I've tried to upload an animated webp file, and Danbooru said it was not supported. (Or I messed it up.)
Posted under Bugs & Features
In the meantime does anyone have tools to losslessly convert animated webp into a gif/apng/else? (extract the exact images, and build up a something else in the other format)
post #7563338 [direct link] needs to be converted correctly and replaced
As far as I understand, the format itself does not contain sufficient data for full decompression. Due to this, official Google utilities have limited functionality.
The closest third party solution is from ffmpeg, which has many uses. https://patchwork.ffmpeg.org/project/ffmpeg/patch/20230706112731.35895-4-thilo.borgmann@mail.de/#78839 https://trac.ffmpeg.org/ticket/4907 I haven’t tested it, but according to the description it’s still in development.
I think the lack of utilities also limits the site's ability to provide support for working with the format in various aspects. But I'm not a developer to comment on this.
