Add built-in Java support

And those are definitely BDJ-Menus?

blob810 · March 19, 2018 at 8:33 PM

There are lot of files in the BDJO and JAR folders. So i think it´s BDJ.

novalis · March 19, 2018 at 8:40 PM

So which image did you flash and which Mil version?

blob810 · March 19, 2018 at 8:42 PM

Everything from this Post Add built-in Java support

After installing the addon restart.

And in the settings switch to simplified menu. After you click on a ISO Image or bluray Disk choose in the simplified menu play Bluray Menu.

So you did not install on a RasPi?

Adding jre to Generic project is simple as writing this post

It´s only for Generic systems. You need the version of java for ARM processors, but I don´t know if its working on the Pi.

Maybe vpeter has a solution for you.

novalis · March 19, 2018 at 8:53 PM

yes, didn't remeber that. "Java as addon was already done (for Generic only)."

Sorry but vpeter doesn't have any RPi. Which means I'm not looking how to run java there

Oracle is offering a special Java ARM package on their webpage called "Linux ARM 32 Hard Float ABI". The 64 bit version is also there. Is there any chance to implement this in an add-on package for LIBREELEC on RPi? I am not a programmer but I can offer my support for testing of alpha / beta versions.

**vpeter** · April 5, 2018 at 8:34 AM

Until someone tries we will not know

But as I wrote addon also needs some shared libs which was copid from Ubuntu for Generic. But for RPi it should be copied from maybe Raspbian or ideally build on LibreELEC.

Cool , hope someone with skills can build a test addon/ build for Rpi 🙂

blob810 · April 14, 2018 at 8:49 PM

I tried to install it on rpi3. I compiled Libbluray from scratch on the raspberry pi in respbian. And I also copied the libraries from respbian. Installed it on libreelec as an add-on. But when I try to play a file with disc menu I got a spinning wheel.

Edit: For java I took the jdk-8u161-linux-arm32-vfp-hflt.tar.gz

You are missing library libXext.so.6 because of

vpeter thanks for your help

Bluray Menus are working on my Raspberry Pi 3. Tested with Milhouse Build 0407.

I uploaded the package on my private server, hope thats ok.

Code

wget https://juka-blog.de/wp-content/uploads/2018/04/bluray-menu-rpi2.tar.gz
tar xzf bluray-menu-rpi2.tar.gz -C /
rm bluray-menu-rpi2.tar.gz

Nice work you two 😀

Could the addon also be made for Amlogic s905?

Great.

Tell me something: From what I see you copied only jre folder from jdk-8u161-linux-arm32-vfp-hflt.tar.gz? Correct?

Don't have such device which means it is the same story as with RPi: Maybe someone will investigate. But I'm sure it could be done.

Maybe you could try above RPi2 version.

blob810 · April 17, 2018 at 7:43 AM

I copied the JRE from the dk-8u161-linux-arm32-vfp-hflt.tar.gz and renamed it to JRE1.8.0_161. Create a symlink from JRE to JRE1.8.0_161.

Also I recompiled the Libbluray.jar on respbian. But I think that is not necessary. Last I copied the the libs inside the lib folder. Also from raspbian os.

I hope its possible to integrate it in the final images of libreelec 9.
