I use the adv7441a as a video decoder to capture VGA source from PC. My backend video processor works well with 601 mode to caputre data from adv7441a (which decodes VGA input from PC(the video format is xga or sxga )). Now I want to set the adv7441a in 656 output mode as the new backend video processor can only accept 656 YUV data. And I set the register 0x6B's bit4 to 0 in User map bank. However, the video processor can't capture the YUV data .
The new video processor works well with adv7441a working in 656 output mode while decoding in HDMI or YPBPR source. Is there anyone who can help me about how to set the correct mode of adv7441a to capture VGA source from PC.
