Comment (by Andrew-R):
I think I should add to this bug reference to Cinelerra-GG (linux-only
non-linear video editor). It uses ffmpeg (4.2+ few patches), and can use
ffmpeg.git . I was looking at failing patch inside source tree and
apparently exactly patch failing to apply should add more accurate Blu-Ray
muxing.
https://git.cinelerra-
gg.org/git/?p=goodguy/cinelerra.git;a=tree;f=cinelerra-5.1/thirdparty/src;h=5bfd7e92d793c3100827dd216bb81fb6f56eff54;hb=HEAD
see ffmpeg-4.2.patch2 and ffmpeg.git.patch2 . Well, git one fails to apply
after recent (aug/sept 2019) round of fixes in mpegts muxer. Without it
some udf file is generated, I can even play/seek it with mplayer, but I'm
sure real player will choke on it - some errors detected on seeking.
Compilation (of CinGG) relatively simple, I run it on Slackware 32-bit
often. You can use pre-build packages from https://www.cinelerra-
gg.org/downloads/#packages but obviously for your own changes you want
source.
There is item in main menu called Create BD, it will prompt you to choose
type (size, framerate, interlacing) of project, and some empty space to
run encoding and muxing. You don't need all 25 or 50 Gb - just load small
(2 min for example) file, change project settings to something more like
Blu-Ray spec/profile, and fire it. Note: Cinelerra will quit with few
console messages after muxing step is finished, this is normal. But run it
from terminal {xterm, konsole ..} so those messages will be seen, or any
errors, too.
There are option files controlling muxing/encoding, you can see them
online https://git.cinelerra-
gg.org/git/?p=goodguy/cinelerra.git;a=tree;f=cinelerra-5.1/ffmpeg;h=3d53bdac732998d97a25abfe904ce97bea8c5bec;hb=HEAD
or in your Cinelerra-GG installation (for me they live in /usr/share/cin,
but this is configurable).
