[MEncoder-users] error: cannot find codec (winxp->linux)

[GROG!]

Hi all. This is my first time posting here & I'm a real NOOB when it
comes to video encoding, so please be kind :?)

I'm trying to use mencoder (dev-CVS-050928-16:38-3.4.2) on my winxp
box to resize videos to play on my zaurus handheld (running linux)
using mplayer (1.0pre6-3.4.3).

The encoding seems to go fine. I'm using this command that I took off
of an old howto site, so I'm not sure of the verasity of all the
options:

    c:\progra~1\mplayer\mencoder infile.avi -srate 24000 -ofps 15
    -sws 2 -ovc lavc -vf scale=320:240,eq2=1.0:0.6:0.1:0.7 -lavcopts
    vcodec=mpeg4:vhq:vbitrate=150 -lameopts cbr:br=64:mode=3 -vop
    scale=320:240 -oac mp3lame -o outfile.avi

But when I try to play the file on the handheld, I get audio but no video. I
noticed this error:

    Cannot find codec matching selected -vo and video format 0x34504D46.

Now AFAIK mplayer has the mpeg-4 codec built in:

    $ mplayer -vc help | grep -i "mpe*g[-\. ]*4"

        [QuickTime.qts]

But when I run 'mplayer -v outfile.avi', I notice this:

    ==> Found video stream: 0

    ===========================

Now I found references in the mencoder.devel list about there being an
inconsistancy with FMP4 between windows & linux codecs. Could this be
the problem? Is there any hope of me being able to convert my videos?

Thanks in advance.
