Section 11.8 of the RTSP spec [1] says something about passing parameters
to a media server. I guess this should be a preferred mechanism to do that,
instead of URL parsing (even though the latter is easier to implement). 
 
Example from RFC-2326 :

C->S: SET_PARAMETER rtsp://example.com/fizzle/foo RTSP/1.0
           CSeq: 421
           Content-length: 20
           Content-type: text/parameters

           barparam: barstuff
