DuetLapse3

@stuartofmt firstly thanks for your efforts to this point!
I agree that an SBC would be required (as it is with DuetLapse at all right now). In addition interaction with the OS, where required, is supported by DSF if the user chooses to take that risk with a plugin (arguably no more risk than installing DuetLapse & dependencies as a third party application). We probably need to do better with how we deal with dependencies such as ffmpeg if a plugin needs them and maybe @chrishamm can provide some thoughts about a good way forward. As far as "c" is concerned we value the work that you are doing so would be happy to support you with the Duet and RaspberryPi elements of such a system in the future if the situation changes.

Yes - Its a glass half full / empty situation from my perspective. Some of the dependency management can likely be done by the plugin, although success isn't always guaranteed. In the case of "failure" the fallback is no worse than doing it manually at the OS level. I'll PM you about the possibility of upgrading my controller to one that supports SBC.
-
@T3P3Tony @stuartofmt The DSF plugin manifest already supports external package dependencies (like
ffmpegin this case). This is the purpose of the optionalsbcPackageDependenciesarray in the plugin manifest (plugin.json). Python/pip dependencies can be specified using the optionalsbcPythonDependenciesarray. -
@chrishamm does specifying the dependencies cause them to be installed, or for the plugin installation to fail if they are not present?
-
@T3P3Tony The DSF plugin service running as root installs them automatically. If the install process returns a non-zero return code, the plugin installation is aborted.

This is good news! To be clear:

I have a Raspberry Pi 4 and MPEG Streamer installed. Does anyone have clear instructions on how to install Duet laps 3? I can't get it to run
or does anyone know Duet Motion https://www.makeit-3d.de/index.php/de/instrumente/duet-motion-zeitraffer-generator.html

sbcPythonDependenciesattempts apython -m pip install xyz?Actually, it depends on what you have in your
/opt/dsf/conf/plugins.json
it uses the commands defined byInstallPythonPackageCommandand with arguments defined byInstallPythonPackageArguments
So it does, per default,/usr/bin/pip3 install {package}This means you can specify a specific version of a module if you need to, such as
"sbcPythonDependencies": ["dsf-python>=3.4.5"]Also what's the difference between
dfs-pythonand "regular" python? What python version is it based on ?dsf-pythonis a module, it doesn't replace python and is based on the python version you have installed on your system.
At the moment python 3.7 at least is required (that's the version installed on DuetPi image) but should work on higher versions. -
Thanks! I’ll be restarting efforts on a Duetlapse plug-in soon.

Have you looked at the documentation here:
https://github.com/stuartofmt/DuetLapse3/blob/main/Documents/DuetLapse3.mdAlso this:
https://github.com/stuartofmt/DuetLapse3/blob/main/Documents/DuetLapse3 Useage Examples.mdIf you can give some insight into where you are at and what is stopping you from proceeding, we can help.
It is relatively straightforward but there are lots of options. Only a few are needed to get started.

@stuartofmt first of all thank you very much for your offered help. I'll try again later and report back.

@Proschi78
When you say that you installed everything. Do you mean that you installed fswebcam?
How do you normally view the webcam i.e independently of DuetLapse ?-host can normally be left out as that is the ip for the web interface to DuetLapse and the program will normally work it out itself.
Are you saying that the second image is what you see on the console when you try to start DuetLapse.? What is the command line you are using ? That output should only occur if there is an invalid option used and it would be reported. This looks like the output when -h is used
Please use -verbose until we get you running properly as the extra info can be very helpful.

Then I only have to specify the printer ip when starting?Ok - so there is a little confusion here - lets fix that
To get started, its best to use minimal options and make sure DuetLapse can "see" the webcam and your printer. Often the "hard" part is sorting out the camera connection since this can vary quite a lot from camera-to-camera.
Lets start with the camera:
You want to use mjpeg-streamer? That should be fine. (Shameless plug https://forum.duet3d.com/topic/23759/videostream)
Using mjpeg (or other) streamer: make sure its set up so that you can view the stream in your browser. What is that url ? you will use it below.For DuetLapse:
The minimum options to start DuetLapse are:
- duet # the same ip address you would use for DWC
- port # this is the port number you want the DuetLapse http server to use
- basedir # not strictly necessary but best to include so as to not clutter the DuetLapse program folderand of course (for now) add:
-verboseNow you need some camera settings. Since you will be using a streaming url you do not want to specify usb. Instead try this (its what I do)
-weburl1 the url (that allows you to stream in browser
e.g.http://192.168.1.1:8081/mjpeg
-camera1 other
-camparam1= "'ffmpeg ' + ffmpegquiet + ' -y -i ' +weburl+ ' -vframes 1 ' +fn+debug"take careful note of spaces and " and 'When DuetLapse starts successfully: You will be able to access it locally using http://localhost:port where port was set with
-portor you can access it locally or remotely with http://ip:port where ip is the ip address if the machine running DuetLapse (this is NOT set as an option).Let me know how you get on.
BTW - I have a new / improved version coming out in the next few days. It simplifies things a bit by allowing the options to be placed in a configuration file and it has a much better UI. Once you are up and running the new version is just a file copy as it uses all the same config settings.

@Proschi78
In both cases you are still using -camera1 usb (either explicitly of by default). This forced the program to try and use fswebcam. In any case fswebcam does not appear the be installed.
In the second example you did not include all the options that I gave in the post above. Mandatory options like -duet and -port are missing, along with others. It cannot work given the command line input you used.
Does putting
http://192.168.178.70:8081/streamin your browser (on the raspberry pi) display the camera stream ? Do this just to make sure there is no network issue e.g. the camera url is blocked).If so - then the options I gave above should magically work
-
no such option: -d pi@RepetierServer:~/Duetlapse $ python3 -m pip -duet 192.168.178.91 -port 8025-verbose -weburl1 http://192.168.178.70:8081/?action=stream Usage: /usr/bin/python3 -m pip <command> [options] no such option: -d pi@RepetierServer:~/Duetlapse $Love my Duet 3 Mini.

I'm not sure what you are trying to tell me here?
pipis for installing python modules. Also - its best to answer / confirm the interim questions so that the person helping knows what you know. Again, you have not included the options I recommended. What you should be entering is this: Note that its all one line.(I recomend you copy/paste)python3 ./DuetLapse3.py -duet 192.168.178.91 -port 8025 -verbose -weburl1 http://192.168.178.70:8081/?action=stream -camera1 other -camparam1= "'ffmpeg ' + ffmpegquiet + ' -y -i ' +weburl+ ' -vframes 1 ' +fn+debug"Depending on whether you have installed the required python modules (it looks like you may have been) then there is no reason why this does not start properly provided (1) the ip address for -duet is correct and (2) -weburl1 when placed in a browser, displays the camera stream.
P.S. you can also try this form. I prefer the one above because it sidesteps some possible issues with certain streaming cameras.
python3 ./DuetLapse3.py -duet 192.168.178.91 -port 8025 -verbose -weburl1 http://192.168.178.70:8081/?action=stream -camera1 stream
