[MPlayer-advusers] Mencoder + lavf == BOOM !

[Guillaume POIRIER]

Hi there,

A command such as:
mencoder input.movie -o 2.flv -of lavf -ovc lavc -oac lavc -lavcopts vcodec=flv

or any command line that uses lavf produces a SIGFPE.

Here is the log+backtrace

I'm gonna see what I wan do to narrow down the problem, but I can say
for sure that mencoder + lavf used to work (an 18-wheeler full of cola
ahead!)
