How to AirPlay Video from QuickTime Player in Mac OS X
You can AirPlay a video directly from the QuickTime movie player in Mac OS X with the latest versions. This makes it easy to send a video that’s playing on a Mac to an Apple TV over the wireless AirPlay protocol, similar to how it works to AirPlay videos from iOS. And because AirPlay is also supported by third party apps and media players like Kodi (XBMC), you don’t have to have an Apple TV to use the feature, as long as another computer or media center is running a compatible AirPlay receiver it can receive the AirPlay video from QuickTime.
