Detecting video playing on device

[guyluz11]

That's a functionality for the software to detect playing videos and their length.

The software should detect playing videos on VLC and on YouTube on the browser.

This way we can add the functionality to send to the hub some computer State packet, and the Hub start a scene in the room compatible with the computer state like watching a video scene.

If we can detect the video length we can decide if this is just a small video or a full movie, for small videos we will not start a movie scene for example.
