Comment 55 for bug 938180

Let's have a look to Youtube.

I think it suits to be implemented like this:

http://doc.qt.io/archives/qt-5.5/qtwebkitexamples-webkitqml-youtubeview-example.html

Probably there is a way to catch the audio stream using QAudioInput.
If we pair this with a last.fm view, it could be really slick, because last.fm is able to redirect to youtube, spotify, or amazon music.
