https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org/... oh, so many details about error management! from 2013.. ==== To summarize the process: Use x264 through ffmpeg or directly to convert the video to H.264 per the recommendations on www.x264bluray.com. Add the -fps flag if you need it. Unless you have a REALLY fast machine or an eternity to wait, use the slow preset instead of veryslow. Extract the audio, I used ffmpeg to extract the existing AC3 audio. Use tsMuxeR to create the proper blu-ray folder structure and mux'ed stream (unfortunately not FOSS, but free) Use ImgBurn under WINE to create the image for burning, which supports UDF 2.50 for blu-ray (and 2.60, but that's not needed). === so for now tsmuxer IS free, but imgburn not. imgburn might require setting windows version in Wine to winxp https://www.imgburn.com/ in theory new mkudffs can be used for making udf image, and then.. try udfclient (cli tool from netbsd) to put files into it (should be in debian/ubuntu) ? https://openports.pl/path/sysutils/udfclient === udfclient interactive commands ------------------------------ These are ftp-like, with some differences. Use the 'help' command at the "UDF>" prompt to display a summary. Of particular value is a 'get' or 'put' of a directory. This will copy the entire structure in or out of the filesystem. === https://github.com/pali/udftools/issues/20 https://superuser.com/questions/1552763/using-udfutils-to-create-a-data-bd-r... note, some of those links contradict each other on (un) ability of udfcliet to put files/dirs into udf 2.5 formatted image... Only test will tell.. (afterwards usual linux kernel driver should show files in r/o mode) nerolinux is also non-free (and from 2012) https://medium.com/@justdan96/using-nerocmd-in-ubuntu-19-10-627c5b157fed http://home.thomas.pp.ua/soft/linux/Nero%20Linux%204.0.0.0%20x86_x64/ (not tested)
