Hi @Dakanox from what I see on the logs it could be an issue with the capture resolution, have you tried with different values? The same as the one for preview for example (640.0, 480.0).

@werdeil Hi, thanks for responding.

The lowest resolution my camera goes to is 1600x1600 using 1:1.

I have adjusted the config file to match that resolution as well as 1984x1984 but the same error appears unfortunately.

Not sure a 1:1 resolution is a good way to test, does the preview work with this kind of resolution?

As stated from the log I can see that the preview is done with the following resolution: (640.0, 480.0), could you try to capture with this one?

And if possible can you run the pibooth-diag command and paste the result please? It can help.
