Video -> Thumbnail multi pictures preview

[rs232]

I have brought up this feature request already when I was a Plex user and as usual it was just ignored.
I still think this is a great feature to have, so I'm bringing it up to the Jellyfin community.

Without going through the generating, saving, etc, IMO this could even be displayed on the fly when the details of the movie is opened.

AI gave some interesting idea (requiring ImageMagick) on how to achieve this:

This extracts one frame every 15 minutes (900 seconds) and produce images named thumb001.png, thumb002.png, etc.

Code:

ffmpeg -i input_video.mp4 -vf "select='not(mod(n\,45000))'" -vsync vfr thumb%03d.png

After extracting the frames, use the montage command from ImageMagick to create a single image containing all the thumbnails:

Code:

montage thumb*.png -tile 4x4 -geometry +2+2 output_thumbnail.jpg

I hope this would be considered.
Thanks

Jellyfin already KIND OF does this with chapter image extraction.
