Hello Raphaël,
Thank you very much for the tip, but unfortunately I have to stick with version 4.3 of Flatpak. The Snap version still doesn’t work, especially when we need to install extra libraries. The snap version of processing-video is a nightmare to get working. And since I use Processing with beginner students, it’s not feasible to go through the whole process of adjustments and environment configurations necessary to make the snap version work. I’m very happy to hear that a flatpak version is planned!!! I look forward to it. Once again… thank you very much for everyone’s effort and dedication… Processing really is a great project that we love!!!
