Just to make for others easier in the future, managed to have a video input from a webcam into Gem on Mac OS X 10.14 with the VLC plugin, which I admire very much :)

Opened vlc first and added a Capture Device, which opened immediately the webcam with a tytle of the window on the top: qtcapture://0x14100000043e3009.
So sent a message to pix_vlc: device qtcapture://0x14100000043e3009 and tadam there is the live input from the webcam.

What is even better that I can use the same stream twice, once to VLC and simultaneously into Pd as well.


Thanks for all the info you gave,  that is why I love this community!

Best,
Popesz
