I have the same issue on macOS Catalina 10.15.6 (19G2021). Cannot use Capture object in any way.

I have resolved the issue following the steps described by user easyTarget200 https://github.com/processing/processing-video/issues/134#issuecomment-550359384

After following the steps the sketch runs but only using the processing command line tool.

So if i run processing-java --sketch=/Users/username/Documents/Processing/libraries/video/examples/Capture/GettingStartedCapture --run the camera finally initializes correctly but not when running the sketch from Processing directly.

What is this bug? @sam959 clearly you are reporting an issue triggered when attempting to use a Capture object - how did you get to the conclusion that it was the same issue that @IsraelSuen is reporting? I can't see anything in the description of this issue about what the user was trying to do when a crash occurred. The title is "Mac video library bug exists". That's maximally vague. Does anyone know what problem is being described? I'd love to help.

@christo Everybody would like to help with this issue, it is discussed here too: https://discourse.processing.org/t/did-macos-catalina-or-something-break-the-video-library/14699 Might be the same therefore the link I provided in the first comment could be handy. Otherwise we'll wait for more info about the issue from @IsraelSuen! Cheers 👍

Hey @sam959, thanks for your reply. Yes I've heard about the problems people are having with Capture on MacOS Catalina. That bug seems to be tracked many times (although I can't be sure they are all identical) and a brief search shows at least these: #134 #144 #142 #160
