Version of OctoPrint
OctoPrint Version: 1.5.3
When you ran into the problem, did you have diagnostic logging enabled?
Diagnostic Logging was Enabled: No
What were you doing when the problem occurred
- I'm booting the Pi.
- I'm going to the dashboard to see my webcam stream
- I see my parameters are not applied
- I start a print
- I see my parameters are not applied
- I go in Octoprint's "Image preferences" and click "Apply All Settings Now"
- I see my parameters are applied.
Note that in "Custom image preferences", I have all 3 options checked to apply preferences at every possible moments.
What should have happened?
Preferences should be applied right after boot.
What happened instead?
The image doesn't appear with my parameters applied (out of focus, too bright..)

Please consider becoming a patron
If you like this project, please support my work by becoming a patron, and consider adding a 'star' to the repository. It takes a lot of time and effort to maintain the project and respond to issues. The cost of test prints, software, cameras, printer parts, etc. can quickly add up, so every bit helps.
You can find various videos and tutorials by subscribing to my Youtube channel. You can also follow me on Twitter.
Please attach your settings.json file. Looks like your pi is refusing the connection for some reason. do you have any fancy proxy or security added? Also, are you using the loopback address (127.0.0.1) for your webcam?
Nothing fancy added.. I added the settings.json link.
Yes I'm using 127.0.0.1:8080 as camera base address.
Maybe this can help?

I may be wrong but since it's working when clicking Apply settings, I guess it's an issue with the camera initialization or something causing delay before anything can access it...
Unfortunately I don't really know how to debug this :/ Does anybody else have a PI 4 8GB with C920 Pro on Octopi 0.18.0 ?
Does octolapse get any feedback when trying to apply settings? If so, maybe it could run a loop like one try per 10 seconds until successful?
Came here because I'm seeing this issue too. The control panel has the right settings, but needs to be manually changed at least once to correctly apply the focus correctly after a reboot.
I'm getting the same exact issue, with OctoPrint Version 1.6.0 and Octolapse Version 0.4.1. I have a C920S. Any time the Pi reboots, the settings do not apply either on OctoPrint start or starting a 3d print. I have to move the slider and hit Apply before the focus changes before every first print after reboot, and of course save to keep it set.
It does seem like focus is properly retained when it's just OctoPrint restarting, so the issue is specific to the Pi 4 rebooting.
OK, I just got a pi 4, so I will give it a go. The only thing I can think of is that there is a race condition at startup that doesn't happen with a Pi3 or below. Either Octoprint is starting up faster than it used to, or mjpgstreamer is starting slower (or both).
The funny think is I added a retry for this feature (apply settings on boot). It is supposed to try to apply the settings, wait on failure, retry, then double the wait and try again. This happens for, I believe, 2 minutes total.
Will let you know what I come up with.
I have a Pi 4B 4GB and a C920. I'm new to ALL of this... 3D printing, Raspberry Pi, Linux, you name it. But I've learned a ton!
I'm able to enable custom image preferences. When I go to change the camera settings, "switch to custom page" fails, which I find odd, considering @FormerLurker uses a C920 in his video.
I'm hoping this related, but if not, feel free to move this somewhere else. Thanks! :-)
So, my initial testing went OK on the pi 4. I think there must be a firmware change on newer c920s, so I'll just need a copy of input.json from your camera to see what the deal is. Navigate to http://{IP_OF_PI}/webcam/input.json, paste the results to gist.github.com, and drop a link in here. That should allow me to get the detection working.

Mine is the C920S which has newer hardware compared to the C920, if that makes any difference.
Mine is the C920S
It apparently DOES make a difference. I'll get that updated. Note that the page you are getting will contain 100% of the functionality, it just won't have the nice UX I added, which just makes it easier to use.
