Thanks for giving PySceneDetect a try. Can you share what you're using as the command line arguments?

For detecting fades-to-black, you want to make sure that you're using the detect-threshold command (not detect-content). For example:

    scenedetect -i somevideo.mp4 detect-threshold -t 12 list-scenes

Where -t specifies the threshold to use (the default being a value of 12). Full documentation for the detect-threshold command:
