[boelle]

Try playback of a Blu-Ray with MPC-BE. If this also fails then you may have a "bad" drive that maybe needs a firmware patch.

@boelle...

First up, I've gotten lazy and fall back on Xreveal a lot nowadays because it tends to just work nicely with anything that causes VLC problems. But, since this thread is about "Blu-ray playback with libaacs & libbdplus" we'll stick with that, shall we?

I thought I'd try my copy of The Phantom Menace to see what happened and I got the red screen as well! However, I think my VLC setup has got a bit messed up with me trying various different things so I thought I'd have a bit of clean up to see if I could get it working.

The fact that you're at least getting the red screen error means that you must have got most of the setup correct otherwise you'd not have even got that error message to "work". I wasn't even getting that far and VLC was complaining that "This Blu-ray Disc needs a library for BD+ decoding, and your system does not have it." I had a bit of a poke around and discovered I'd somehow got my vm0 folder inside another vm0 folder... oops! Anyway...

I'd downloaded newer builds of libaacs & libbdplus at some point but not done anything with them so I thought I'd try those instead of the ones from 2020-07-26 that I appear to have been using before. Voila! Both the builds from Roof Tile and hnsteyding seemed to work fine. No more red screen error message.

In the end, I decided to settle with the ones compiled by hnsteyding from May of this year:

TL;DR - Maaaan, I need to be more concise but, basically, try the files from the post I linked to

I came across a post on code.videolan.org about a BD+ - Utilities for generating smaller cached convtabs via in-stream tables.

The first tool (bdplus_diff) and The second utility (mask_regen) will hopefully speed up assisting with open-source BD+ playback.

I'm having trouble compling the program bdplus_diff. Can someone help me?

gcc bdplus_diff.c -o bdplus_diff

Try changing the "fprintf" statements to just "printf" and it should build. Alternatively, change them to be "fprintf(stderr, ...)".

I'm having trouble getting the menus to work for the complete series of Succession on blu-ray. I can either get the title screen to show up but then be unable to click on or play anything from that menu, or I can play without menus and watch only the first episode on discs that usually have 3. I tried fiddling with a few things, but I ended up reverting my setup to the bare bones having the keyfiles, libaacs, libbdplus, libgcrypt, and libgpg error in the aacs folder along with the vlc directory. I set JAVA_HOME to JRE311 with a batch file, and it seems to work for my other discs. My sneaking suspicion is that the discs are too new (released Aug 2024), but I would love to get this working and proven wrong.

I fixed the code so it compiles but i don't know how to use it.

# Compile bdplus_diff and mask_regen on linux

gcc -laacs bdplus_diff.c -o bdplus_diff
gcc -laacs mask_regen.c -o mask_regen

Parse & Diff BD+ discs.

Usage: ./bdplus_diff [disc_root] [cached BD+ table] [obfuscated FUT output] [diff output]
OR: ./bdplus_diff [disc_root] [decrypted & patched disc_root] [obfuscated FUT output] [diff output]

mask_regen: Regenerate BD+ xor masks for smaller convtabs

Requires obfut and diff files produced by bdplus_diff

Usage: ./mask_regen [disc_root] [obfuscated FUT input] [diff input] [convtab output]

All i have to go by it that convtabs are stored in ".config/bdplus/convtab" and look like this ->

32 Hex No. and the name of the movie.
00000000000000000000000000000000_MOVIE_NAME.bin

[TTide]

I ran aacs_info and i found the convtab online.

aacs_info /run/media/gamer/MIKE_AND_DAVE_WEDDING_DATES/
MK: B4D2FA93A1174CED96ABC68F1935DB78

I started with a BD+ Disc example in .config/bdplus/convtab

B4D2FA93A1174CED96ABC68F1935DB78_MIKE_AND_DAVE_WEDDING_DATES.bin

This is what i ran but i don't know if it's the right way.

Usage: ./bdplus_diff [disc_root] [cached BD+ table] [obfuscated FUT output] [diff output]

./bdplus_diff -e /run/media/gamer/MIKE_AND_DAVE_WEDDING_DATES/ -c B4D2FA93A1174CED96ABC68F1935DB78_MIKE_AND_DAVE_WEDDING_DATES.bin -o B4D2FA93A1174CED96ABC68F1935DB78-FUTout -d B4D2FA93A1174CED96ABC68F1935DB78-diffout

Hopefully someone will help the process and tell me where i'm going wrong.

Hello,

I am using Linux (Debian 13 Trixie) and a Blu Ray Device thats connected via USB to a Lenovo M715Q (AMD Ryzen 5 Pro 2400GE, 8 GB RAM, 256 GB SSD). I made the aacs directory with the KEYDB.cfg and the bdplus directory with the vm0 directory (as described in the Linux section). Necessary libraries were installed via apt-get install.

Are the steps mentioned above for the Windows system necessary for the Linux system as well? I can play Blu Ray discs without menus via VLC but the graphical output which starts OK (Narnia, Voyage of the dawn treader, 20th Century Fox) turns buggy (lots of artifacts) after a few seconds. Its not a general playback problem as the playback of the disc starts. But where do I have to search the problem on my configuration?

Thank you in advance!

Kind regards

Frederik



Edit:
It works now, I adapted the KEYDB.cfg like mentioned in this post:

https://forum.doom9.org/showpost.php...1&postcount=10

And I downloaded the cached BD+ tables and placed the files in the convtab directory in .cache\bdplus ...
