Hello! I tried magicyuv encoding in CinGG, it works with attached option file, and can be viewed in mplayer (compiled with latest ffmpeg git) after I modified .mplayer/codecs.conf cat magicyuv.qt mov magicyuv pix_fmt=yuv444p threads=2 (for some reason first pixel format in encoder's options in CinGG list still not what i tried to set as pix_fmt, so just for being extra safe I set it manually) add this into mplayer's codecs.conf: videocodec ffmagicyuv info "FFmpeg Magicyuv" status working fourcc M8Y4 ;format 0x3459384D driver ffmpeg dll "magicyuv" out YV12,422P,444P,422P10,444P10 After this, mplayer plays this file (24Mb/s for just 1440x900x24bpp_30 fps!) mplayer /dev/shm/magicyuv.ff -vo x11 MPlayer SVN-r38152-5.5.0 (C) 2000-2019 MPlayer Team 224 audio & 466 video codecs Playing /dev/shm/magicyuv.ff. libavformat version 58.33.100 (internal) libavformat file format detected.
