Mplayer is the swiss army knife when it comes to multimedia. Sometimes you want to save those streams so that you can listen to them for example in you MP3-player. No problems using mplayer. Find out the URL for the stream to download. It looks something like this:
rtsp://my.domain.net/streaming/media.ra
rtsp://my.domain.net/streaming/media.rm

Sometimes the URL:s are contained in a ram-file, then just download the file:

wget http://my.domain.net/streaming/media.ram

Checking the contents of the file should reveal something similar to the links above, ie:

rtsp://my.domain.net/streaming/media.ra
rtsp://my.domain.net/streaming/media.rm

To download let mplayer do the work:

mplayer -dumpstream rtsp://my.domain.net/streaming/media.ra

This will download the media and store it in file called stream.dump. Convert this file to wav format using mplayer again:

mplayer -o pcm stream.dump

This in turn will generate a file named audiodump.wav. In this example I use lame to convert the file to MP3:

lame –tt “Title of track” –ta “Artist name” audiodump.wav example.mp3

Tada!
