Hello, in attach a patch to add test for lossy decoding of webp.
Compare with dwebp tool, the result of ffmpeg in yuv is exactly the same than the official decoder. (trouble report in my previous email, concern rgb/rgba output (because the filtering yuv420 -> yuv444 of libwebp is not implemented). Samples can be found here : https://we.tl/QKy6uyDJpx and need to be put in ./fate-suite/webp/ The patch need to be apply after the previous one (call : 0001-fate-webp-add-test-for-webp-lossless-decoding-rgb-an.patch") Martin
