Java for the container?

[IDtheTarget]

Some of the blu-ray disks I buy show dozens or more titles, all but one with the sequences out of order. Supposedly getting Java to work with MakeMKV is one way to fix the problem: https://www.makemkv.com/bdjava/

I'm absolutely new to Docker (I've gotten this container working on TrueNAS Scale 24.10 Electric Eel, but that's it). Is this something you'd add? Or something I'd have to figure out how to add to the docker container?

Thank you!

Yes, Java is part of the container should work out of the box.

I apologize, I should have checked. I just opened a shell in the docker and ran java -showversion and got "openjdk version 1.8.0_392". The thing that's confusing me is that I'm trying to rip John Wick 3 and I'm getting the long list of false playlists and none of them have the title change with the "main title" or what have you. After seeing your reply (thank you, by the way!) I used which java to see that it's in /usr/bin so I went into the "protection" tab in MakeMKV and added /usr/bin/java to the custom Java executable location and I'm still getting the same list of false titles with no java title updates. I logged into the shell again and did an env and I'm not seeing a JAVA_HOME variable, could that be the problem? I tried doing an ls -alh /usr/bin/java and see that it's a link to /lib/jvm/default-jvm/bin/java, but when I tried going there to see if I could use it for JAVA_HOME, I keep getting "no such file or directory"

Sorry if I'm a pain, just trying to get this to work.

In MakeMKV preferences, can you enable Log debug messages and see what you have when you open the disc? The messages should indicate if Java has been executed.

That is very odd. I removed the Custom Java executable location and I'm seeing that MakeMKV is stating that it's using Java (Using Java runtime from /usr/lib/jvm/java-1.8-openjdk/bin/java), but I'm still not seeing any of the titles with "MainFeature" or any other title alteration. So I thought I'd check some variables. I put the John Wick blu-ray in my other reader and got the same result.

Then I put "Ghostbusters Frozen Empire" in the first drive, and I'm getting the expected Java titles:

So I have to assume that the problem lies in the movie and not the custom app.

I also would like to say "Thank you!" for not only the amazing support you've provided (on Thanksgiving day, no less!) but also on the wide array of useful custom apps. You've singlehandedly provided replacement apps for everything I was using True Charts for.

Thank you again, and I hope you have a great rest of your weekend. I'm going to mark your above response as the answer because, like I said, I think the problem is with the disk and not your app.

You can also look at the MakeMKV forum (https://forum.makemkv.com/forum/), where this particular movie is discussed a lot: https://forum.makemkv.com/forum/viewtopic.php?p=78051#p78051
