Displaying captured frame sequence

I'm using Qt 4.6 on TI OMAP. I have custom application that generates video frames in RGB565 format. I would like to display these video frames sequence using Qt. What are my options?

The only way I've come to so far is converting each frame to QImage and drawing it using QPaint.

On the other hand, the board provides v4l2 output device which works very nice. However I did not find any way to display V4L stream and QT widget simultaneously. How can it be done?

Any help would be appreciated. Thanks in advance.
