Bad recoding with ffmpeg

["Michelle Konzack" <linux4michelle@tamay-dogan.net>]

Hello*,

I recode from a PHP webinterface with the help of ffmpeg.

My mobil Videoplayer does not support OGM files

The commandline is simply

    ffmpeg -i input.ogm output.mp4

but I get this  output:

So to convert this OGM files I need an extra option, but which?

Thanks in advance
