[MPlayer-users] mencoder problems with vivo

[Nate Eldredge]

Using mencoder from cvs just updated, on a Linux box.

I have a vivo file which mplayer plays without trouble.  I would like
to re-encode it to a different format (say divx4).  If I do something
simple like

mencoder -o foo.avi foo.viv

I get an avi file with no video, only a flash of green at the start,
and the sound is twice too fast.

I have an mencoder binary from around March 30.  With it, the same
command line gives a file that has correct video, but still the
too-fast audio.

This vivo file seems to have a sound track which is 16000 Hz, 16 bit,
mono.  As the output file has a stereo audio track, this seems a
likely suspect as to where the screwup happens.  I tried "-lameopts
mode=3" but there is no change.

Here is the output of "mencoder -v -o foo.avi file.viv".
