<span class="gmail_quote"></span>Hi,<br><br>I'm in the process of creating an RTSP client and have run into problems with connecting to the BBC's radio stations. Like vlc, I am using the livemedia libraries to provide rtsp support and have done a fair amount of work getting my client to receive mms streams via RTSP. Both vlc and my RTSP client can connect to most mms urls if you change the "mms://" to "rtsp://", but have problems downloading particular BBC radio stations in this way. So I was wondering if anyone can shed any light on the problems that I'm having.
<br><br>I'm having problems when trying to connect to some BBC Radio WMA streams via rtsp. My current setup is:<br><br>Ubuntu 7.04 (Feisty Fawn), VLC media player 0.8.6 Janus.<br><br>And my problem is:<br><br>running:
<br>vlc mms://wmlive.bbc.co.uk/wms/bbc7/hi_s1<br>succeeds in connecting to and playing the bbc radio stream.<br><br>However when i run:<br>vlc rtsp://wmlive.bbc.co.uk/wms/bbc7/hi_s1<br>vlc fails to connect and i get the following result:

<br><br>--------------------------------------------------------------------------<br><br>I get the same result when i try to play rtsp://wmlive.bbc.co.uk/wms/bbc7/hi_s1 with vlc 0.8.6c running on Windows XP.<br><br>Other streams that show the same problem include:
<br><br>mms://wmlive.bbc.net.uk/wms/radio5/5Live_int_s1<br>mms://wmlive.bbc.co.uk/wms/1xtra/hi_s1<br><br>where simply replacing the "mms://" with "rtsp://" creates a stream that WMP11 can play, but that vlc can not.
<br><br>What is especially confusing for me is the fact that Windows Media Player 11, running on Windows XP successfully connects, using a very similar pattern of RTSP commands (the messages sent during this exchange are in the attached file). I have tried altering my own RTSP client (which runs on Linux) so that it uses an identical sequence of commands to WMP11, but this still results in 400 errors - I can successfully issue the OPTIONS and DESCRIBE requests and get meaningful responses, yet every time i try to issue a GET_PARAMETER or SETUP request after this, I receive a response of RTSP/1.0 400 Bad Request.
<br><br>My own rtsp client is not able to download mms streams, as I haven't and don't plan to implement mms as it's a deprecated protocol. If anyone could shed any light on this problem, or let me know a place where i might get some answers, then please let me know.
<br><br><br>Thanks heaps,<br>Mark Hingston.<br>
