DuetLapse available for Alpha testing

[Danal]

Well, drat, I obviously have gaps in my test cases.

Will be fixed and upload in 20 min or so.

[Danal]

OK, now fixed.

While I was there, I added the ability to press Ctrl+C one time, while waiting for pre-start or print running, and it will move directly to making a video. In other words, if you wish to end it before the print ends, and still want the vid, press Ctrl-C once.

I edited the code and removed the whole camparms thing and hardcoded the call to fswebcam to test it. Having some issues now of other kind (that's a fedora vm with usb camera connected trough vm-terminal as the camera with good view of the printer is on usb on my desktop so I can monitor during testing phase ) so don't have the test video yet but so far it seems to be working. Anyhow the device and resolution are hardcoded? Why? fswebcam will use -d /dev/video0 as default anyways so I don't see reason for you to hardcode it and if user want to use other one like i420:/dev/video1 you can't pass that parametar to fswebcam as you already hardcoded video0, also resolution, what if I want 1280x960 as that's native to C270, you hardcoded 800x600 ?

Maybe let fswebcam use default values (low res, video0 ..) and show in help example how to get some decent values (higher res etc..)

[arhi]

@Danal that's a nice feature (ctrlc once)
I'll test the new code asap

Yeah, you have very valid points. I THOUGHT I did the minimum to get a usable image... but it really looks like I should have let more things default.

I can do it two ways:

1. Remove everything I can and risk the auto stuff not working for a true "newbie" for some reason or another

(Probably going to do this... low risk...)

2. Have camparms replace EVERYTHING, except the file name.

[Danal]

OK, I did a little of both. Removed quite a bit from the 'defaults', AND changed it so that if you specified 'camparms -parms' the only thing that is added is the filename.

And, introduced "vidparms -parms '. Works the exact same way, except it is passed to ffmpeg.

Ready for test right now.

@Danal I have been using your tool for a week now and there is one thing which would be nice.
I have to log into the Pi to send the DuetLapse.py -camera pi - detect layer -duet 192.168.0.7
All this Pi does is run the TimeLapse software.

When it has finished I have to log back in again and do it all again.

Is there a way that it can run all of the time as a service and maybe send a telnet command from the Duet to say,
I am about to print, get ready!!
i.e. M118 P4 S"Print Starting"

Which in turn enables DuetLapse with the users setting.

Just a thought

Regards,
Paul.

[Danal]

I will think about a way to do this... while minimally banging on the printer between prints.

[PaulHew]

Had a Malloc error, used all default settings.

Capturing frame   522 at X10.00 Y280.00 Z120.00

Now making 523 frames into a video at 10 frames per second.
This can take a while...
x264 [error]: malloc of size 25549312 failed
Video encoding failed
Killed
Video processing complete.
Video file is in home directory, named ~/DuetLapse0413200101.mp4

Was looking forward to this TimeLapse

[Danal]

As long as you have NOT started the overall script again, or rebooted, the images are still there and you can try to make the video over and over.

The actual command issued is:

ffmpeg -r 10 -i /tmp/DuetLapse/IMG%08d.jpeg -vcodec libx264 -y -v 8 ~/DuetLapse0413200101.mp4

You could try other ffmpeg options (I am not an expert), try making two videos out of half the images, and stitch the vids together later, etc, etc.

To be clear, the images are in /tmp and are named

IMG00000001.jpeg
IMG00000002.jpeg

Etc.

Awesome program. One issue I've always had is that my wifi and or duet do not like each other and disconnect constantly, but will always reconnect eventually. Is it possible to automatically 'skip' a frame if there is no connection to the printer at that time and not to throw an error?

Also would be nice if it looked at the file name it was printing and made subfolders with the name of the print

Yes, I will add some error handling to the key spots.

Also would be nice if it looked at the file name it was printing and made subfolders with the name of the print

Hey, great idea!

[Baenwort]

@Danal does DuetLapse require RRF3 or a certain version or above of DWC?

I'm interested in trying it.by I don't know.what you mean by the step that says to place the DuetLapseAPI.Ph in the python libpath? Is it enough to place all the .py files in one directory?

[Danal]

• Supports Duet printers running V2, V3 standalone and V3 +Pi.
• Printer must be reachable via the network.

I'm interested in trying it.by I don't know.what you mean by the step that says to place the DuetLapseAPI.Ph in the python libpath? Is it enough to place all the .py files in one directory?

That step actually says: Copy included module https://github.com/DanalEstes/DuetWebAPI/blob/master/DuetWebAPI.py to the same directory, or to anywhere in python's libpath.

Thanks for the questions, I will do a bit of readme editing to make all above more clear.

If it helps with putting caption overlays on your output movie files I have been playing with ffmpeg in the last few days. The command I am using is

ffmpeg -r 10 -i ./IMG%06d.jpg -vcodec libx264 -crf 15 -s 800x600 -pix_fmt yuv420p -y -v warning -vf drawtext="fontfile=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSerif.ttf: text='Text to put on screen':fontsize=40:fontcolor=yellow:box=1:boxborderw=5:boxcolor=black@0.5:x=10:y=10" movie.mp4

This will give you a caption in the top-left with a semi-transparent black box around

What people are requesting changes as the frames flow. Things like Z height, etc. I believe those overlays need to be part of the stills.

That's true, if they need to reflect things changing as the print progresses.

I'm writing a similar program to yours. I use motioneye to generate my original images from a picam which is then displayed in the DWC Webcam view (or via a browser window).
Motioneye uses motion which has a http api available.

e.g. To take snapshots

http://localhost:7999/1/action/snapshot

will cause motion to take a snapshot from Camera 1 and place it in

/var/lib/motioneye/Camera1

I'm picking them up from there, creating a movie when the print is complete (ffmpeg) and uploading it to my NAS server.

I had thought of doing something like this for a while but you have inspired me to get it done. I admit I have "borrowed" a few ideas from your program.
Also I'm using Java as it's what I'm more comfortable with. I like Netbeans as an IDE as it's perfect for Java development.

The great architectural principle of "reuse". Cool!

[Adrian52]

Thanks very much for this. I got the program working, but the pause doesn't seem to work properly for me. I get multiple pauses on a single layer. My bed. g moves the head out of the way, so I don't have a movehead command. Using duet2 WiFi, delta, rrf3. 01rc9
