/**
* A Video object that takes a previously loaded Video from the Phaser Cache and handles playback of it.
*
* Alternatively it takes a getUserMedia feed from an active webcam and streams the contents of that to
* the Video instead (see `startMediaStream` method)
*
* The video can then be applied to a Sprite as a texture. If multiple Sprites share the same Video texture and playback
* changes (i.e. you pause the video, or seek to a new time) then this change will be seen across all Sprites simultaneously.
*
* Due to a bug in IE11 you cannot play a video texture to a Sprite in WebGL. For IE11 force Canvas mode.
*
* If you need each Sprite to be able to play a video fully independently then you will need one Video object per Sprite.
* Please understand the obvious performance implications of doing this, and the memory required to hold videos in RAM.
*
* On some mobile browsers such as iOS Safari, you cannot play a video until the user has explicitly touched the screen.
* This works in the same way as audio unlocking. Phaser will handle the touch unlocking for you, however unlike with audio
* it's worth noting that every single Video needs to be touch unlocked, not just the first one. You can use the `changeSource`
* method to try and work around this limitation, but see the method help for details.
*
* Small screen devices, especially iPod and iPhone will launch the video in its own native video player,
* outside of the Safari browser. There is no way to avoid this, it's a device imposed limitation.
