CLI: Numeric way to compare two video files
I'm looking for a method that reliably gives me a "mathematical distance" of two videos from one another. Similar to how the Levenshtein distance can be used to get the distance from a string to another.
What I have
For example, I have a lot of videos that may only vary in codec (duplicates). The file formats range from webm, mp4, flv, mkv to avi. Comparing those videos with sha256sum does of course not work, similar to certain frames of the video which vary by slight changes in artifacts. One idea so far is to use ffmpeg to get pictures for every frame each x seconds, use compare from ImageMagic to get a numerical distance and use awk to calculate the average of the total value over the amount of images. This has a few disadvantages that I would like to get rid of:
it only works for images
I have to manually tweak the threshold of the
comparemetric until I'm technically below that of artifacts to be confident enough to allow automatic deletionsI have to manually review every video with it's potential duplicates to know what the differences are (from start to finish)
