Control demo is scripted.

### States

#### Demo

* Execute `demo.control` to deploy the control demo.

* Execute `demo.video` to deploy the video demo.

#### Gstreamer

Gstreamer is installed from the sources, which are fetched from GitHub. We are using `gst-uninstalled`, a environment system much as virtualenv for Python. As we are using many different gstreamer elements, we build all plugins together with Gstreamer.
