[MPlayer-users] how to use mencoder?

[Joshua N Pritikin]

i'm trying to use MEncoder 0.90pre5-3.0.4 on Linux 2.4.18 i386.

i have a Sony Digital Video avi file which plays fine with mplayer.
i want to transcode it into something else .. mpeg4 or indio5 or whatever.
However, when i try the obvious thing it doesn't work:

mencoder test2002.07.05_14-46-48.avi vcodec=mpeg4 -oac copy -o movie.avi
