Description
We pass a frame in yuv420p format to libwebp, which then converts it to RGB format. This conversion affects the final image's colors significantly as well as inducing loss of detail. JPEG is not affected, however. From testing, using an RGB format produces a much better image for WebP and looks nearly the same for JPEG.
