The Amber player has built in support for AirPlay, this means devices with support for AirPlay will have an AirPlay icon available in the player controls, allowing you to cast the video to an AirPlay device.

Note, icon is only showing up when user is on the same network as the AirPlay device and on supported browsers such as Safari.

More information about the AirPlay support in Amber player can be found in the Amber Player Documentation.
