You're thinking way too much about this.

To add RTSP authentication support (with dialog boxes) to VLC, all 
you need to do is modify the code that calls "describeURL()", as I 
noted in my earlier message.

If there are any other weird RTSP situations which the current code 
doesn't handle, then we can fix this later, if and when we run into 
them.  (But I'm not convinced that these exist in practice.)

That's correct.  VLC (and all other RTSP clients that use the LIVE555 
code) use the "RTSPClient" object to get a SDP description (using the 
RTSP "DESCRIBE" command).  They then use this SDP description to 
create a "MediaSession" object, which ends up getting passed to the 
"RTSPClient" object, to implement subsequent RTSP commands.

The "RTSPClient" doesn't have a "MediaSession" of its own.  It is 
*told* a "MediaSession" (or "MediaSubsession") object, when it is 
asked to send RTSP "SETUP", "PLAY", etc. commands.

But again, you don't need to care about this.  All you need to 
concern yourself with are the calls to "describeURL()".
