[MPlayer-users] working mencoder now causing floating point exception

Sun Aug 29 16:02:06 CEST 2004

I had a working copy of mencoder. I was using 1.0pre4. mplayer and 
mencoder. When I started having problems, I switched to 1.0pre5 -- no 
joy. :(

All I've done recently is install transcode
    rpmbuild -ta --target=athlon transcode-0.6.12.tar.gz
    rpm -Uvh /usr/src/redhat/RPMS/athlon/transcode-0.6.12-1.athlon.rpm
and add a locale-specific setting
    export LC_ALL=en_CA.utf8

Set revealed the following locale variables:
    LANG=en_US.UTF-8
    LC_ALL=en_CA.utf8

I've removed transcode:
    rpm -e transcode
and played around with the locale variables, starting by removing the 
LC_ALL variable.

Nothing I've done seems to help.
Here is the command I'm using and the output it generates:
mencoder tv:// -tv
