What happened instead?

Did the same happen when running OctoPrint in safe mode?

Yes

Version of OctoPi

Fully updated/upgraded nightly build for RPi4, 0.17.0

Printer model & used firmware incl. version

Prusa MK3S

Screenshot(s)/video(s) showing the problem:

I have read the FAQ.

It's probably due to libav-tools getting dropped from Buster, I'll check if timelapse gets created with ffmpeg instead of avconv.

edit: Works with ffmpeg, so I guess this is jsut a matter of changing the configuration of the pre-built image.

[guysoft]

Ok, can you write in detail what packages you installed and what configuration you changed for it to work.

Also cc @foosel this means timelapse is broken in nightly

[JirkaChadima]

Sure. I tried to install ffmpeg package, but it turns out it's already installed in the factory octopi image. So all I did in the end was to change the configuration in OctoPrint's UI from /usr/bin/avconv to /usr/bin/ffmpeg

Octopi is setting the path here and I was not able to find any mention of avconv in octoprint's master branch. I think the fix for buster would be to change the path in octopi's build config.

[guysoft]

This should be fixed in nightly, anyone can confirm?

[JirkaChadima]

The one from October 13 on this page? I can confirm, but in a few days time, I'm a little busy ATM.

[guysoft]

@JirkaChadima Yes that should include the fix, confirm when you can :)

I'm still seeing avconv preconfigured. So I guess the next nightly after today's PR merge will contain the fix?

[guysoft]

It was merged 2 hours ago. Next nightly.

[guysoft]

Yes
