Casting and AirPlay

JW Player is Google Cast Ready in all editions. This document will cover the functionality currently available and will walk through how to set up a JW Player to be Google Cast-Ready so your viewers can start enjoying content on their big screen! 


Casting allows viewers to send videos to a different screen while using their device as a remote control. Casting is supported in Google Chrome (Android and Desktop) via Chromecast and in Safari (iOS and macOS) via AirPlay. Casting is not supported in any other browser.  Once the JW Player detects a Cast Ready device or an AppleTV on the network, either a Cast icon or AirPlay icon appears in the control bar to let viewers know they can display their content on a TV. The JW Player within the browser becomes a remote control for viewing media on a TV screen.
