[Live-devel] Failed authentication notification?

This is something that the current code doesn't handle very well, 
unfortunately.  For now, you can do what VLC's LIVE555 interface code 
(see "modules_demux_live555.cpp" in the VLC code) does: Look at the 
result of "describeURL()" call.  If it's NULL, then get the error 
message (using "getResultMsg()"), and parse it to get the RTSP 
response code.  Then, if that response code is 401, then prompt/get 
your username,password, and retry the "DESCRIBE", using either 
"describeURL()" with a filled-in authenticator, or using 
"describeWithPassword()".

Ugh - this is gross.  It's yet another thing I'm going to have to fix 
when I rewrite the "RTSPClient" class.
