UVC Server - can't change the resolution

[marian]

Hi, I use an uvc camera which supports several resolution up to 3840 x 2160 @ 30fps.

Using uvc-server whit default resolution is working just fine, but when I try to change the default resolution doesn't work anymore (I tried different resolutions, frame rates ...), as can see in the screen below:

Here is the voxl-version I use:

Can you please advice how to proceed?

@marian Can you follow the guide here: https://docs.modalai.com/voxl-uvc-server/#helpful-tips? Please post the output from those commands so we can see what camera you have and what it supports.

@Eric-Katzfey Sorry for bothering you, I finally found the problem, the frame rate is very low when choosing better resolution than 640x480. Changing the frame rate accordingly it is working fine.

Thanks for your support.

@marian Oh yes, thanks for letting us know. When you are using raw frames over USB 2.0 you have to go to a much lower frame rate or else there isn't enough bandwidth to transfer them.
