Is AppleTV the only device that can receive AirPlay VIDEO?
Solution 1:
Didn't intend to answer my own question, but I found this March 2011 Bloomberg article:
Apple Inc. (AAPL) is weighing an expansion of its AirPlay audio service to include streaming video from an iPhone or iPad to television sets, according to two people familiar with the project.
Under the plan, Apple would license its AirPlay software to consumer-electronics makers that could use it in devices for streaming movies, TV shows and other video content, said the people, who asked to remain anonymous because the plans haven’t been made public. Apple now only licenses AirPlay for streaming audio. Devices that could be used for video may be available this year, one of the people said.
So apparently the answer is "not yet, but maybe in the future."
Solution 2:
XBMC can also act as an Airplay video receiver so that'll add practically any computer to the list, but as far as I know, they've reverse engineered the protocol, so there are no guarantees it'll continue to work.
Solution 3:
Boxee Box works with AirPlay. You can install Boxee software on many hardware platforms so if the native software can't play Airplay you can always try to change it to Boxee.
Solution 4:
You can Airplay to Amazon Fire, Windows, Mac, or Android devices using Reflector 2. It claims to support sending from iOS 9 devices also (note I personally haven't tested the iOS 9 support yet).
Reflector installs an app that acts as an AirPlay and Google Cast receiver. The app is available for Windows, Mac, Android, or Amazon Fire. Since Reflector supports receiving both AirPlay and Google Cast it can receive audio/video from iOS or Android.
It's from Squirrels, the same company that makes the excellent AirParrot app (which allows you send AirPlay audio and video from Windows and Mac to AirPlay and Google Cast).
