Speed-camera on Debian 11/RaspberryPi OS aarch64 #115

will-code-for-pizza commented 2 years ago

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

Under 64-bit 'libcamera' is recommended, but there is also a new version of 'picam' for 10 days, I will try out... https://forums.raspberrypi.com/viewtopic.php?t=335832

You might want to try changing config.py configuration.

Make sure there is NO Webcam plugged in. Raspberry Pi camera should be recognized as video device zero and opencv should be able to read the picamera without loading the picamer python library. Not sure about mmal but I did a test on my RPI using Buster 32bit and it ran OK under the WEBCAM setting and not using python picamera libraries. Give it a try and let me know. Claude

config.py settings WEBCAM = True WEBCAM_SRC = 0

Also if this works and image is flipped, physically rotate the picamera module or RPI 180 deg as appropriate. I have cases with hole for picamera as part of the case. Don't use the USB flip setting due to slow performance

will-code-for-pizza commented 2 years ago

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

My suggestion would be to run under Raspberry Pi OS Legacy Buster. Speed camera works OK on that distro. Currently Bullseye is not supported since the original picamera python modules are Not supported on Bullseye and other distro issues. The new picamera2 module is still under development with no definitive date for production. Also as you have found out a lot of libraries have changed and python 2 is no longer supported. I will not be looking at these issues until the distro matures and I have the time and inclination to review. I have been retired for 16 years and did this project just as a fun coding project. If you want to clone the project and develop your own solutions that support backward and forward compatibility I would be more than happy to review and merge any github pushes.

Regards Claude ..

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

Yes I am aware of the issues new distro's can cause as well as what standard packages and libraries are included/restructured/renamed/ Etc. This has happened before and can cause downstream issues for existing software since they often don't provide backward compatibility. A simple parameter change can often cascade and cause a lot of trouble shooting. System and Python Libraries are usually the main cause.This has happened in the past but seems to be a bigger issue with Bullseye. Python is also going through a transition. At some point I will determine whether I will try to maintain backward compatibility or create a new version for the latest distro. In the past I have tried to maintain python2 and 3 compatibility as well as changes in distro support packages that change eg ffmpeg Claude ...
