A simple example of Samsung Internet's 360 degree video playback, enabled by
adding dimension=360 to the type attribute of the video tag.
<video src="paris-by-diego.webm" type="video/webm; dimension=360;" poster="poster.jpg" width="100%" controls="true"></video>
In Samsung Internet v4.2+, press play and then the fullscreen icon, to play the video in 360 degree mode. Now you can rotate your phone around to change the view.
