DuetLapse3
-
Feature suggestion: add an option to create a symbolic link that always points to the second-most-recent photo for a currently-running timelapse. For example, the current directory for captured images on one of my printers is: /mnt/remote/KosselXT/duet/21439_CFFFP_Riser_191x25_links
An option to have a symbolic link at /mnt/remote/KosselXT/current.jpg that always points to the second-most-recent image would allow us to add it to the DWC interface as a webcam image by serving that file over http. The symbolic link would have to be updated every frame. The reason I'm specifically referring to the second-most-recent image is that sometimes the current image isn't complete yet when DWC tries to display it. Pointing the link to the second-most-recent image would always display a complete image, at the expense of being a few seconds behind. -

Iβve found that itβs important / helpful to prove the command independently of systemctl first. What do you get from the log file when you use the same command with -verbose ?
-
@goremanx
Not sure what this has to do with DWC and Duet Lapse3. Why not just point DWC to the same camera source as DuetLapse3? -
@stuartofmt Because DWC's "webcam" feature only supports a url pointing to a specific image over http. I used to generate that image with my pi camera, but now the camera is monopolized by the timelapse. Since the image I want to see has already been taken for the timelapse, it seems like a good way to kill two birds with one stone. That image could also be used to show the most recent frame on the timelapse status page.

What software are you using to serve up the images from the pi camera ? If its raspistill - yes, it (and some others) only accept a single connection?
Here is what I use - simple and effective: I often have multiple DuetLapse3's, a separate browser and DWC (be sure to enable webcam image in an iframe) - all connected to the one instance.
line 75 can be edited for the port number, line 70 for rotation.

@johnocfii said in DuetLapse3:
referer = self.headers['Host'] split_referer = referer.split(":", 1)What this is saying is that the request (from the browser) did not contain a well formed header url (what you would normally see in the first part of the address bar) E.g. localhost:port ..... or ipaddress:port ......
Just why I cannot say.Does it generally work ? Was this a transient ? Is it repeatable in any way ?
I'm about to release a small upgrade and might be able to include some checks / mitigation but don't really know what to do if it fails. Any verbose logs or other info would be especially helpful.
-
@stuartofmt Greetings!
I added -verbose and ran from the command line with no issues. So -- I added verbose into the systemctl script, and it ALSO ran without issue. Then I removed the -verbose tag, and things continued to work.
I blame it on the Moderna vaccine I received the other day.
I have no idea what my issue was... Sorry if I caused you to rack your brain.

Some fairly small but useful additions. Personally - I am tending to use -keepfiles in all instances and using startDuetLapse3 to manually tidy up etc. as I need to.
###Version 3.4.2###
Changes to DuetLapse3
-[1] Added a new options: -keepfiles to prevent file deletion on startup and shutdown.
-[2] Terminate (from the UI) now offers two options: Graceful and Forces. Graceful is the same as in prior versions. Forced does a quick shutdown with no image capture.
-[3] Added an optional argument (-maxffmpeg) that limits the number of concurrent ffmpeg instances. Ffmpeg can fail due to lack of resources - the default is 2 instances.
Note that this only applies to video creation. Image capture, because it is transient, is not limited.Changes to startDuetLapse3
[1] Can now delete empty directories (provided they are not in use). This allows a complete cleanup of the directory tree.
[2] Added file function to create a Video on directories containing jpeg files (provided they are not in use).
[3] Added an optional argument (-maxffmpeg) that limits the number of concurrent ffmpeg instances. Ffmpgeg can fail due to lack of resources - the default is 2 instances.
Note that this only applies to video creation. -
Hi all,
I have installed DuetLapse3 and verified it's running well (it does).
But with me being a newbie at all Linux-things, I'm not sure about some basic things...- What would be the best way to have DuetLapse3 start at boot? I have added this line to rc.local but not sure if it would work:
/home/pi/duetlapse/duetlapse.sh start &If I run "duetlapse.sh start" it works.
- Is it ok if I keep DuetLapse3 running at all times? Would it start capturing automatically, every time I start a print, and stop capturing when print is finished? I have DWC, uStreamer and DuetLapse3 on the same RPi (RPi 4 4 GB).
3 (LE). One more thing. I have noticed that DuetLapse3 terminates itself after a print is finished and a video is created. I would like to automate video capture and not worry about whether DuetLapse3 is started or not when I start a job. This means I'm fine with DuetLapse3 being active all the time and capturing all my prints. Question is, how would I go about automating that? Keep DuetLapse3 idle and waiting all the time, start capturing when print starts, save video and go back to idle, waiting for a new job to start.
-
Greetings -- My last couple of prints, I noticed that I wasn't getting my "extratime". The log told me that my version of ffmpeg didn't support it, even though it was the version I built locally on my Pi last December.

Any ideas, or places to check?

I'm tied up all day - but will give you a considered answer later today (if I can ) but more likely tomorrow. The good news is that its all possible and pretty straightforward BUT there are options

Do you mind trying 3.4.3. Looks like it was a silly mistake - but I do not have time to rigorously test at the moment.

@stuartofmt sure - I'll try that soon.

No rush, I am still tuning and polishing a lot of things with my printer. Take your time -
Hi - I think the simplest approach (for now) is to run DuetLapse3.py using the linux systemctl capability.
I updated the instructions here:
https://github.com/stuartofmt/DuetLapse3/blob/main/systemctl setup.md
and added a sample unit file (.service extension) here:
https://github.com/stuartofmt/DuetLapse3/blob/main/DuetLapse3.serviceNote that you want to make sure the options you have set are perfected by running DuetLapse3 from the command console, before you replicate these in the unit file.
Essentially - using this approach, DuetLapse3 will terminate normally at the end of each print job and then restart.
In particular - you likely (definitely) want to have -detect layer set. Otherwise - on restart of DuetLapse3, even if there is no print job running, it may start capturing images the entire time
-
Thank you for your answer.
