I found this screenshot which shows that you can add a cover image to an mkv file in a way that it is displayed as the icon of the file in the Windows explorer using Shark007
+icaros
.
But these tools are messing with the system in a really bad way. A lot of people are having problems with it and I too very much regret that I've installed it. I'm really glad I got my Windows to boot again...
Anyway, how could I programmatically add a cover image to an mkv file?
And would I need to change something in the registry to make Windows display them?
I'm not neccessarely looking for code, I'm more looking for something like the format the cover needs to have and the byte at which I have to inject/insert/attach the image file and maybe a registry entry that would cause the tagged images to be displayed etc.
You can use the FFmpeg multimedia framework to attach an image as MKV
metadata. More Windows builds can be found at Zeranoe.
Example CLI usage:
ffmpeg -i input.mkv -c copy -attach image.jpg -metadata:s:t \
mimetype=image/jpeg output.mkv
-c copy
copy all streams in the source file without re-encoding-attach image.jpg
attach a JPEG image-metadata:s:t mimetype=image/jpeg
set the attachement MIME typeOn *nix the same can be accomplished with MKVToolNix.
