Processing Video not working with MacOS Catalina (10.15.4)

[leifmarcus]

Hello, i tried to run a sketch with included video Capture, but nothing happens.

What i Tried is to use the r6-v2.0-beta4 release and also updated to the current GStreamer 1.16.2 which is also printed into the Processing console as follows

Processing video library using GStreamer 1.16.2

When I try to run the example sketch AsciiVideo i get the following error:

BaseSrc: [avfvideosrc0] : Device video access permission has just been denied

Seems like the Implementation that is mentioned here is missing. Is there a way of solving the Issue anytime soon? I found that many people seem to have this problem with MacOS Catalina.

Just stumbled on this in general trying to use GStreamer command line on Catalina, so even thought I'm not using processing-video myself, maybe it could help or give some directions.

I was first trying to open streaming video from my webcam and got exactly same denied error from my command:
gst-launch-1.0 -vv avfvideosrc ! videoconvert ! x264enc speed-preset=superfast tune=zerolatency pass=qual ! rtph264pay ! udpsink host=127.0.0.1 port=5050 sync=false

And no dialog for granting permission was show.

But when I just tried to show video in a window, macOS did prompt a dialog and asked if Terminal could be allowed to use camera, I did so, and now the above headless video usage is allowed as well. And whole Terminal app is now allowed to use Camera...

With this command the dialog appeared:
gst-launch-1.0 -vv avfvideosrc ! video/x-raw,width=1280,height=720 ! autovideosink
