CORS and Chromecast
All resources not hosted by Ooyala (video, audio, images, closed captions, css, js, etc.) that are used with your Chromecast or HTML5-based playback must have the appropriate CORS headers configured. If your resources do not follow the CORS standard, your player will not function correctly and may break when trying to access files across domains.
You must set up CORS enablement on the CDN that you use for content serving. For information on how to enable CORS, see http://enable-cors.org/ or talk to your hosting provider or vendor.
