Hello, I would like to disable the deblocking filter for x265. The manual shows: --no-sao But I get the message: Unrecognized option '-no-sao' The code I use: /usr/local/Cellar/ffmpeg/3.4.2/bin/ffmpeg -stats -loglevel 24 -i surce.mkv -map 0:a -map 0:v:0 -c:v libx265 -crf 20 -c:s copy -c:a copy --no-sao -ss 5000 -t 5 destination.mp4 Kind regards Daniel
