Video clips in Firefox - "RTSP is not a registered protocol"

Clicking on a video clip at C-SPAN.org in Firefox produces this error message. In Konqueror there is no problem - the streaming MP3 clip loads into its linked application.

What is RTSP and how can this be fixed?

Thanks in advance.

Okay I've worked out that RTSP is an established protocol (Real Time Streaming Protocol) which points to .ram files. It must be established because it's used everywhere on C-Span.org.

Still can't work out how to get Firefox to recognise it and let me access my .ram files.

Ideas..?

Okay, here's the solution. This should really be on the Firefox and RealPlayer sites.

Quote:

All internet addresses which begin with rtsp:// are to be opened via RealPlayer. Let's tell our browser to do so.

We have to create (only if doesn't exist yet) a file called user.js in the user's Firefox directory and add some lines. Mine is located at ~/.mozilla/firefox/1yxw9wmb.default/user.js. It should be put in the same directory where prefs.js is.

user_pref("network.protocol-handler.external.rtsp", true);
user_pref("network.protocol-handler.app.rtsp", "/usr/bin/realplay");

And then say yes to the dialog box that pops up the first time you call up using RTSP.

This, simpler solution may also work for some.

Quote:

add line:

user_pref("network.protocol-handler.app.rtsp","/usr/local/bin/realplay");

to file:

prefs.js

You can do this a bit easier by using "about:config".
Type "about:config" in the FireFox address bar. (no quotes)
Right click and select:

new>string

Call it:

network.protocol-handler.app.rtsp

Hit enter, then call the string:

/usr/bin/realplay

or for me:

/usr/local/bin/mplayer

It only takes a couple of seconds.

Thanks for that auditek747.
