dmitri-mcguckin / webcamd Goto Github PK

I installed webcamd from the master.zip file on Rocky Linux 8.8 system.
My usb cam from lsusb: Bus 001 Device 002: ID 1bcf:28c4 Sunplus Innovation Technology Inc.
"v4l2-ctl --list-devices" shows:
1080P Webcam: 1080P Webcam (usb-0000:00:15.0-2):
/dev/video0
/dev/video1

The stream is working, I have it embedded in an Octoprint setup. I do see these exceptions popping up in /var/log/messages. At first I thought it was anytime I switched over to the browser tab where octoprint has the stream showing, but it seems more random now.

Hello Dmitri,

First off, thanks for adding the bits that allow webcam.py to be installed via pip. That is a very useful feature.

However ... I couldn't help but notice that you (undoubtably accidentally) removed the code attribution from the top of the original webcam.py for both myself and Igor.

A quick diff between your main.py and my webcam.py indicates that the differences are primarily cosmetic whitespace changes.

Would you mind restoring the authorship credit to the relevant files? As this code is licensed under GPL-3.0, retaining attribution (no matter how little original code is retained) is generally considered to be good manners.

Thank you very much in advance, and cheers,

-- Chris

Just reinstalled my octoprint setup. This is an Odroid H2 running Alma Linux 9.3. Some colors through the webcam are way off. First picture shows orange parts on my Sovol SV04. Second pic shows them in their normal blue. The pegboard on the wall of my enclosure shows the same thing. Other colors are off as well, green cat 5 cable looks yellow.

Checked with a different webcam and see the same problem.

The image swaps red and blue.
