MythTV 0.25 added support for AirTunes and AirPlay for streaming audio and video from Apple iTunes & iOS devices to MythFrontend.

Important.png Note: Please note - AirPlay (and MythTV in general) do not support DRM encrypted videos such as those purchased via the Apple Store. Playback of such content will fail.

Enabling AirTunes

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

You can obtain the key from the shairplay source.

Simply copy the entire section:-

 (and everything inbetween)

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

In 0.25:

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

In iTunes or 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.

AirPlay mirroring icon

Tap the icon to display a list of available AirPlay devices.

AirPlay Mirroring is not supported.

If the AirPlay icon is not appearing in your app tray, it may appear inside supporting applications. YouTube, Pandora, etc will show the AirPlay icon within the app if a supported target device (MythTV in this case) is detected on the network.

In iTunes, AirPlay is enabled by the same icon, which should appear in the lower right corner of the window.

Troubleshooting Notes

Can't Start / Nothing in frontend logs

If you are having trouble getting started, and have tried setting the environment variable (0.25) to no effect, and/or the AirPlay page is not showing up in the frontend settings (0.26), and/or Bonjour information isn't showing up in your frontend console output, it is possible that AirPlay support wasn't enabled when your build of MythTV was compiled.

Of particular note is a peculiarity for Gentoo users: 'avahi' [1][2] is a required dependency, yet the current MythTV ebuilds ignore both the 'airplay' and 'avahi' USE flags. Instead, the 'raop' USE flag must be set to enable AirPlay support.

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

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.
