To Display Video Frame on QML

bts-007

I am using opencv to display video frames from web cam on Qt gui. Now I have planed to display it on QML window(without Qt gui). I was trying to use qdeclarative view but I didn't succeed.
I am attaching the source code for displaying the video on label. In the code I used label (labelInputVideo) and push button to start the frames. Is it possible to display qimage directly on qml.
Thanks in advance

So. Have you managed to do that? I am trying it too with no success. :(
