Hi all ... Not much to report, just another recompile of CinelerraGG. I made typo in one of my patches, so compilation stopped in x265, but then I fixed it and tried resulted Cinelerra for encoding .. cin Cinelerra Infinity - built: Aug 6 2020 08:57:33 git://git.cinelerra-gg.org/goodguy/cinelerra.git (c) 2006-2019 Heroine Virtual Ltd. by Adam Williams 2007-2020 mods for Cinelerra-GG by W.P.Morrow aka goodguy Cinelerra is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions.

I also tried this new CineformHD encoder in ffmpeg, using attached options file: cat /usr/share/cin/ffmpeg/video/cfhdenc.qt mov cfhd It worked at around 7 fps for 1080p h264 source in RGBA-float project ... Decoding with mplayer was fine if I set CPU to on-demand performance, but just 4x 1.4Ghz of my AMD FX 4300 was not enough for single stream decode. This codec was rumored to be fast for both encode and decode, guess ffmpeg implementation not very fast yet ...
