Document Camera problem

Hi there,
I use a HueHD document camera (USB plug & play). The camera works perfectly on my iMac. As soon as I start a jitsi session and access the camera, the image appears reversed. I don’t find any way to edit the camera settings at jitsi !? I look forward to a short message!
Best wishes

noticed the same with some webcams …

but not a problem of jitsi in general (and theres no way to change settings for it, to mirror or whatever)
it seems to be a general problem of webrtc (saw the same effect on many other tools build on webrtc)
… or some camera driver stuff related to it
