Saving Realplayer Streams
If you want to save a Realplayer-Stream, for example from an online radio, use mplayer. It's as simple as:
mplayer -dumpstream rtsp://stream-url
Sometimes it's a bit tricky to get the right stream-url (starting with rtsp://).
If the stream opens in a realplayer plugin in the webbrowser right-click on
the plugin and choose "copy stream url", then you get an url starting with
http:// for the stream, now use something like curl:
curl http://stream-url
and you should get the right url as output. After mplayer has dumped the
stream just copy the file named stream.dump to something with the fileextension
.ra and you can playback the stream in your realplayer, without requiring `
access to the internet.
