This is the first release of prebuild binaries made with pyinstaller. For them to function properly the VLC media player has to be installed. To launch the GUI just run ./catvibes --gui or .\catvibes.exe --gui. The windows executables ship with ffmpeg (from https://www.gyan.dev/ffmpeg/builds/ffmpeg-git-full.7z) as it is quite difficult to install on windows, but on linux ffmpeg has to be installed already.
