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 RSA private key will have the SHA-1 sum
7a07afcdf4cbb5653318a329906afe5367cb8b13. You can check this with the command
shell> openssl rsa -in ~/.mythtv/RAOPKey.rsa -outform der | sha1sum
Or, on shells missing sha1sum, like OS X:
shell> openssl rsa -in ~/.mythtv/RAOPKey.rsa -outform der | openssl sha1
Enabling AirPlay (video support) in MythTV 0.25 and Above
This section only applies to 0.25
AirPlay support is disabled by default, you have to manually enable it at the command line.
Enabling In All Operating Systems
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.
In 0.26 and above, use the frontend GUI,
Setup -> General -> AirPlay Settings
Permanently Enabling in Ubuntu 10.04 and later (0.25 only)
Add this line in ~/.pam_environment
Re-login to load the environment variable.
Permanently Enabling in OSX Finder
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
On Your IOS Device
Enable AirPlay from your iPhone (4S or 5) or iPad directly from the recently used apps section in iOS:
Connect your iPhone or iPad and your Apple TV to the same Wi-Fi network. On your iPhone or iPad, double-click the Home Button to display your recently used apps. Swipe your recently used apps twice from left to right until you see the icon.
Tap the icon to display a list of available AirPlay devices.
AirPlay Mirroring is not supported.
Not seeing AirPlay device in iTunes or iOS device
Make sure your firewall isn't blocking Bonjour request. Bonjour uses port 5353 for UDP. For Windows XP SP2 and later, check http://support.apple.com/kb/ts2235
On Linux/FreeBSD, make sure the avahi daemons is running. On Windows, that the mDNS service is running
A message like the following in your logs would show, you can then lookup the error code below
RAOPDevice bonjourregister.cpp:56 (Register) - Bonjour: Error: -65563

Audio glitched in OS X
When using MythFrontend on OSX, you may not experience perfect audio playback, this issue is linked to a bug with IPv6 in the Qt software framework used by myth (Bug 25634)
Seeking on some streaming content hang the frontend
When seeking on some online content, such as when using the YouTube application, may result in the frontend showing "Searching..." and become non-responsive. You can usually interrupt it by stopping playback on the iPhone and restarting it.
