I don't know if that camera specifically supports live streaming, but you can
see how the simple program like
https://github.com/aqiank/gphoto2-liveview-example works to display a camera
live stream. That particular program relies on the gphoto2 CLI to get the data,
so you'd have to read its code to figure out how to write a self-contained
application using libgphoto2 directly. The API documentation at
http://gphoto.org/doc/api/ will help with that.
