4k webcam configuration

Hi ,

Is anybody already gets the 4k functionnality working with jisti ?
What is the optimal or best congifuration to use ?

I was expecting buying the [BRIO ULTRA HD PRO WEBCAM]

With my actual webcam in 720p I’m tryning to skip the VP8 codec and force the H264 by default.
But it’s result with a poor quality ( ie reslution blocked at 360p despite the resolution is force to 720p with min, max forced to 720 p )

Any suggestion or comments ?

Thanks by advance.

Can I join your group call can you send me the code of your meeting,

Before I buy the 4k webcam, I will make sure of the capabilities.
At the moment, the connection seems reduced and the HD cameras back to 640x360.
I can not find a way to force to keep the resolution and prevent resolution changes.

From what I’ve experienced, every time you restart the docker container to apply the new res settings, it reverts the config.js file back to the original format.

Have you found a solution to this yet?
