MythTV 0.25 added support for AirTunes and AirPlay for streaming audio and video from iOS devices to MythFrontend.
AirTunes does not work out the box because AirTunes is a proprietary format and is encrypted in order to enable vendor lock-in. Fortunately the encryption key has been discovered which enables use of AirTunes in open source applications such as MythTV.
When starting the frontend, you will get the following message in the log:
RAOP Conn: Failed to read key from: /home/<user>/.mythtv/RAOPKey.rsa
Simply copy the entire section:-
-----BEGIN RSA PRIVATE KEY----- (and everything inbetween) -----END RSA PRIVATE KEY-----
Paste into a new file at /home/<user>/.mythtv/RAOPKey.rsa and restart your frontend.
The correct RAOPKey.rsa file will have the SHA-1 sum
35a168eaecec4d3c31424bba54de5ca0a058c24a. You can check this with the command
shell> shasum ~/.mythtv/RAOPKey.rsa
Enabling AirPlay (video support)
Because AirPlay support is experimental, you have to manually enable it at the command line.
Set the environment variable named MYTHTV_AIRPLAY before starting the frontend from the command line, for example:-
shell> export MYTHTV_AIRPLAY="1" shell> mythfrontend
where shell> denotes the command-line prompt, not something you type.
If you want it enabled for starting MythFrontend from the Finder, run
shell> echo setenv MYTHTV_AIRPLAY 1 | launchctl
and if you want it enabled this way permanently then run
shell> echo setenv MYTHTV_AIRPLAY 1 >> ~/.launchd.conf
