[vlc-devel] RTSP issues in latest vlc (0.9.0-svn-20061010-1313)

Tue Oct 10 17:20:32 CEST 2006

Hello!

There seems to be a bug in VLC. It seems that rtsp username/password 
(issued via the respected command-line switches) are completely ignored 
by the application after a "401 Unauthorized" error is reported and
the client falls back to http.

More info follows:

Stream
======
rtsp://SERVER_IP/broadcast/path/to/file.rm

Players
=======
1. Media Player Classic (with Real Alternative Codec Pack)
2. vlc-0.9.0-svn-20061010-1313 (with Live.com libraries)

Information
===========

1. Using Media Player Classic a connection is established properly.
User has to input rtsp username/password in a pop-up window.
