Traditional iframe based player, can auto size, however aspect ratio of the content will not be maintained, resulting in possible black bars on the side depending on your webpage layout.

Our new player, currently is used for non-interactive viewing or for use on lobby TVs, etc. It will soon replace the existing player with a new interface. This embed code auto sizes to available space. If used on a SPA or dynamically loaded, add a &contentid= parameter with the name of the target div to embed the player into.
