Help! vlc0.8.6e cannot play BBC radio rtsp stream

[yfwong]

Hi!

I attempted to play the BBC radio link (http://www.bbc.co.uk/radio1/realaudio/media/r1live.ram). VLC can stream it smoothly for about 1.5 minutes. Then, the stream stops suddenly and cannot resume again. It shows from the log that VLC cannot receive further data after on.
Any idea?

Thanks everyone for the effort on VLC.

I used Wireshark to observe the network traffic while stream the rtsp stream. I found that the server sent some data packets to vlc and vlc acknowledged the server after that. Eventually, the window size of the ack package decreased for a few second and dropped to zero finally. The server will stop sending data packet from now on.

I searched for old posts and found some users had similar problem. Someone replied that it was caused by some old rtsp codes which will not be updated. I am digging into the code to see the problem. I have no idea where the obsolete code is. Anyone can help?
