Comparing multiple videos -

is there (fast) way compare different videos files, in order find identical sequences, without comparing 2 videos frame frame?

or build-a-hash-of-each-frame-and-compare-it-with-other-hashs-way possible solution?

the fisrt step compare metadata. if aspect ratio , length of video different, there no need run heavy process conclude videos different.

then, may build kind of hash existing, rapid functions ( in ffmpeg guess) think of comparing scene-change timestamps. (result "scene change detection algorithm"

you can process each file, until difference > epsilon . have define , compute 'difference' (delta in change number ? in timestamps delay ?...) , epsilon...

my answer not clear, 1 way can think of. yet, hope helps...
