What is the problem?
Webcam was working, but I haven't used the system in perhaps 6 months. Powered it up and everything but the webcam is working in Octoprint. Octoprint reports "Webcam stream not loaded"
What did you already try to solve it?
Reading. Since this had been working, I'm unsure where to start.
/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
/var/log/webcamd.log doesn't exist
dmesg has this:

Additional information about your setup (OctoPrint version, OctoPi version, ...)
Version 1.8.2 running on an Orange PI.
mjpg does not appear to be installed, so no mjpg-streaming. Webcamd does appear to be installed but nothing I do seems to kick it off.
[Edit] I found a webcamd.conf and changed video0 to video1. No change except it now shows webcamd already running.
I have no installed any updates since the camera was later
I just tested the camera on my laptop and it works fine.
What additional information do I need to post to help with this?
EDIT: I was able to use ffmpeg to capture from the camera to an mkv file and play it on my PC. I had to remove the 640x480 resolution - I guess it was trying to force it and couldn't.
EDIT 2-4-03 - problem solved. I used "motion", works fine now.
Thanks very much in advance.
