I must confess, I don't know how to do it with the "standard" Qt classes.
However, I've developed my own set of capture and video display classes.

A complete application that just captures video and draws it on screen in
real time:
http://code.google.com/p/livepro/source/browse/trunk/devel/app-template/MainWindow.cpp#28

(That app demos both using OpenGL directly and using a QWidget to render
video.)

The low level capture under Linux is done with V4L:
http://code.google.com/p/livepro/source/browse/trunk/gfxengine/SimpleV4L2.cpp

Which is handled by the CameraThread (which uses libav on windows to
capture):
http://code.google.com/p/livepro/source/browse/trunk/gfxengine/CameraThread.cpp

And the video is rendered using a GLVideoDrawable:
http://code.google.com/p/livepro/source/browse/trunk/gfxengine/GLVideoDrawable.cpp

(For actually using that googlecode project, see
http://code.google.com/p/livepro/wiki/QuickStartGuide)

Regards,
Josiah
