replacement for https://github.com/jacksonliam/mjpg-streamer.git // mjpg-streamer-experimental used from within octoprint.
After upgrading my raspberry pi 4 from bullseye running octoprint-installation (I think, or even the octoprint-image itself), the camera did not work anymore or to be more precise, the camera could not be used properly anymore with mjpeg-streamer.
Something around camera support changing to be about a new library and mjpeg-streamer failing

I also tried to get something working with rpicam-vid -t 0 --inline --listen -o tcp://0.0.0.0:8888 and so
just relaying that to mjpeg_streamer. But that was no fun at all.

- installed picamera2-libraries /-apps (e.g. by issuing
sudo apt -y install rpicam-apps) - camera (not necessarily csi connected, but that was my starting point)

- octoprint-manual-setup described here: https://community.octoprint.org/t/setting-up-octoprint-on-a-raspberry-pi-running-raspberry-pi-os-debian/2337
- maybe the installation on an octoprint-image would also work, but it may be the files have different locations
assuming, the installation was done as described here: https://community.octoprint.org/t/setting-up-octoprint-on-a-raspberry-pi-running-raspberry-pi-os-debian/2337
- copy mjpeg_server_with_capture.py to /home/pi/mjpeg_server_with_capture.py
- EITHER:
- edit /home/pi/scripts/webcamDaemon to include the lines in webcamDaemon at the beginning (which basically keeps the orignal code inactive since the
exit $?skips the rest of the file)
- edit /home/pi/scripts/webcamDaemon to include the lines in webcamDaemon at the beginning (which basically keeps the orignal code inactive since the
- OR:
- just copy webcamDaemon to /home/pi/scripts/webcamDaemon and make sure it is set to executable (chmod)
systemctl restart webcamdto restart the webcamDaemon and to use the new code- copy over haproxy.cfg to /etc/haproxy/haproxy.cfg (or make the appropriate adaptions)
- the new webcam-server is streaming mjpeg on http://WHATEVERIP:8000/stream.mjpg
- haproxy is offering this also (as reverse-proxy) on http://WHATEVERIP/webcam2/stream.mjpg and on http://WHATEVERIP/webcam2/?action=stream
- the new webcam-server is providing jpg snapshots on http://WHATEVERIP:8000/snapshot.jpg and on http://WHATEVERIP:8000/?action=snapshot
- haproxy is offering this also (as reverse-proxy) on http://WHATEVERIP/webcam2/snapshot.jpg and on http://WHATEVERIP/webcam2/?action=snapshot
- adapt the settings for the webcam in octoprint to reflect the new ports (e.g. change STREAM-URL to
/webcam2/stream.mjpgand SNAPSHOT-URL tohttp://127.0.0.1:8000/?action=snapshot)
- if you have followed the installation from above, it should already be working

- make width / height configurable (at the moment just edit mjpeg_sever_with_capture.py)
- framerate-settings perhaps
It seems to run smoothly, and the performance seems to be amazing so far - there is not even a hint of flickering left in the frames (which happened quite a lot in the last weeks).
