Hi thanks for your instructions!

I also added

```auto
<key>NSCameraUsageDescription</key>
<string>APPNAME requires access to your phone’s camera.</string>

```

in Processing.app/Contents/Info.plist

console output

> Processing video library using GStreamer 1.16.0  
> Available cameras:  
> [0] “FaceTime HD Camera (Built-in)”

So my camera is getting detected. If I execute cam.start() - the light of my camera shortly turns on and off.

I never get any image from the camera → black screen

Any ideas?
