I am using the ADV7181D to convert CVBS/S-Video into an 8-bit BT.656 4:2:2 YCrCb 27MHz stream with embedded H,V,F codes. This stream is fed to an FPGA that contains an H.264 video compressor that appears to require video frames that are exactly 720x480 pixels. The ADV7181D device is currently producing video frames that are 720x506 pixels. Can the ADV7181D be configured to output frames that are exactly 720x480 pixels?
My ADV7181D is configured as follows:
