Capturing RTSP data and placing it into a file

[David Niklas]

Hello,

At:
https://www.startpage.com/eng/protect-privacy.html
there is a link to:
https://www.startpage.com/eng/futuretense.ram
in the section that reads:
"A search engine that remembers little about its users
RealAudio or MP3
National Public Radio"
I copied the link and pasted it into my terminal. I invoked curl on it
and curl got the link. 2 redirects later I found the actual url of the
data to be:
rtsp://mprrm.publicradio.org/5559/news/futuretense/daily/2006/10/02.rm
I invoked curl and got nothing. I tried again using verbose and then
checking curl's return value.

% curl -v -o 02.rm
'rtsp://mprrm.publicradio.org/5559/news/futuretense/daily/2006/10/02.rm'

% ls -sh 02.rm

I am interested in getting the rm data from the rtsp stream, what am I
doing wrong?

Thanks!
