@gri I have not yet tested it out on windows, just kubuntu 10.10 and my n900. You would certainly need at the very least Qt 4.7 installed to test it out on any OS. Not sure how QML importing works in windows (since every other OS uses backslashes instead of forward slashes). I may give it a try on windows sometime soon just to see what is up. Also, qmlviewer has a built-in video recording api, and i have figured out how to start recording, i just can't figure out how to keep recording for more than 1 second. Also, your qml app seems way more responsive than mine I wonder if the C++ helps that much.
