Configuring Firefox for Streaming Media (Real Player)

You must install RealPlayer to open urls with the RTSP protocol (rtsp://) .

Streaming media often uses the RTSP protocol (as evidenced by the link itself, rtsp://address). Firefox does not know how to handle this protocol natively. This can result in the error RTSP is not a registered protocol when you try to access streaming media on the web.

There are several ways to correct the error. We recommend adjusting the Firefox configuration settings by adding an entry for the RTSP protocol:

1. Open Firefox, and type about:config in the URL bar.
2. Right click in the main window and select New and then String.
3. Enter network.protocol-handler.app.rtsp for the preference name and click OK.
   
4. Enter /usr/local/RealPlayer/realplay and click OK.
   

Firefox should now be able to correctly associate streaming media with RealPlayer.
