[MPlayer-advusers] SIGSEGV with ffwmv3 @ ppc

Hi there,

I got a SIGSEGV. I throw it through gdb. following the corresponding
data. It's on a PowerPC running debian. Think it should be the video
codec ([ffwmv3] vfm:ffmpeg (FFmpeg M$ WMV3/WMV9)). Problem is the same
with xv, x11, dga and aa video-output. I'm sorry but I don't have the
time at the moment to check with the verry new cvs version (it's cvs
from 22.8.2005).
