(Sorry for my english) I finally run the VideoEmulation app. I run WebCamBroadcaster on OSX (using QTVideoCapture). When i run the app on the emulator LogCat shows:

And nothing is displayed in the emulator screen.

I was having trouble with this after I upgraded to a new laptop that only has Java 1.6. The QT libraries are apparently deprecated, but you can still make it work by forcing the QTWebcamBroadcaster to run in 32-bit mode. Add the following parameter to your VM options to force it to run in 32-bit mode: -d32 I will update the README.
