It is most likely an issue with the version of gstreamer, the “old” library does not work with gstreamer-1.0+ which is what recent linux and presumably newer Mac have. There is [`beta` version of video library](https://github.com/processing/processing-video/releases/tag/r6-v2.0-beta4) available that supports gstreamer-1.0+, however you will need to modify your sketches to get them to work, might well work with test capture sketch though. Basically you have to name the Camera you are using. See [Video library to use new GStreamer bindings](https://discourse.processing.org/t/video-library-to-use-new-gstreamer-bindings/2223/2) and my JRubyArt example [https://github.com/ruby-processing/JRubyArt-examples/blob/master/processing\_app/library/video/capture/mirror.rb](https://github.com/ruby-processing/JRubyArt-examples/blob/master/processing_app/library/video/capture/mirror.rb).
