Andrew, Status update for Bluray - I hate to give up on the rest of the bluray changes. Here is a list of current bluray patches problems from megapile_8. 1) Some concern about current lpcm/bluray checkin with error message of "*unknown bluray stream type pcm_bluray*" on my Fedora 32 laptop. BUT works on Ubuntu 16 and on Fedora 35 laptop (exact same model). I think there is some package that needs to be installed but is not on Fedora 32, but I have no idea what it could possibly be. At any rate, leaving checkin as is since when I create an appimage on the non-working Fedora 32 and move to the working Fedora 35, lpcm works just fine. Going back through a lot of email, I noticed that in January, Terje also got this error message and I believe he uses Leap O/S. 2) When I say "lpcm" works just fine, I only mean that the LG player attached to the TV, shows it is lpcm. I have no idea if it does what it is supposed to do. Not enough knowledge or speakers here. 3) Having verified that I am using the correct bdwrite, on all of the aforementioned computers, get "unknown bluray audio format 0 ch" from line 2469. Something is missing. Did apply 0004-Improve-truehd-decoder-encoder-from-ffmpeg.git.patch and uncommented truehd profile line 865 in bdcreate.C. 4) 0004-Improve-truehd-decoder-encoder-from-ffmpeg.git.patch when applied to the current GIT ffmpeg (which is what will be used in the next build) is out of alignment as seen in the build log below. BUT unless Truehd is working, there is no need for patch-5-8. patch -d ffmpeg* -p1 < src/ffmpeg-4.4.patch_5 Waf: Leaving directory `/mnt0/cinelerra-5.1/thirdparty/serd-0.30.4/build' yes 'build' finished successfully (0.852s) checking for memory.h... patching file libavcodec/mlpenc.c Hunk #1 succeeded at 100 (offset -3 lines).

Hunk #2 succeeded at 2401 with fuzz 1 (offset -6 lines). 5) Also, again I have no idea if "tsmuxer" really does what it is supposed to do even though checked into GIT. When I create a bluray disc, it still plays on my LG so at least it did no harm. Someone else is going to have to verify this because I do not want to install tsmuxer/ninja on this laptop due to the fact that this is where I create the regular AppImage release. 6) 32-bit Debian version 11.0 had a compile error in bdwrite, BUT I have to check that out for sure. That version/computer is a slow build so I keep delaying. Will let you know. 7) OK, so now you can change the interval for chapter, but how does a user do that?
