disconnection I was looking to trigger an action when I connect to shairport. Basically, I want to switch on the stereo when I start playing music over shairport (and I want to switch if off when I stop streaming). Because my set-up will be different than any other set-up, I thought about making it generic. Two new command-line options --play_prog and --stop_prog take one argument: the command line to start when the first connection is made or when the last connection quits. Example: $ shairport.pl --play_prog="amixer set PCM 100%"
ShairPort v0.05

What it is
This program emulates an AirPort Express for the purpose of streaming music from iTunes and compatible iPods. It implements a server for the Apple RAOP protocol. ShairPort does not support AirPlay v2 (video and photo streaming).
It supports multiple simultaneous streams, if your audio output chain (as detected by libao) does so.
How to use it
perl shairport.pl. See INSTALL.md for further information.
The triangle-in-rectangle AirTunes (now AirPlay) logo will appear in the iTunes status bar of any machine on the network, or on iPod play controls screen. Choose your access point name to start streaming to the ShairPort instance.
Thanks
Big thanks to David Hammerton for releasing an ALAC decoder, which is reproduced here in full. Thanks to everyone who has worked to reverse engineer the RAOP protocol - after finding the keys, everything else was pretty much trivial. Thanks also to Apple for obfuscating the private key in the ROM image, using a scheme that made the deobfuscation code itself stand out like a flare. Thanks to Ten Thousand Free Men and their Families for having a computer and stuff. Thanks to wtbw.
