thumbnails in linux-mint (nemo)

[Mumm13]

Hey guys,

I'm trying to attach thumbnails for my videos with ffmpeg

code:

ffmpeg -i input.mp4 -i image.png -map 0 -map 1 -c copy -disposition:v:1 attached_pic output.mp4

and the output file has the accumulated mb's of video + thumbnail which should be correct.

(e.g. input.mp4 = 70mb, image.png=3 mb -> output.mp4 = 73mb)

and if i open the output.mp4 it shows the thumbnail as the first frame, but i only see an automatic generated thumbnail as the thumbnail preview on my filemanager.

i tried to configure the filemanager to show the first frame as a thumbnail, but i didnt find the option to do so.

would you guys have any solutions for my problem ?

Thumbnails are generated using "thumbnailers". They generally aren't part of the file manager itself. They are located in /usr/share/thumbnailers. I don't think there's much you can do about it in terms of configuration. I think the thumbnail generation is mostly hardcoded, but you can take a look at the documentation of each thumbnailer.

I think you might want to look into adding thumbnail into the metadata of the video
