Custom thumbnails for videos not displaying

Post by MontanaFur »

I use mediamonkey to embed cover art into mp4 files. In Windows file explorer these display as the thumbnail by default. In Xnview Mp however only 2 of my 50+ videos display this thumbnail correctly. Instead, it snatches one from a percentage of the video etc. How can I display my custom ones?

Apologies but all of the mp4 files would be too large to share. Is there some other way I can help?

I also had found this problem! ...and since it still exists in the current version, I am chiming in on this bug report.

I could send you an example video if you like;... or you could just make your own:

Code: Select all

fmpeg.exe -hide_banner -i video.mp4 -i thumbnail.jpg -map 0 -map 1 -c copy -disposition:v:1 attached_pic videoWithThumbnai.mp4
Any video with an embedded thumbnail seems to fail to show the embedded version.
As MontanaFur said in the original post, Windows Explorer correctly displays the embedded thumbs.

P.S.: when using the INFO pane > Properties tab: I see sections for: FILE, IMAGE, VIDEO, AUDIO
I had always thought that the IMAGE section was the embedded thumbnail.
Since it is not; what is it for? (if anything)

thanks,
Kevin
