RE: Playing the channel from TVTuner

Found it myself here.... http://w3c.github.io/mediacapture-main/#direct-assignment-to-media-elements

I am not sure how seamless transitioning from live to timeshifted would be given that the "User Agent MUST re-run the media element load algorithm<http://www.w3.org/TR/html5/embedded-content-0.html#media-element-load-algorithm>" if the source for the MediaElement changes.

Subject: Playing the channel from TVTuner

Hi

Looking at the TV Control API specification [1] I am left wondering how these "connect" at an application level.

I expect that we will be using an HTML5 video element [2] to present the tuned channel and will interact with that presentation via some "TV Application"

As far as I can see, the TVTuner.stream  is of type MediaStream (defined in [3]) but the src attribute of the HTML5  <video> element is a URL. In MSE [4] there is a createObjectURL() defined for MediaSource, but I do not see anything equivalent in MediaStream.

Could someone provide some sample JavaScript for connecting an HTML5 <video> element to the TVTuner?
