Having trouble setting up mediastreamsegmenter on Mac OS X 10.6

Question

Hello,

I'm trying to use Mac OS X 10.6's mediastreamsegmenter to take the audio input of my mac and turn it into a stream that I could listen to on the iPhone.

I've read this and the related man page:

http://devworld.apple.com/library/ios/#technotes/tn2010/tn2224.html#MEDIASTREAMSEGMENTER

but when I do something like this:

mediastreamsegmenter -s 3 -D -f /Library/WebServer/Documents/stream localhost:8080

no files appear in the 'stream' directory and when I try and use QuickTime Player X to connect to localhost:8080, no go.

What am I missing here?
