Hi, I though about your problem. Maybe you have a chance to get data by doing some changes in the VIN_REG1. Have a look at VSNC_POL, HSNC_POL and VCLK_POL to match the bt829. My second idea was: Do you use the correct output format of the bt829? It must be 16bit 422 to run with the usbvision driver. You wrote about writing an integrated driver. I think this is not a good idea. I prefer to have one usbvision driver for the nogatech chips that loads the driver for the videocodec it needs. That was saa7111-new for all devices I know and it could be a bt829 driver for your device. The bt829 has an i2c interface similar to the saa7111 ones as the datasheet says. Can you try to write a bt829 driver?
