Ubuntu VLC use MakeMKV

[chihwahli]

The instructions in here are to vague. I really have no clue where to execute the command to create an symbolic link.
I do not care if I have double the same files, I just need it to work.
viewtopic.php?f=10&t=7008

I installed MakeMKV with the instructions:
viewtopic.php?t=224

my file location: /usr/lib/libmmbd.so.0
In this directory inside terminal , I execute command: sudo ln -s libmmbd.so.0 /usr/lib/
I get message: ln: Already exists

Please someone. Where must I execute this command, or is there an alternative way to solve this? The instructions are really not clear. I am just a user, instructions must be crystal clear.

Please try this instead :

Open a terminal inside the /usr/lib folder (as you previousy did)

Then :

Code: Select all

sudo rm libaacs.so.0 libbdplus.so.0

Ignore any error messages, this is just a precaution to remove any faulty links, just in case.

Then, in the same terminal and the same folder :

Code: Select all

sudo ln -vs libmmbd.so.0 libaacs.so.0

and then, also in the same terminal and the same folder :

Code: Select all

sudo ln -vs libmmbd.so.0 libbdplus.so.0

You shouldn't need to create the symlink unless you have some ancient system / libbluray though.

What you better make sure / check beforehand is that MakeMKV can work (rip to MKV / make decrypted backup). For example, you need to "register" first, as in, entering beta / permanent key to "activate' all functons, or start the trial period. Also, for UHD BD / non-LibreDrive, Hashed Keys need to be downloaded (it might be slow / fail because of geoblocking). sdf.bin update stalling might also prevent it from working.

In other words, make ripping / decrypted backup attempt before you play directly. (You can stop it once you see the main content being ripped.)

On my Noble Numbat-based distro, I most certainly did need both symlinks.

EDIT : Please note that it's also not recommended to use your Blu-ray drive to play discs directly in a repeated manner, as this will cause unnecessary laser wear-and-tear. On the other hand, my guess is that if you have, say, a ton of Blu-ray discs from a TV series that you couldn't possibly rip because you lack the storage space needed for all of them, then you might want to go for it.

I'm using the flathub version.

It installs to:

/var/lib/flatpak/app/com.makemkv.MakeMKV

The lib is in:

/var/lib/flatpak/app/com.makemkv.MakeMKV/current/active/files/lib/libmmbd.so.0


Soo the command would be:


sudo ln -s /var/lib/flatpak/app/com.makemkv.MakeMKV/current/active/files/lib/libmmbd.so.0 /usr/lib/libmmbd.so.0

that will create a symlink (shortcut) that points from your lib folder to the lib itself.

No idea. Apparently the last non-Windows libmmbd commit dates back to 2017 (1.0.2), with 1.3.4 being the version Noble ships. A quick check doesn't seem to show that the libmmbd loading logic is being patched out or disabled whatsoever in Ubuntu.

EDIT: although IIRC under certain cirumstances libaacs could "stall" instead of just "fail", in which case would prevent libmmbd from "kicking in". (To be frank, instead of overwriting the files with symlinks, uninstalling libaacs and libbdplus properly might be a better thing to do -- should be possible for "Recommend"?)

Good point - I assumed this to already be the case for chihwahli, but I probably should have mentioned that to them. The reason I posted this :

Code: Select all

sudo rm libaacs.so.0 libbdplus.so.0

was more in the very unlikely case chihwahli could have, say, manually created faulty links with due to typos or something before reading my post. Just a silly precaution on my part, really.

It's not just Ubuntu, it would seem. Even with my Arch distrobox with Kodi, VLC and MakeMKV, direct 4K Blu-ray disc playback wouldn't work before I created the symlinks...
