No.  In princlple, all RTP media players need to first receive a SDP 
description that describes the stream.  However, VLC is able to guess 
the media type of some streams (e.g., MPEG Program Streams and MPEG 
Transport Streams) without a SDP description.  However, that won't 
work for most media types.

In other words, you're relying upon a hack that's specific to VLC.
