Octolapse with Android Camera

[jccf07]

If this is a feature request describe it here

Is it possible to run a script, but not check if it is correct?
I think it would be very useful, to a lot of people, to be able to use an old smartphone to take photos, I currently have an HTC ONE 10 with a great camera, in a drawer. I want to use it to take photos with optolapse, but with my own script. This script will turn on the mobile, take a photo, send it to the PC and turn off the mobile screen.
Later, through other programs, it will be possible to mount a timelapse.

My script it is very simple, an it is runing ok:

!/bin/bash

adb shell input keyevent KEYCODE_WAKEUP
adb shell am start -a android.media.action.STILL_IMAGE_CAMERA
adb shell "input keyevent KEYCODE_FOCUS"
sleep 2
adb shell "input keyevent KEYCODE_CAMERA"
adb pull /mnt/sdcard/DCIM/100MEDIA /home/jose/Escritorio
adb shell input keyevent KEYCODE_SLEEP
exit

What were you doing when the problem occurred

Currently I have tried to use the method for a DSLR camera, with gphoto2, but it is not possible to take photos. (capture is not supported)
I get the following:
jose @ ServerHA: ~ $ gphoto2 --auto-detect

What should have happened?

Octolapse start working, and execute script in every layer without check script

What happened instead?

Octolapse get an error, and print start fails

The check script should only complain if the script doesn't return success or times out. Looks like it timed out in your case. I will take a closer look ASAP to see if I missed anything.

Also, thank you for filling out the issue template so well! Once I get more time to examine this I'll probably have the info I need to solve this.

Thank you very much for your excellent work and your contribution to the community, it is amazing. I read a lot issues before post mine.

Please, if you need help with testing, I am available to help

PS: Right now I'm using the "action command" plugin to send the OCTO1 command (which runs my script) after each layer (setting Cura and Simplify to do this job).

I'm going to try to make the Octolapse´s job manually for the moment. Can you share the gcode that Octolapse performs after each layer? I'm not sure if it just moves the extruder in XYZ or does a retract too

Thanks!

[FormerLurker]

Octolapse can send gcodes after stabilization too, fyi. Add a new camera, and select the 'script camera' option. Not sure if the action commands plugin will be able to intercept the command, but it is worth a shot!

[FormerLurker]

Oh, when I have time i will send a description of the gcodes octolapse generates. It depends a lot on the settings, but it can retract, lift, travel to the destination, wait for moves to finish (m400), take a snapshot, return, delift and deretract.

Thanks!! it is working now, I use a blank script, I just have this write inside:

!/bin/bash

exit 0

And then I use fyi, "After Snapshot Gcode" to write "OCTO1" (to run my own script with Acction Command Plugin). I attach screencapture

[FormerLurker]

Excellent! Now I know that can work :) I will still try to figure out why the regular script camera isn't working for this (I think it should...).

Also, I recommend you set your Snapshot Delay to 0MS. That will shave a bit of time off of your print and marginally improve quality. If you notice shaky looking frames you can always turn it back up again.

Happy printing :)

[jccf07]

Thanks again! I´m goint to set Delay to 0MS
only one more thing,
Is it possible that octolapse shows the last snapshot taken by my script? could I indicate a route and have octolapse show it?

[FormerLurker]

You'll need to copy it down to your pi. This will be difficult since the gcode itself doesn't contain the file name you need to use. This is normally passed into the camera script as a parameter. However, it could be manually determined by exporting your camera profile. Look for the GUID value in the exported profile and put the image in the following location (assuming you are using OctoPi here as well as the default directories in the Octolapse main settings):

/home/pi/.octoprint/data/octolapse/tmp/octolapse_snapshots_tmp/latest_thumb_{camera_guid_here}.jpeg

The image should be scaled to 500px wide if possible. Not sure what will happen if you don't do this :) I believe it will be squished while maintaining the aspect ratio, but I am not 100% certain.

Thanks, I"ll try tomorrow and I write feedback
