We are using a custom board to capture BT656 input from an NTSC camera. Now we want to capture 16-bit embedded sync signal video from a different camera. The TRM says that BT1120 is supported. I have modified the tvp5150 driver to the below parameters, but I am not able to capture video. I read register 0x4810551c and it shows 0x00030000 which means some error. Is the problem the camera or do I need to modify ISS or the capture driver differently to get things to work? I am using ezsdk version 5_05_02_00.
Thanks for any suggestions,
Kim
