This is a collection of bits and bobs that make running Octoprint a tad easier.
The most notable component is webcamd which is a minimalist drop-in replacement for mjpeg_streamer.
- Octoprint appends a seemingly-random session ID to the camera URI, which confuses the hell out of
mjpg-streamer mjpg-streamerdoesn't appear to be capable of handle multiple simultaneous streams, resulting in the infuriating403: Forbidden! frame already senterrormjpg-streameritself is complete overkill here
webcamd is based on Igor Maculan’s “Simple Python Motion Jpeg” daemon. It has been reworked to run under python-3.x, accept command-line arguments, to fine-tune the webcam streaming experience.
The user running webcamd must have sufficient access to the webcam device. On most Linux systems, this is as simple as adding the user to the video group. Otherwise the daemon will have to be run as root, which is NOT recommended.
webcam@.service is a systemd unit file for webcam.py.
haproxy.cfg is a configuration file for haproxy that actually works with non-ancient versions of haproxy, and enforces SSL connections to Octoprint.
$ pip install .
$ python3 -m webcamd
$ webcamd --help
Open the following file and copy these contents:
/etc/systemd/system/webcamd.service
