For video you would want to use the video hardware available, so
re-using the video widget in Totem would be the best choice.  This uses
Xine or GStreamer as the backend and will talk with your video hardware
for you.

In fact, if all you want to do is watch video, Totem comes with a small
application ("Vanity") which simply streams video from a camera into a
window.   At least this could be a starting point for your code.
