 , but then it's ofcoz at rgb :
(gdb) bt
