[streaming] RTSP streaming cable box

Thu Sep 29 04:05:53 CEST 2005

I am trying to make an RTSP streaming cable box. I have two computers; one
with a TV-tuner and the other with an internext connection to the other. I
have the server computer setup to rtsp stream and the client is receiving
the stream and playing. The problem comes in when I goto change the playlist
on the server side. The client will freeze the audio and video but if I stop
the feed and start it again, it works fine.

Any help would be appreciated!!

Here is the output:
