      Version 3.1.1 released on github. This is pretty significant - the details are documented but here us a summary.

      ###Version 3.1.0###

      [1] Added support for Windows
      [2] Added automatic detection of operating system (Linux or Windows)
      [3] Added integrated http listener for basic browser based control
      [4] Changed file naming convention to make filenames unique if multiple instances of DuetLapse3 are running.

      An Integrated http listener is available for basic control of DuetLapse3 (not the attached printer).
      The http listener is activated by specifying a port number using the -port option.
      In conjunction with the -host option it provides the following functionality from a browser (or curl or other method of performing a http get).

      http://<ip-address><port>/?command=<valid command>
      

      *Valid commands are:
      start - Starts DuetLapse3 recording if the -stopcmd option was used or after a stop command
      standby - Stops (but does not terminate) DuetLapse3 recording and discards any images capture. Waits for a start command.
      status - returns brief information about the running state of DuetLapse3
      pause - causes DuetLapse3 to temporarily stop capturing images
      continue - causes DuetLapse3 to resume capturing images
      snapshot - causes DuetLapse3 to make an interim video and then continue
      restart - causes DuetLapse3 to stop capturing images, create a video and then restart with a new capture set
      terminate - causes DuetLapse3 to stop capturing images, create a video and then terminate the program. This is the same as CTRL+C or SIGINT.

      Note that depending on your system - it may take several minutes for the http listener to completely shutdown following a terminate request.*

      Note that the http listener will stop responding if DuetLapse3 is run from a command console that is then closed. This will happen even if started in background. To avoid this - use nohup (linux).
      Windows does not have an (easy) equivalent to nohup so you would need to leave the command console open. An alternative if you are on Win10 is to use Windows Subsystem for Linux (WSL) and run DuetLapse as a linux application inside WSL.
      If running in nohup mode CTRL+C cannot be used so you need to send the terminate command (?command=terminate) from the http listener

      Made an accommodation (in 3.1.1) for ffmpeg < 4.2 by using a simpler syntax if -extratime is not used.

        Take a look at the post above. It does not provide a plugin but the http listener makes it easier to control remotely. It looks like the plugins require javascript and frankly - that's not something I want to get into.
        Someone else (with the skills) could create a simple plugin that calls appropriate urls and provide control that way.
        I will create a helper script that proved a separate http listener to remotely start DuetLapse3 - but that's a few days away.

          @stuartofmt Thanks Stuart; I did try installing the 3.04 earlier this weekend following each step but got stuck at ffmpeg install; doesn't return anything when checking version.

          I guess I'm still way to beginner at linux terminal. I'll try again with the new version

            Don't worry - we will get you going.
            I'm assuming you are using a raspberry pi ?

            The latest version should work with the version of ffmpeg that installs by default with the pi. The only downside is not being able to use the -extratime option.

            I'd recommend you reinstall the default ffmpeg and take it from there.
            It sounds like you tried to follow my instructions and the installation of the latest ffmpeg failed somehow? If that is correct then lets try to clean it up and get you back to the default. Try the following in order (I just did this on my pi) 🙂

            cd ~
            sudo apt remove ffmpeg
            

            I'm guessing this will say ffmpeg is not installed.

            Next:

            sudo find / -name ffmpeg
            

            This will may give some output for example:)
            find: ‘/run/user/1000/gvfs’: Permission denied
            /usr/local/bin/ffmpeg
            /usr/local/share/ffmpeg
            /usr/local/share/doc/ffmpeg

            for each of the files / directories - we'll first delete everything for EXAMPLE

            sudo rm -rf /usr/local/bin/ffmpeg
            sudo rm -rf /usr/local/share/ffmpeg
            sudo rm -rf /usr/local/share/doc/ffmpeg
            

            Next make sure everything is at the latest release level

            sudo apt update
            sudo apt upgrade
            

            I just did this on my pi - it was quite the upgrade and took quite a while so be patient.

            Finally, install the standard ffmpeg

            sudo apt install ffmpeg
            

            after that and assuming no errors

            ffmpeg -version
            

            should return a bunch of information.

            Then reboot for luck 🙂

              @stuartofmt aww mate you're a saint; didn't expect such a detailed help.

              I went through those steps and when doing the find it didn't return anything; so I guess it didn't build properly in the first place (I used the cmake last time)

              Seems like everything is installed now; just got to figure out the usage exactly

              Thanks!

                  my knowledge of python is not really available but when i look at this code:

                   #update the layer counter
                      global zo1, zo2
                      zn = getDuetLayer(apiModel)
                      if (cameraname == 'Camera1'):
                          zo1 = zn
                      else:
                          zo2 = zn
                      
                      if ('layer' in detect):
                          if ((not zn == zo1 and cameraname == 'Camera1') or (not zn == zo2 and cameraname == 'Camera2')):
                              # Layer changed, take a picture.
                              checkForPause()
                              logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' after layer change')           
                              onePhoto(cameraname, camera, weburl, camparam)            
                  
                      elif ('pause' in detect and printerState == 'paused'):
                              checkForPause()
                              logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' at pause in print gcode')
                              onePhoto(cameraname, camera, weburl, camparam)
                  

                  So this script can't access to the take picture routine because zo1 and zn is always the same

                  I have now altered the code to:

                      #update the layer counter
                      global zo1, zo2
                      zn = getDuetLayer(apiModel)
                     # if (cameraname == 'Camera1'):
                     #     zo1 = zn
                     # else:
                     #     zo2 = zn
                  
                      if ('layer' in detect):
                          if ((not zn == zo1 and cameraname == 'Camera1') or (not zn == zo2 and cameraname == 'Camera2')):
                              # Layer changed, take a picture.
                              checkForPause()
                              logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' after layer change')
                              onePhoto(cameraname, camera, weburl, camparam)
                  
                      elif ('pause' in detect and printerState == 'paused'):
                              checkForPause()
                              logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' at pause in print gcode')
                              onePhoto(cameraname, camera, weburl, camparam)
                  
                     # global zo1, zo2
                     # zn = getDuetLayer(apiModel)
                      if (cameraname == 'Camera1'):
                          zo1 = zn
                      else:
                          zo2 = zn
                  
                  

                  And for now it works (but i don't know if i have now added a new failure)

                    Hi Sam - sorry you are having problems. The changes you made to the code will most definitely cause problems 😞 That piece of code keeps track of layer changes.

                    Having said that it was my error ...

                    But first - I see you have started DuetLapse with:

                    python3 DuetLapse3.py -port 8181 -duet 192.168.188.36 -detect layer -camera1 stream -weburl1 http://192.168.188.34:8081/
                    

                    You have BOTH your web camera (-weburl1) AND DuetLapse3 on the same port number. This is a no-no. They need to be different. In the next release (I am testing now) - I check to see if the port is already in use and if it is, prevent DuetLapse3 from starting. So please change the -port so that it is on a different and unused port number.

                    Second - on the layer change - yikes! This is definitely wrong and thanks for pointing it out. I must have copy/pasted that portion into the wrong place when I did some 'tidy up' . I will fix that today. If you want to fix it yourself - move the assignment so that it looks like this:

                        #update the layer counter
                        global zo1, zo2
                        zn = getDuetLayer(apiModel)
                    
                        
                        if ('layer' in detect):
                            if ((not zn == zo1 and cameraname == 'Camera1') or (not zn == zo2 and cameraname == 'Camera2')):
                                # Layer changed, take a picture.
                                checkForPause()
                                logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' after layer change')           
                                onePhoto(cameraname, camera, weburl, camparam)            
                    
                        elif ('pause' in detect and duetStatus == 'paused'):
                                checkForPause()
                                logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' at pause in print gcode')
                                onePhoto(cameraname, camera, weburl, camparam)
                                
                        if (cameraname == 'Camera1'):
                            zo1 = zn
                        else:
                            zo2 = zn 
                    
                    

                    In any case, the change to -seconds 20 -detect none is working as it should but that is bypassing the layer check so the change you made has no effect.

                      Thank you for your assistance!

                      My start command is correct duetlapse runs on 8181 and the cam on 8081 😉

                      to your code change the only change i can see is that you have removed the comments is this right ?

                        Sorry - I misread the port numbers , you are of course correct.

                        As to the question on the code change - no.

                        This portion of code

                            if (cameraname == 'Camera1'):
                                zo1 = zn
                            else:
                                zo2 = zn
                        

                        needs to be after this portion (not before - which was the problem )

                            if ('layer' in detect):
                                if ((not zn == zo1 and cameraname == 'Camera1') or (not zn == zo2 and cameraname == 'Camera2')):
                                    # Layer changed, take a picture.
                                    checkForPause()
                                    logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' after layer change')           
                                    onePhoto(cameraname, camera, weburl, camparam)            
                         
                            elif ('pause' in detect and duetStatus == 'paused'):
                                    checkForPause()
                                    logger.info(cameraname+': capturing frame '+str(frame)+' at layer '+str(zn)+' at pause in print gcode')
                                    onePhoto(cameraname, camera, weburl, camparam)
                        

                        NOTE THAT THE INDENTING HAS TO BE EXACTLY THE SAME - Python is very particular in that regard - so be careful as you edit 🙂

                            is it possible to catch those errors in python ?

