Capture or record a real audio/video (rtsp) stream in Linux
Problem
You want to save (capture) a RealAudio or RealVideo stream to a file for later viewing or listening.
Keywords
Real, RealAudio, RealVideo, capture, record, streaming, stream, rip, ripping, mplayer, Linux.
Solution

mplayer -noframedrop -dumpfile out.rm -dumpstream rtsp://url/to/file.rm

(Michael Carr notes that passing a -bandwidth N option, where N is your available bandwidth may considerably speed up the download; the mplayer manual seems to be unclear about it being bits or bytes, though.)

When the download is done you can watch or listen to out.rm with a media player, like realplay or mplayer.

還沒有試驗，畢竟現在 rm 越來越少了，都是 flv 的天下，：（ 以后也要用到，備份在此
