 An open-source implementation of an AirPlay mirroring server for the Raspberry Pi.
 The goal is to make it run smoothly even on a Raspberry Pi Zero.

 # State
 
 Screen mirroring and audio works for iOS 9 or newer. Recent macOS versions also seem to be compatible. The GPU is used for decoding the h264 video stream. The Pi has no hardware acceleration for audio (AirPlay uses AAC), so the FDK-AAC decoder is used for that.

 There still are some minor issues. Have a look at the TODO list below.
 
-Please note RPiPlay might not be suitable for remote video playback, as it lacks a dedicated component for that: It seems like AirPlay on an AppleTV switches to a standard AirPlay connection when video playback starts, thus avoiding the re-encoding of the video.
+RPiPlay might not be suitable for remote video playback, as it lacks a dedicated component for that: It seems like AirPlay on an AppleTV effectively runs a web server on the device and sends the URL to the AppleTV, thus avoiding the re-encoding of the video.

 # Contributing
 
 I'm afraid I won't have time to regularly maintain this project. Instead, I'm hoping this project can be improved in a community effort. I'll fix and add as much as I need for personal use, and I count on you to do the same!
 
 Your contributions are more than welcome!

 # Todo
+
 * Properly handle timestamps and ntp
   => Smooth playback, low latency
 * Use OpenSSL for the elliptic curve crypto?
 * Bug: Sometimes cannot be stopped
   => Likely deadlock in audio time thread

 # AirPlay protocol versions
+
 For multiple reasons, it's very difficult to clearly define the protocol names and versions of the components that make up the AirPlay streaming system. In fact, it seems like the AirPlay version number used for marketing differs from that used in the actual implementation. In order to tidy up this whole mess a bit, I did a little research that I'd like to summarize here:
