[Live-devel] Can't connect to BBC Radio WMA streams via rtsp

Thu Sep 13 01:55:25 PDT 2007

Hi,

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.

I'm having problems when trying to connect to some BBC Radio WMA streams via
rtsp. My current setup is:

Ubuntu 7.04 (Feisty Fawn), VLC media player 0.8.6 Janus.

And my problem is:

running:
vlc mms://wmlive.bbc.co.uk/wms/bbc7/hi_s1
succeeds in connecting to and playing the bbc radio stream.

However when i run:
vlc rtsp://wmlive.bbc.co.uk/wms/bbc7/hi_s1
vlc fails to connect and i get the following result:

--------------------------------------------------------------------------

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.

Other streams that show the same problem include:

mms://wmlive.bbc.net.uk/wms/radio5/5Live_int_s1
mms://wmlive.bbc.co.uk/wms/1xtra/hi_s1

where simply replacing the "mms://" with "rtsp://" creates a stream that
WMP11 can play, but that vlc can not.

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.

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.

Thanks heaps,
Mark Hingston.
