I think it has dependency on openGL support in Qt and hence on OpenGL too. Does it has any Qt 4.6 specific things also. As of now I am using Qt 4.5 and without OpenGL.

I was very much interested in seeing the application, to understand what it does, but did not spend time in compiling openGL.

By the way I could compile qvideo part alone also. While getting the video thumbnail, do you look for a meaning ful frame to be saved as a thumbnail?
