VLC plays menus from disc but not backup dir.

[Mahagonnybill]

I have been archiving my BD collection for a NAS based media server. I like having the disc menus available and have been working with MakeMKV's backup function. Using VLC for playback I have found that some discs will play fine with menus but when I make a decrypted backup of the disc, VLC can not open the menu.

I am now wondering if I am using the backup function correctly. Has anyone else been able to open BD menus with VLC on both the disc and a backup folder?

You should be able to play the backup in VLC with menus with a command like this:

Code: Select all

vlc "bluray:///F:\Videos\backup\Movie"

When I open the disc from the command line I get the following and the menu plays:

> vlc bluray:///PATH/TO/DEVICE

It looks like VLC is loading the required Java libraries when I load the disc, but getting a java.lang.NoClassDefFoundError when I load the backup.
