Camera model
TESLONG Dual Lens USB - TESLONG 8.0mm Dual Lens USB Endoscope 5M Tube Inspection Camera for Android PC | eBay
I bought this as a relatively cost-effective auto-focus endoscope to use as a nozzle camera.
What is the problem?
It works well, but the camera has a slightly strange design whereby there are two lenses - a normal one and a side one. The side one doesn't show anything useful as a result of where it's mounted, so I'd like to only show the main view:
I have it set up in /boot/octopi.txt for a 640x480 resolution, but mjpg_streamer overrides that and uses 1280x480 instead. I'd like to automatically crop the image so only the left-hand half is visible.
What did you already try to solve it?
I read all the options in v4l2-ctl --help, v4l2-ctl -d /dev/video3 -l, /opt/mjpg_streamer --help and /opt/mjpg_streamer -i "input_uvc.so --help", but couldn't see anything that sounded promising.

Checking for VL805 (Raspberry Pi 4)...
- It seems that you don't have VL805 (Raspberry Pi 4).
There should be no problems with USB (a.k.a. select() timeout)
