JW 7.9 brings a major refactor to Casting support that aims to make integrating with the popular second screen experience even easier. You are no longer are required to register with Google and you do not have to set up a custom receiver application. Instead we have integrated directly with the default receiver application provided by Google. This allows more video formats to be supported like MPEG-DASH and provides a much quicker setup time to Cast.
JW 7.9 also adds support for AirPlay directly within the player controls, allowing viewers to watch videos on AirPlay-supported devices like AppleTV.
