as you can see from log below it wants to open the stream as a file:
2009-09-10 10:47:04.221 Primafila[511:10b] the file path http://cast.voxcdn.net:8000/2917-MP3-RadioIO-Smooth-Jazz-128
There are a lot of APIs in the system that take a URL but only accept
file: URLs. Basically it was decided that URLs are a good abstraction
for passing filesystem paths. So if you see a URL as a parameter,
don't immediately assume that it supports http: (or ftp: or ssh: or
whatever) without reading the docs.
So I don't believe QTMovie directly supports loading movies over HTTP,
much less Shoutcast-style MP3 streaming. IIRC you can open a movie
view directly on a URL, and that supports fetching the contents over
HTTP. I've used that to play remote .mp3 files, but I suspect it won't
work for Shoutcast streams. For those you may need to roll your own
implementation using CoreAudio APIs.
(Is there a QuickTime developer mailing list? If so, you should ask
there, in case my QTKit knowledge is out of date.)
