We’re working with a custom PCB that connects a composite video camera to an ADV7280A-M and then outputs MIPI-CSI2 to a Raspberry Pi 4.
We’re using the official Raspberry Pi Linux driver:
and took inspiration from this project:
github.com/.../ADV7280-Raspi-shield
The video stream works — but with certain analog camera sources (for example, Framos CVBS modules) the image is shifted vertically:
the bottom ~20 lines of the picture wrap around and appear at the top, as shown below:
text seem to have weird colors:
With other cameras the image is perfectly aligned, so the issue might depend on the input signal timing.
Custom PCB using ADV7280A-M (8× CVBS inputs, MIPI CSI-2 output)
Connected directly to Raspberry Pi 4 Model B CSI port
Kernel: rpi-6.12.y, using stock adv7180.c driver
No modifications to driver except input selection via sub-device
