Ubuntu

Error playing audio stream

Asked by Andy Ruddock

Trying to listen to BBC Radio 1 stream, I use the command :
# totem http://www.bbc.co.uk/radio1/realaudio/media/r1live.ram

I get this error :
** Message: Error: Could not write to resource.
gstrtspsrc.c(3157): gst_rtspsrc_try_send (): /play/source:
Could not send message. (System error: Connection refused)

This works on my home machine so I know it's possible. I have realplayer 11 for Linux installed and that plays the stream fine.

Hello

the totem gstreamer plugin can play bbc radio, you dont need realplayer AFAIK...
there is a bug in the current hardy version that gives garbled sound https://bugs.launchpad.net/ubuntu/+source/totem/+bug/217301 and its already fixed (Please download the packages below and install them)

you can download it from:

http://launchpadlibrarian.net/14654991/gstreamer0.10-plugins-ugly_0.10.7.4-1_i386.deb
http://launchpadlibrarian.net/14656337/gstreamer0.10-plugins-ugly_0.10.7.4-1_amd64.deb (for 64 bit)

Regards

Bhavani Shankar.

Downloaded and installed the plugins, but I'm still getting the same error.

I just synced the packages from the machine on which this works to the machine on which it doesn't.
It isn't down to a missing package, but still doesn't work :(

At a terminal, type in:
sudo apt-get install ubuntu-restricted-extras

If this doesn't work, add the medibuntu: http://bapoumba.wordpress.com/2008/05/01/medibuntu-non-free-codecs-for-hardy/
And install the package w32codecs

I'm looking at the strace for this and I see

write(21, "OPTIONS rtsp://rmlive.bbc.co.uk/"..., 551) = -1 ECONNREFUSED (Connection refused)

so I think this could be a firewall problem.
If I do netstat then I see :

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 myhost:59664 rm29.rbsov.bbc.co.u:www ESTABLISHED
tcp 0 0 myhost:37210 rm29.rbsov.bbc.co.u:www ESTABLISHED

which indicates that the realplayer is using http for transport.
In fact, if I disable the use of http for rtsp then realplayer fails also.
As this machine is a laptop I'll take it home to confirm this.

So, is it possible to configure the gstreamer plugins to use http for rtsp transport?

Confirmed that this is indeed the problem. just need to get rtsp over http. Thanks for your help.
