VLC, makemkv and BD+

[legluondunet]

Hello,

I installed makemkv, use the libmmbd emulation to play my blu ray with VLC, all but the BD+.
VLC can not read BD+ with makemkv.
Is it a know issue?
VLC complained about a java error:

Code: Select all

I can reproduce this issue with all my BD+ played with vlc/makemkv and you?

I've had the same issue on Devuan Beowulf (which is basically Debian Buster). It was obvious to me that a necessary jar hasn't been loaded, I'm not sure though if the issue is with vlc or with libbluray-bdj. After searching for a while with `apt-file` and searching looking at the content of various jars, I found that the jars /usr/share/java/asm-7.0.jar and /usr/share/java/asm-commons.jar from the package libasm-java contained the necessary classes. I then did a little hack to temporarily fix this, I checked with `lsof /usr/share/java/*.jar` which jars had been loaded, and then decided to just merge one of those jars, namely libbluray-j2se-1.1.0.jar, with the other two. I did this as follows:

Code: Select all

sudo su - cd /usr/share/java/ mkdir tmp cd tmp unzip -uo ../libbluray-j2se-1.1.0.jar unzip -uo ../asm-commons.jar unzip -uo ../asm-7.0.jar jar -cvf combined.jar . cd .. mv libbluray-j2se-1.1.0.jar libbluray-j2se-1.1.0.jar.old mv tmp/combined.jar libbluray-j2se-1.1.0.jar

Please note that this could cause other problems and that it will probably stop working after the next update of libbluray-bdj.

Anyway, after that, the menus showed up and everything seamed to work fine for me.

You can override the bluray classpath with

Code: Select all

LIBBLURAY_CP=$(ls /usr/share/java/{asm-7*.jar,libbluray-j2se-*,asm-commons.jar} | paste -sd:) vlc bluray://$PWD

I forgot why this wasn't working when I looked at it earlier, the lookup is in https://code.videolan.org/videolan/libbluray/blob/master/src/libbluray/bdj/bdj.c#L515
