I saw this but I was missing all the jack info. I rebuilt mplayer with jack support. I
started jackd per your example:
JACK tmpdir identified as [/dev/shm]
[JACK] cannot open server
Failed to initialize audio driver 'jack'
Could not open/initialize audio device -> no sound.
Perhaps I'm missing a step?

Probably noone needed this precice functionality
yet.
The radio guys have this stuff to see if their streams are still alive.
Ah, here it is:
http://www.aelius.com/njh/silentjack/
Use any player (mplayer, cvlc, gstreamer) with jackd support to decode
your stream or use the usual anything-to-jackd magic to make your
consumer applications work with jackd.
Something like this:
$ jackd -d dummy (won't terminate and will not output anything)
$ gst-launch uridecodebin uri=http://some.stream/ ! \
audioconvert ! audioresample ! jackaudiosink connect=none
$ mplayer -ao jack,port=SilentJack http://some.stream/
1] A tool that can read from an http stream and
write it into a pipe
(maybe mplayer/mencoder)
mencoder is dead. mplayer, vlc, gstreamer and co are alive.
Cheers
