An easy tool to extract slides from presentations ( lectures 😉 )
slide-extractor -p <path> -s <number> -d <number>
-p or --path: Provides the path for the video file ( * required)-s or --skip: Provides the skip seconds for the video.( Captures the video's frames at interval of specified value )-d or --diff: Specifies the difference level between current and previous slide ( a slide is included iff the difference is higher than the specified value)-h or --help: Help Menu
Try adjusting the diff value if you think all slides aren't being captured or too many slides are being captured.
Too Low diff value will make the extractor captures slides even with slight difference.
Too High diff value might make the extractor skip certain slides.
