If you want to use the Control Center for debugging, you have to enable "USB_DEBUG_INTERFACE" in the uvc.h and reinstall driver after downloading the UVC image. For mode details, please read page 16-19 of AN75779_001-75779_0B.pdf
The AN75779 is example source code for 1280x720/30fps/YUV422/8bit data bus width. If you want to use MT9J003, you have to add initial setting at the SensorInit() and 1280x720/30fps setting at the SensorScaling_HD720p_30fps().
Running for Demo,
1. download the UVC image
2. run VirtualDub or AMCAP
3. Select Capture AVI...
4. Select FX3(DirectShow)
For more details, please read page 20-22 of AN75779_001-75779_0B.pdf.
Thanks. This worked (including this in the uvc.h). However I am still having difficulty in getting the video through - probably my sensor initialization values are not appropriate for the MT9J003. Will try to figure out correct initialization params.
