We have embedded the ADV7401 on a card of ours not using the recommended ADV7401 AINx pins.
The following connection were set manually:
We have connected the Y (Y/C) to pin AIN6 and AIN6 is connected to ADC0.
We have connected the C (Y/C) to pin AIN5 and AIN5 is connected to ADC1.
INSEL is set to "CVBS in on AIN1"
The video provided by ADV7401 is OK (colorful) although I do not understand why.
Could someone elaborate this issue?
