Can't reproduce. It's not scaling, because it already fits the target size. Could be libwebp. What version is FFmpeg linked against?
Actually, if you are talking about meguca, it's github.com/chai2010/webp that does the WebP encoding. What is the libwebp version on your system?
@bakape, sorry for late answer. libwebp 1.2.0-1 in system github.com/chai2010/webp v1.1.0
