Author of PySceneDetect here: Thank you all for the thought-provoking discussions, and the attention you've given my side project. There are some specific cases where PySceneDetect achieves great accuracy (like fast cuts or fades), and some where it's currently not so good at (like sudden flashes or large obstructions). That being said I do want to track these things and come up with solutions to improve the robustness of the content detection algorithm over time.

I'm most open to any feedback or feature requests/ideas/suggestions; feel free to checkout the issue tracker on Github, or create a new entry:

https://github.com/Breakthrough/PySceneDetect/issues

Some ideas being considered/researched for future releases:

- looking at changes to image histograms

- using edge detection to improve robustness

- camera flash / foreground object suppression

- automatic threshold detection using statistical methods (currently is just a heuristic)

So this is likely beyond the scope of your project, but I've always thought a really good project would be a website to host scene indexes for movies and TV.

Eg. Let's say that you wanted to watch a prerecorded football game or baseball game without all the commercials, timeouts, commentators talking about the fans, etc.

Or... Let's say that you wanted to re-cut a movie in a certain way, by re-ordering the scenes, you could just generate a new scene data file and let the encoder/player use that.

This is still relevant I think :) What you mentioned is very similar to an edit decision list (EDL [1]), of which I only learned recently. I had a feature request [2] to support EDL as an ouptut format, and upon further investigation, it seems like the format is very similar to what you're talking about. The Wikipedia page also indicates that VLC supports xspf files, but I haven't done much research into that yet ("XML Shareable Playlist Format").
