OK, so I re-added CloseCamera/OpenCamera calls so the cam is now locked only for the duration of shots.

Playing with the text props will still crash, so be careful with them. Probably best leave them at the first item.

And I added width/height setting. You need to do this on the "Image Setting" page - and make sure your width is divisible by 2.

I also noticed that you can't compile the driver on buster, as there are changes in libcamera (exposure is a long, not a pointer and a few other things). Then again, it probably won't run the newer cams anyway.