                              Version 3.2.0 has been release.
                              This is a significant upgrade and other than bug fixes I expect it will be stable for a while.

                              I added a helper program startDuetLapse3 to enable remote start/stop of DuetLapse3 instances using a browser or similar (e.g. curl). This provides a lot of flexibility in that you can have the helper program set to run at boot time and then remotely start / stop DuetLapse3 instances when you need them without having to use additional scripts or SSH into the machine etc.

                              ###Version 3.2.0###

                              [1] Adds the ability to work with startDuetLapse3. See the description here:
                              https://github.com/stuartofmt/DuetLapse3/blob/main/startDuetLapse3.md
                              In summary startDuetLapse3 provides the ability to remotely start / stop DuetLapse3.
                              [2] Changed the shutdown method to reduce low level 'noise' messages.
                              [3] Restructured to provide better efficiency. Typically less than 1% CPU when idle.
                              [4] Fixed a bug that was introduced in the prior version (not detecting layer changes)
                              [5] Made further improvements to the handling of pauses.
                              There are some edge cases where a printer can get stuck in a paused state.
                              The documentation has been updated. See especially -dontwait
                              [6]Added checks to prevent startup with ports that are already in use.

                              I have done a lot of testing but as usual - something may have slipped through the cracks .....

                                is it possible to catch those errors in python ?

                                Yes - it was one of the things that annoyed me too! one of those things that a 1000 google 'fixes' (all different) did not fix 😞 I found a way though 🙂
                                Its part of the 3.2.0 release.

                                Hope I got them all 🙂

                                  @stuartofmt I'm looking forward to testing this and eliminating my auto-start setup. I find my older setup is re-starting multiple times a day, and only noticed it doing longer prints, when the timelapse was only for the last period of time. Kind of sad after a 10 hour print yielded a timelapse of the last 4 minutes...

                                    I hear ya! FWIW - I have "soak tested" this running overnight and into the next day with a small number of seconds (smaller than practical). 10K+ images and it was stable but I'm sure you can find something for me to fix 🙂

                                    Note that it also runs on WIN10 (and maybe earlier ??) as well as WSL (which I like a lot). So if the Pi becomes a limitation there are other options.

                                    Let me know how it works out.

                                        hi,

                                        thanks for your work!! Now i have a question for what is the whitelist ? i get this error:

                                        The short answer is that startDuetLapse.py needs to be in the same directory as DuetLapse3.py AND DuetLapse3.py needs to be at least at V3.2.0 (i.e. the latest version) .

                                        I have never seen this error - but then I satisfy the above :-).

                                        I just tried to simulate it by putting startDuetLapse3.py in a different directory and get a related but slightly different error. So I suspect that you may have an older version of DuetLapse3.py ?

                                        python3 ./DuetLapse3.py -h
                                        

                                        Needs to have this line in its return (up near the top)
                                        Create time lapse video for Duet3D based printer. V3.2.0

                                        The longer answer is this: When DuetLapse3.py is started manually, the various input options are checked for validity (i.e. parsed through a whitelist).
                                        To help prevent misuse and provide a measure of security startDuetLapse3.py invokes the very same code (imported from DuetLapse3.py) BEFORE it tries to start DuetLapse3.py (which then dutifully does the same thing again).

                                        Why bother apparently doing it twice? To help prevent "someone" (not you, someone malicious) from accessing startDuetLapse3 via the http port and trying to execute some arbitrary code.
                                        The original version (proof of concept) just parsed through any old command line. Dangerous indeed.
                                        To feel comfortable - I needed startDuetLapse3 to be very specific to DuetLapse3. One of those defenses (minimal but likely 'good enough') was to use a whitelist. Since it did not make sense to try and maintain the whitelist it in two places - I restructured some of the code in DuetLapse3 3.2.0 to allow the whitelist to be imported. Hence the dependency on versions and location.

                                            Hello,

                                            Trying out 3.2.0 and running into the following issue (below). The print starts fine and captures a handful of images till the connection reset issue. Both the duet and the pi are running on the same wifi subnet, and the duet is the latest firmware version.

                                            running with the following options (have more logs if needed)
