You will have to write your own renderer in this case.
But I'd like to warn you here - Qt seems to be very simple here -
Its designers decided that Qt shouldn't be used for movies
(at least not on slower computers) and they support ONLY 32bits RGB
surfaces - so everything has to be converted into such huge bitmap -
which is moreover transfered several times inside nice C++ pipeline
via several constructors (at least this was my impression - if there are
some Qt experts let's feel free to correct me)
I guess the only way to solve this would be probably some tricky usage
of OpenGL for such widget - but if you want to get fluent efficient playback
Qt is definitely not your friend here...

You could check avirecompress how to show image in Qt window
(samples/qtrecompress/qimagecontrol.cpp)
But as I've said - it's usable only for preview - unless you
have >1GHz box otherwise it will consume a lot of memory bandwidth
for larger movies...
