Practically impossible, the st->priv_data value would clash (it's a
RTSPStream for RTSP and a RMStream for RM), I'd have to change it in
every single function call... I'd love to do that, but it's not
clean...

Unless we come up with a way to assign multiple priv_data fields to a
single AVStream or something along those lines. (?)
