Janus WebRTC Server (multistream): Streaming Demo

# Plugin Demo: Streaming

### Demo details

This demo showcases the functionality provided by the Streaming plugin. In particular, it provides three different streaming approaches, namely:

1. An on-demand stream originated by a file (a song, in this case): different users accessing this stream would receive a personal view of the stream itself.
2. A pseudo-live stream, still originated by a file (an audio recording of a radio running commentary): different users accessing this stream would all receive the same, shared view of the stream.
3. A live stream, originated by a gstreamer script: as for the pseudo-live stream, different users will get the same feed.

You can try them all within the same session: just choose the stream you're interested in and press the `Watch` button to start the playout. Stopping it will allow you to switch to a different one.

Press the `Start` button above to launch the demo.
