Virtual webcam input video device in problems

I tried to use “Snap Camera” as input for videodevin. But it does not work - I just get a black square output.
It acts as a virtual webcam that adds some face recognition AR effects to a source. Snap Camera works without any problems with other software like quicktime, zoom or OBS.
What can I do to make it work with TouchDesigner?
I’m able to receive the virtual webcam stream with OBS and output it to TouchDesigner as NDI Stream. Other Devices like the built in “Facetime HD Camera” work well with videodevin.
Macbook Pro 2016, Mac OS 10.13.6
best regards

Hi - thanks for the report (and the excuse to play with Snap Camera). This is something we’re going to have to fix on our end - we’re taking a look.
