#8544: LUTRGB inaccurate, affects other colors -------------------------------------+---------------------------------- Reporter: chris319 | Owner: Type: defect | Status: new Priority: important | Component: ffmpeg Version: unspecified | Resolution: Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+---------------------------------- Comment (by pdr0): What is "White.mp4" ? What are the YUV values ? You're converting to YUV inbetween, possibly incorrectly, that's not lutrgb's fault You should be measuring the direct RGB output of lutrgb filter (eg. with a bmp), against direct input of a known RGB values e.g. 255,255,255. lutrgb , the filter itself, works correctly ffmpeg -i 255,255,255.bmp -vf lutrgb='r=clip(val,47,194)' out.bmp Result RGB 194,255,255 -- Ticket URL: <https://trac.ffmpeg.org/ticket/8544#comment:1> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
