AirPort Express Streaming Audio From Any Program
Foobaz writes "Until now, the only application that can play audio on Apple's AirPort Express has been Apple's own iTunes. But Rogue Amoeba, makers of Audio Hijack, just released Airfoil, a program that lets you redirect anything to your AirPort Express, like streaming audio from mplayer, RealPlayer, or VLC."
It emits noise after using for ten minutes, unless you purchase the "pro" version
That's just your music. Try this site and see if it helps.
I only came here to do two things; kick some ass, and drink some beer...looks like we're almost out of beer.
They answer that question in the FAQ. Yes, the audio will be out of sync. This can be solved with VLC or MPlayer by manually synchronizing the video and audio. This cannot be solved with DVD Player.app, RealPlayer, or anything else that won't let you decouple audio from video. There's probably nothing they can really do about this.
There are no trails. There are no trees out here.
It probably won't be a problem, for two reasons:
1. It's been in beta for a while, Apple could have easily done something about it earlier.
2. It still uses iTunes. The backend uses the iTunes API to add a local stream to the library and send it to the Airport Express.
What would really make Apple upset is if someone had discovered the key being used to encrypt the audio, but that hasn't happened here.
There is a sync issue with this. It's got to do with the APEX standard and nothing the DEV's can do about it.

However. This is not a problem since VLC and MPlayer can move the sound all around. So just watch your torrents with VLC(which I guess you do anyway) and make the sound be a few seconds early. Easy peasy.

If Apple didn't like it and wanted to be proprietary, they wouldn't have used Real Time Streaming Protocol (RTSP), which is a well documented and supported protocol, as the transport method.
they're the first high-profile implementation of the algorithm that Jon Lech Johansen reverse-engineered:
:D

and yes... this is THAT Jon... the one that got yanked into court for reverse-engineering the DVD encryption. all hail Jon!
what we need now is for mplayer and VLC and the others to implement airport express streaming directly in the media player...

I've been using this solution for playing DIVX files from my laptop (which is connected to my projector, while the audio is routed to AirPort Express) for some time, and works well, thanks to the author's knowledge, and the power of VLC !
...considering that only 3% of all computer users use a mac...
When did we get that extra 1%?
A programmer is a machine for converting coffee into code.
My claims? Considering Apple uses RTSP for it's Quicktime streaming it would only make sense for them to use the thing they know for their other products. Any more proof? Shall I telnet to port 554 on my Airport Express and show you the RTSP signature? How about a Apple Press Release in which they updated RTSP in the Airport firmware. I'm sure Apple always updates protocols not supported by their hardware!
As explained in this blog:
RAOP protocol itself has already been analyzed by DVDJon and its implementation is availabe as an open source C# software called JustePort. RAOP protocol is based on RTSP wrapped with AES and RSA cryptography, on which Apple Lossless files are streamed.
AES and RSA are also open methods in conjunction with RTSP. Seems pretty open to me.
