if you want to use VLC-player to watch a live camera from a rtsp-address and you are using Firefox then you need to make an adjustment to the Firefox-settings. i found the following instructions in the web here:http://tanwarimran.blogspot.fi/2012/04/ ... -live.html

Configuring Firefox for Streaming Media (Real Player/VLC)
You must install RealPlayer/VLC 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:Open Firefox, and type about:config in the URL bar.
Right click in the main window and select New and then Boolean.
Enter network.protocol-handler.expose.rtsp for the preference name and click OK.
Select false and click OK.
Now Click On the video link and browser says to choose a program to open the link, select real player or vlc player.
Firefox should now be able to correctly associate streaming media with RealPlayer/VLC. To test this, please Open m.youtube.com and click watch video.
if you are uncertain about this don't do it but ask someone wiser to do it for you. (i was foolish-brave to do it myself and didn't make mistakes so i think it is fairly safe.)
open a new bookmark and write on the URL-line about:config
then press enter.
i have already done this but i opened it again to get some pictures of how it looks like. i scrolled down the long list of settings down till i found the networkprotocolls. i right-clicked on the rtsp-line, then select 'new' and set it's value FALSE. this is how the settings should look like if it's correctly set.
after you have done the trick you'll need to restart your Firefox so that the new setting will be valid.
