Where did you get the camera module(s)?
Kickstarter
Model number of the product(s)?
IMX519 AF Camera
What hardware/platform were you working on?
Raspberry Pi 3 Model B Rev 1.2
Instructions you have followed. (link/manual/etc.)
Official arducam documentation for driver and utilities
Problems you were having?
I am using the recently released IMX519 AF camera on a pi 3B. My use case is headless as a camera for klipper (a pi controlled 3d printer firmware). I followed the instructions on the product page, and I have the driver installed, and the arducam fork of jpg-streamer installed. The basic setup is working, but mjpg-streamer hits a constant 100% cpu and over time leads the system to a thermal throttle. I am trying to troubleshoot this, and I am noticing some quirks from every other install out there. These are a few issues I see:
Every blog/tutorial refers to /dev/v4l-subdev1 as the subdevice to control focus, but I don’t have that on my system. What I have is /dev/v4l-subdev0, and while it exposes several camera parameters, it does not show any focus settings
I cannot get libcamera-vid to work at all to stream the video. Every attempt ends in ERROR: *** failed to allocate capture buffers ***, and I have tried a few combinations of the command.
The dmesg log from your hardware?

Troubleshooting attempts you’ve made?
I have checked that the driver is loaded, and the camera is active. This is the state of my system
What help do you need?
I have a feeling my setup is missing a driver or a configuration settings, but I am not sure what. This is on a 32bit bullseye system.

I’ve tried stracing the command, but I don’t see an obvious place where it fails.
I suspect my problem is partly because I have some misconfiguration somewhere. For instance, as I mentioned in the OP, I have a /dev/v4l-subdev0 and no /dev/v4l-subdev1, and my subdev does not expose the focus controls. This seems different to what everyone else reports. Is it perhaps related?
I understand, and to be clear, I am not complaining about the lack of hardware accelerated mjpg encoding. I’d like to get a native x264 stream and ditch mjpeg - h264 is a much better format for streaming and all clients can natively process it.
I think an improvement would be to only capture and encode when there is a client to send to. I thought that was what the original mjpegstreamer did with an rpi camera. At least I do not see 100% CPU usage on my other systems running legacy mmal mjpegstreamer (only about 4% when streaming, less when not), only the rpi that is using libcamera seems to use 100%.
I have ended up using this to stream h264 and it only uses about 40% of CPU when there is a connection.
We tested and didn’t find this problem,
Maybe you can comment out gpu_mem in /boot/config.txt and increase dtoverlay=vc4-kms-v3d,cma-128 appropriately
E.g: dtoverlay=vc4-kms-v3d,cma-192

I have a longer length cable (75cms) because my mount on the 3d printer requires a longer cable. This cable has worked well for over 100 hours on the picam v2 and it works for capturing video with the arducam fork of mjpg-streamer. I don’t think the cable is the fault, I am bringing it up since it’s probably the only variable that might be different between my setup and your lab.
These are from my latest dmesg after a reboot with the new config.txt. After glancing through, I see some errors with the wifi chipset (which should be unrelated), and a couple of instances of
vc4-drm soc:gpu: [drm] Cannot find any crtc or sizes
A quick google search tells me I need vc4-kms-v3d for a 32bit OS, I’ll make this change, reboot and test.
