I wonder how hard it would be to get a MIPI capture device that presents v4l2, I guess it's almost certainly more expensive right now than a Pi Zero.

Anyone know of a SDI or MIPI capture card that works off the shelf with v4l2?

I haven’t tried looking for it and it seems like minimizing latency on the pi 0 is more fruitful and flexible than trusting such an adapter to work. And as you said, cheaper.
