Hi! With Marton's patches from git clone -b mpegts https://github.com/cus/ffmpeg/ and CinGG compiled with ffmpg.git I _nearly_ got some rendering. But option files still needed some modification For example I was running into x264 errors. cin Cinelerra Infinity - built: Nov 14 2019 14:17:05 git://git.cinelerra-gg.org/goodguy/cinelerra.git (c) 2006-2019 Heroine Virtual Ltd. by Adam Williams (c) 2007-2019 cin5 derivative by W.P.

"vbv-maxrate Maximum allowed bitrate. Depend of destination media, for normal BD Media, maximum settings is allowed (40000), while for DVD Media (eg BD-5 or BD-9) there is no maximum per Blu-Ray specification, but is strongly recommended that use less or equal to 15000, since DVD reading is slower."
