Hi there! Those changes should only be required on an OctoPi instance. I'm not an mjpegstreamer expert, but I believe the base install includes access to control.htm, which is what Octolapse needs to control the camera. Some changes were made on OctoPi to provent remote control of your camera since lots of ppl use port forwarding when it shouldn't be used. It's possible some additional mjpegstreamer setup is required, but you should be able to test by going to your camera url (something like this - ip_address:8080\control.htm ) and seeing if control.htm pops up. If so, you just need to make sure your webcam url is correct in Octolapse.
Ye but when I go to "myurl:8080/control.htm" i get a yellow line at the top saying:
(null) Http output plugin
Inside octolapse under Camera settings at the bottom is the following:
Custom Image Preferences
Here you can adjust brightness, contrast, focus, pan, tilt, etc. for your webcam. If enabled, these preferences are applied at the start of each print.
It is highly recommended that you take the time to configure these settings since they can make a big difference in the quality of your timelapse, and reduce the required snapshot delay.
And there i can enable it but it does not work. And it actually states that the settings there most likely wont work. But if they most likely wont work, why have them there?
Ye but when I go to "myurl:8080/control.htm" i get a yellow line at the top saying:
This sounds like an mjpegstreamer install or startup issue. I'm not an expert on installing this package since I'm targeting primarily OctoPi users, so this question might be best answered on the mjpegstreamer github page.

I'm not sure what you mean by this. I have only one type of camera to test with (a logitech webcam) for mjpegstreamer, and some of the settings that appear in control.htm don't seem to affect MY camera. However, I strongly suspect these settings work on some other cameras, which is why I left them in there. Not all cameras, for example, support auto focus or pan and tilt, but SOME do (including mine).
Check this link that shows command usage. It looks like the www argument is included. You might want to check your startup script to see if it's there.
@Jonas_Ohrfeldt, You should still be able to change the settings even if you aren't using OctoPi as long as control.htm (which is a part of mjpegstreamer NOT octopi) is working properly.
Also, installing 'by the book' might not include control.htm. Can you post your startup command for mjpegstreamer? I should probably try a manual install of this at some point so I am familiar with setup. OctoPi has spoiled me in this regard.
Part of the problem may be that I don't have a raspicam, and am unsure how it works regarding the control.htm page. However, I saw this in the setup guide you mentioned:
Notice the ./www in there. Does your code look like that (I'm guessing it does)?
I think to debug this 100% I need a raspi cam. I'll add it to the growing list of equipment I need, lol! Hopefully I'll be able to figure it out before the next release.

Yes but since my install of octoprint is on raspbian stretch i dont have the octopi.txt file.
Sure i get the camera to work and can do octolapses. But I am unable to make changes the easy way wich i am looking for.
I can ofc use commands in my script.
I wish i was more experienced in scripting, that way one would actually be able to add all custom settings to octoprint that the raspberry pi camera module is capable of?
Why i got this camera is because most people recommended it.
So since i actually followed the guide to install Octoprint and webcam on a Pi running Raspbian stretch i do wonder where i could find theese settings?
My Guess is that the Webcamdaemon script that actually starts the webcam is the config file ?
And why isnt control.htm supported ? I do not get any snapshot there from my camera. And it looks like it does not load the "plugin".
:the lighting dims:
:drum music fillls the room:
:a voice speaks after the final note:
It is said that the original OctoPi image many moons ago was born straight from the fires of a volcano we call Ubehebe (which is maybe Polynesian for Raspbian Stretch).
Nicely played. I could only counter with my Gryffindor robe.
This might be the part where you use your light saber to slash a message into the wall that the user should start over by installing the OctoPi image. (I think they must have missed the "Heads Up" paragraph in the beginning.)
Well should i take this as your knowledge really isnt there, and the only way to handle it is to goof around making fun of users in need of help?
Foosel who actually wrote the guide on how to install it on raspbian stretch might be able to answer what I initially asked?
Its alot easier to answer "no Sorry we dont know how accomplish what you are asking for, we really dont know much at all. We just copy/paste info that we actually dont know anything about"
Allow people who are constantly fielding repetitive support requests which often (though not on this case) can be answered by using the Search and reading the FAQ a bit of late night fun, will you?
@FormerLurker already gave you something to check. It might be that mjpgstreamer's control stuff doesn't work with raspicams - I honestly wouldn't know because as you already heard we actually disable that stuff altogether in OctoPi for security reasons anyhow and instead recommend configuration via the config file, which is documented in the FAQ and if you followed the guide you can just use the very same file - just create it.
I have tried to search for the answer, i think i mentioned that. And as always, if people would answer to my questions it is done whith free will. I am not forcing anyone to answer. But if they do answer, i would appreciate a more mature approach.
And yes, I tried to find my answers from links and other info in this thread, but I was unable to see what others saw.
Is there a way to download octopi.txt in its full content to see what other settings there is?
If you'd followed the FAQ link that @OutsourcedGuru provided you with you'd already found the contents of that file plus information on how to adjust it.
@Jonas_Ohrfeldt By your own admission you were working from foosel's installation instructions. Here is a screenshot of the very top of that page where she has highlighted in a quotation block the easiest method of installing OctoPrint on Raspbian:
Rather than following that advice, you then plowed ahead and installed it manually and are having difficulties. You wanted the first link on that page for OctoPi in this case. Both she and Guy have tried to make this super-easy.
So forgive me if I take the micky on this one when you suggest that you chose not to follow her instructions.
Does that change the fact that she actually made a GUIDE on how to install it under raspbian.
You are kind of saying to me something like this "dumbasses like you should not be here wasting our time"
And someone in this threads said that I was to search using the search function BECAUSE it was wasting "important peoples(so they think)" time.
Let me ask you, who is actually wasting time here and making this thread alot longer then it needs to be?
If you dont have anything useful to say, it is usually best not to say anything.
And to make something clear. I do want to use my raspberry to more then ONE task. Yo do know that it is possible for a pi to run multiple servers?
Im running multiple servers for home automation, cloud services and such on my raspberry and it handles it like a charm.
It does also run octoprint. Using octolapse was just an unecessary fun option. If you had answered, what I was trying to do, was impossible, then i wouldnt have continued on that track.
People are not born with all knowledge you know, you learn from searching and asking.
Im so Sorry that I joined this forum. I did not know it was more of a comic con hangaround.
