Set MP4 thumbnail

Question

With AtomicParsley, you can set the thumbnail that will be displayed when you look at the file in a file explorer. Example commands

$ atomicparsley infile.mp4 --artwork infile.png

$ atomicparsley infile.mp4 -t
Atom "covr" contains: 1 piece of artwork

I notice that the artwork shows up as a stream with FFmpeg

So, is it possible to mux in thumbnail artwork using FFmpeg?

Answer 1

Try to use ffmpeg -disposition option along with -map.

ffmpeg -i video.mp4 -i image.png -map 0 -map 1 -c copy -c:v:1 png \
-disposition:v:1 attached_pic out.mp4

More information can be found in ffmpeg documentation:

• -map option
• ffmpeg main options

Also, please note, it's not guaranteed that the image you use will be showed in a video preview or as a file tumbanail, because different software programs may not use embedded thumbnails at all.

Answer 2

This can be done with the TagEditor project. To add:

tageditor -s cover=y.jpg --max-padding 125000 -f z.mp4

To remove:

tageditor -s cover= --max-padding 125000 -f z.mp4

Answer 3

Yes you can, but support depends on your container format; mp4 will work but others may not.

ffmpeg -i INPUT.mp4 -i IMAGE.png -acodec copy -vcodec copy -map 0 -map 1:0 OUTPUT.mp4
