Yes - You can using either the default Receiver, a Styled Receiver, or in a Custom Receiver and using the Media Player Library. Of course, you (the owner of the data) must turn on CORS headers for the m3u8 manifest, any sub-manifests, and for the segments and any keys on your server / CDN to support this. This requirement is due to our player being written in JavaScript and running in Chrome on the Chromecast device.
Note - for the Default Receiver & Styled Receiver, the URL to allow CORS from is www.gstatic.com. For your Custom Receiver, it will be the URL where you host your Receiver.
