Aspect ratio for camera

[MartiMan79]

Hi all,

Is there a possibility to set the aspect ratio of the camera livestream?
If I change anything in the advanced settings the stream stops working...

I tried to set the resolution: "scale=1280:960",
Also tried to use setdar in various ways, all without success.

What am I doing wrong here?

Thanks in advance.

Strangely it started working from the moment I put the adapter in debug mode 😂
