DuetLapse3

stuartofmt

@stuartofmt I think I will load pi os on my webcam server and install motioneye on top of that. That way I can use videostream, and it will be a newer version of motioneye.

What type of camera do you have? Is it USB? Or is motioneye embedded in the camera itself and provides http access ?
The reason I ask is that you likely don't want motioneye and videostream both. One or the other.

osterac

@stuartofmt it's a pi 4 with 2 USB webcams. I'll hold off with videostream then.

Once you get the resolution set correctly (with motioneye) you should be fine.

I'm working on DuetLapse as a plugin (The DuetLapse code will be common.) . I'll add in the fixed duration option as part of that effort. Fitting it in with other things at the moment - so could be a few weeks .

osterac

@stuartofmt A few weeks isn't long at all! I checked the stream from motioneye by streaming it to VLC and taking a snapshot. It is indeed streaming at 720p regardless of what resolution I set. It's a cheap webcam, so that probably has something to do with it. If I plug it into my PC it will run at 2k, albiet not very well. I may just have to get a better webcam. I really appreciate all your help. Looking forward to that plugin too.

I have a Logitech c615 streaming a different view of the printer, so I'll probably check to see if the resolution is correct on that one. I would use it for timelapses, but the auto focus is horrible and my other cam has manual focus, which I prefer. Although the auto focus is adjustable via ffmpeg parameters, I haven't been able to get that to work with motioneye.
It's been nice chatting with you. I'll let you know if anything else comes up.
Thanks so much!

@stuartofmt Yes they main point from the front end is it brings it into the structure of plugins which ease installation (and potentially discovery by users, once the plugin repository is more used).
<snip>
All that said, the most immediate benefit appears to be with a DWC plugin for the UI to ease installation and discovery.

I looked closely at the practicality of offering a plugin version of DuetLapse3. I received a lot of help from others and did make some progress.

I've decided to abandon this effort for several reasons:
a) It would would only work for SBC.
b) The dependencies in DuetLapse3 inevitably require interactions with the operating system that would not be avoided with a plugin.
c) I do not have a SBC platform and could not properly test.

Having said that - I have made some improvements to DuetLapse3 which I will release soon. These including the ability to use a configuration file to set runtime options.

T3P3Tony

@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.

chrishamm

@T3P3Tony @stuartofmt The DSF plugin manifest already supports external package dependencies (like ffmpeg in this case). This is the purpose of the optional sbcPackageDependencies array in the plugin manifest (plugin.json). Python/pip dependencies can be specified using the optional sbcPythonDependencies array.

T3P3Tony

@chrishamm does specifying the dependencies cause them to be installed, or for the plugin installation to fail if they are not present?

chrishamm

@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.

@chrishamm

This is good news! To be clear: sbcPythonDependencies attempts a python -m pip install xyz ?

Also what's the difference between dfs-python and "regular" python? What python version is it based on ?

Proschi3D

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

Actually, it depends on what you have in your /opt/dsf/conf/plugins.json
it uses the commands defined by InstallPythonPackageCommand and with arguments defined by InstallPythonPackageArguments
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-python and "regular" python? What python version is it based on ?

dsf-python is 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.

@Falcounet

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.md

Also this:
https://github.com/stuartofmt/DuetLapse3/blob/main/Documents/DuetLapse3 Useage Examples.md

If 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.

Proschi3D

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

how can i start Lapse ?

stuartofmt

@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.

Proschi3D

@stuartofmt i usually use mjpeg stream to see the camera in the DWC

I installed fswebcam.
but would like to use mjpeg streamer for that.
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 folder

and of course (for now) add:
-verbose

Now 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 -port or 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.
