Take a look at clientapps/simpleplayer. It fully supports
playback
velocity. It will show you how to control the velocity of
the
playback engine. Playback velocity is on HEAD and 150Cay.
The RealMedia
renderers (plugins) already support velocity. It is only the
Linux
player GUI that does not (yet) support it.
