Octopi - Rendering Timelapse failed with returned error code

Camera model Logitech C920

What is the problem? Timelapse fails with no error code mentioned

Example Error: “Rendering of timelapse COLLAPSING_PIRATE_SWORD_small_20200404163307 failed with return code ”

What did you already try to solve it? I have tried updating the camera_usb_options to “-r 1280x720 -f 10” as mentioned in the supported camera section on the octopi wiki.

I researched the octopi.log file and found it mentioning an error related to /usr/bin/avconv. This file does not exist and I imagine it is the root cause of the problem. I do not know how to resolve this issue. I have tried running various apt-get commands. avconv does not have a package and seems to be a part of ffmpeg which is installed and up to date.

Additional information about your setup (OctoPrint version, OctoPi version, …) OctoPrint version : 1.4.0 OctoPi version : 0.17.0 Running on Raspberry pi 3 I recently upgraded to those versions by reflashing my SD card per the instructions provided on the Octopi and Raspberry pi sites. Before upgrading I downloaded a backup of Octopi via the web UI. After upgrading I applied the backup. I believe the previous version I was on was 1.3.12. I could not update through the web UI due to issues related to python. So i opted to update by flashing and restoring a backup.

I can’t access any octopi pi right now so I’m not sure if this could be backup related.

I would check the ffmpeg path in the recording settings. Iirc it should be /usr/bin/ffmpeg

which ffmpeg will show you the path in ssh if that doesn’t work.

And for the avconv part try sudo find / -name avconv

Thank you for the reply. I think you’ve set me on the right path for this.

The path for ffmpeg was correct and existed.

avconv could not be found anywhere on the file system.

Solve I took a closer look at the settings in octoprint and found the WebCam & Timelapse settings had 'Path to FFMPEG' set to '/usr/bin/avconv', which the test button failed because the file did not exist.

I changed ‘Path to FFMPEG’ from ‘/usr/bin/avconv’ to ‘/usr/bin/ffmpeg’. Clicked test and that it returned successful!

I’m going to be running print jobs tomorrow and will test out the timelapse again.

Thank you for your help!

UPDATE: Decided I could just run a short job before hitting the hay. That did it! thanks for the suggestion of looking at the settings for FFMPEG in the web UI.

Thanks It has helped me too

This worked for me as well. Thank you. Once i changed the file path i was able to render the same time-lapse that was previously failing as well so didn’t need to do a new print.
