I just adjusted my video card to output 60hz instead of 59hz and the input is now detected.
pi@raspberrypi:~ $ pivideo –port i2c1 –query all
PiCapture HD1 is ready
Active video: Mode 1
Selected video source is: hdmi
Active video source is: hdmi
Raspberry Pi camera port is not active
Video processor firmware version: 07
I was able to run the following command to generate a still image.
pi@raspberrypi:~/picapture $ raspistill -o cam.jpg
pi@raspberrypi:~/picapture $ ls
Here is the picture… it’s not quite what I expected, but I’ll take it: https://i.imgur.com/ImJ6UMe.jpg
While the raspivid command in the docs did not work for me (complained about invalid arguments), I was able to successfully generate a 10 second capture with the following.
raspivid -o video.h264 -t 10000
I’m not a video guy, but the sensors or something change the colors/hue of the video as the input changes. For example, when I opened file explorer the capture gained an orange tint.

I think it’s safe to say it works on the rpi4, but we (or at least I) need better documentation of raspicam/raspivid to optimize the capture.
Bonus pic of my pi!
