Hi all,
is there a possibility to run speed-camera on Debian 11 aarch64 ??

After successful install with speed-install.sh and some changes in config.py, I debugged my problem with

$ ./speed-cam.py

speed-cam.py 11.23  written by Claude Pageau
Motion Track Largest Moving Object and Calculate Speed per Calibration.

    self._handle = _dlopen(self._name, mode)
OSError: libmmal.so: cannot open shared object file: No such file or directory

The libmmal.so error seems to be related to the non 64-bit functional picamera driver

raspberrypi/firmware#1558 (comment)

Under 64-bit 'libcamera' is recommended, but there is also a new version of 'picam' for 10 days, I will try out...

After a lot of tests, I can say, that the issue is related to Debian 11 and Python3 - also with 64 bit architecture.
Works like charm under Debian 10 32 bit

The only error I could find, was during installation script:

Package python3-imaging is not available but is provided by another package
referenced. This can mean that the package is missing, that it has been detached
or is only available from another source.
However, the following packages replace it:
   python3-pil

E: There is no installation candidate for package 'python3-imaging'.

WEBCAM = True
WEBCAM_SRC = 0

These settings have no affect to the error

Hi Claude, thanks for that statement.

The issue is, that I currently use Raspberry Pi OS Legacy Buster.
Yesterday I had serveral installations (from Raspberry Pi OS Lite Bullseye 64 bit down to my current installation Raspberry Pi OS Legacy Buster) and obviously, on Legacy Buster the installation process runs much better.

I have to mention, that my user accout is NOT 'pi', thats why I opened another ticket with "improvements".
I will do a totally fresh install of Raspberry Pi OS Legacy Buster, the 'pi' user and speed-cam and would document the remaining problems here.

Don't worry about... I know, this is a hobby project. I just want to give you some informations to improve some issues.
Regards
Will
