I can't convince java to find that damn shared library. I tried moving it around, added a java.library.path definition to the vmargs inside bdj.c but it still won't find that damn library .
Maybe your libqt3-mt.so.3 is not 32bit or some other dependencies of libqtawt.so are not met. I had to install the 32bit version of libqt3-mt.so.3 manually because i work on an amd64 system. From my notes:
Code:
http://www.boundlesssupremacy.com/Cappy/getlibs/getlibs-all.deb
getlibs -w http://ftp.de.debian.org/debian/pool/main/q/qt-x11-free/libqt3-mt_3.3.8b-5+b1_i386.deb
I can't compile the libqtawt.so (closed source?) and only the 32-bit version is available.

Anyway i recently switched from Java SE to ME and compiled the compact virtual machine (cvm) with debug flag so it's pretty verbose if something goes wrong. You can grab my binary snapshot from here. Run it with (adjust the paths):
Code:
./bin/cvm ${HOME}/bdplus/trunk/bdj/jni/libbdjinterface.so
The snapshot contains a standalone Java (microedition) installation so it shouldn't use any foreign jar files or stuff from other java installations. My player uses the cvm too and it's part of the BD-J standard.

If you want to compile it you will need the phoneme advanced mr2 snapshot. I had to merge the bdj.c with the phoneme source before compiling the cvm. Let me know if you need to know more details.

I'm running this on a 32 bit Ubuntu, ldd reports no missing libs. I've written a small java app which just loads the qtawt library and this works, don't know why it doesn't work from bdj.

Anyway, i've tried your cvm snapshot and had more success, qtawt is now loaded and i get a black window. During startup i got this error

Code:
"/home/<scrubbed>/bdj-cvm/lib/basis.jar" is not a valid classpath zip file or directory.
which i fixed by renaming basis_security.jar.

The cvm runs but fails to load any BD-J applet from the disc. The path to my drive matches the hardcoded path so this isn't the problem. I can't remember you ever mentioned which disc you are using, i assume we are talking about X-Files here because your posted 77770.jar matches almost the one from my disc (but there are differences, i think because i don't have your version of the movie and i remember Anydvd was updated to support a different version of X-Files), but i don't have 99900.jar (and no directory with that name) on my disc.

These are the error messages from loading the 99900.jar file, loading the 77770.jar produces the same ones:

It doesn't load the jar files from the disc. Instead you have to copy them to "/tmp/BDJRoot/" (both the 77770.jar and 99900.jar). That directory is the local application cache which can change over time when using BD-Live. It will extract a part of the jar archives inside the "DOCR/signed/" subdirectory. I don't fully understand this yet.

It's "The Day The Earth Stood Still" and you can download the content of the JAR directory from posting #645.

I'm glad to see you made it this far. You should get a bit further with both jar files in the /tmp/BDJRoot/ directory but there will be null pointer exception (certificate == null?) soon afterwards.

A good way to proceed is to edit the com.cl.bdj.helper.* classes (inside the bdj.jar) to make them print out a console message of the actual value/string they got from the native methods they called. For example:
Code:
invokestatic com/cl/bdj/util/BDJTrace/info(Ljava/lang/String;)V
will print the string you pass as parameter plus the class and method name from which it is called.
The additional debug output i get when using the modified bdj.jar helps me to correct the bugs in the native interface. My source code C files are named after the helper classes as you might have noticed.

The classes in the "btclasses.zip" archive have been merged into the cvm binary (ROMization) to boost performance. That causes some problems because some of these classes have been customized by the vendor of my player. For example a "extractJar" method has been added to the java.util.jar.JarFile which is therefor missing in the cvm i compiled. I have several options in this case and will try them all.
I also managed to patch all methods which call native code and return boolean, int or string. I also succeeded in attaching a debugger (jdb) to the cvm to monitor the BD-J implementation. It's quite complex.

Progress is slow because i'm working alone on this. So be patient.

I finally got the BD+ handshake application loaded and running:

called Java.com.cl.bdj.helper.BDJVFSHelper.RegisterAccessHelper.pTriggerPSR103change -> NOT IMPLEMENTED!
The application (com.macrovision.bdplus.Handshake) sets PSR103 to 0xF1000000 and PSR104 to 0 as expected (see first lines of posting #642). The following call "pTriggerPSR103change" probably places a trigger on PSR103 so the thread resumes once the content code is done with its changes. I don't know the exact mechanism yet.

You can download the binary snapshot here.

Steps to reproduce:
1. mount the disc at "/media/cdrom/" (certificate will be verified)
1. place the 77770.jar and the 99900.jar in the directory "/tmp/BDJRoot/" (see posting #645)
2. create a directory "/DOCR/" (root directory -> i couldn't move it into the "/tmp/" folder)
3. make sure both directories have user write permission (stuff will be written into both directories by the java code)
4. run: "./bin/cvm ${HOME}/bdplus/trunk/bdj/jni/libbdjinterface.so" <-- adapt to your directory structure

Edit: the "bdj.c" in the archive is slightly different from the version i used to create the cvm (debugging with jdb is currently disabled).

After the content code wrote PSR102 the player executes command 8 (native code calls java method "executeCommand") which creates a BDPlusStatusEvent object. The constructor gets the contents of PSR102 as parameter. The status event object is then passed to the application. The "pTriggerPSR103change" call might cause BD+ event#0210.

I'll run some tests to see if the handshake works properly. If successful i can start merging this into libbluray.

It seems to be working. Below are the relevant sections of the console output. You should compare this with posting #642 (look for the correct return "BC79595F 97F05643 07A0ABF2 CC10F7C5")

So we should probably start creating a libbdj which can be used in conjunction with libbluray to repair the latest batch of BD+ corrupted discs.

Btw the handshake application needs additional jar files but these are fetched automatically from the disc after i changed the VFS root to /media/cdrom.

You're doing an excellent job loo3aem3ON! And I would gladly help. But I'm afraid I don't know much about Java, and pretty much anything else discussed in this thread.

Just wanted to give you an encouraging word, and keep up the excellent work!

Thanks. You can help by grabbing the latest binary snapshot and playing around with it. Then report the problems you encounter.

About 80% of BD-J is implemented in java and this part can be copied from any Blu-Ray player without modifications. The rest are native functions which have to be implemented in C/C++ or whatever. Of particular interest are the functions which are used to indirectly talk with the BD+ content code via the player status registers (PSR) 102-104.

I don't know how difficult it is to get the menus working. A black window pops up in the top left corner of the screen but it isn't filled with contents because that's being done by the second application which i haven't yet tried to start. The primary goal was to get the first application (BD+ handshake) running.

This is great news, the progress you and the others working on this project have made in the last few weeks is more then the entire Linux community efforts combined for the last…o 6 moths or so. The guys here on the doom9 forums have almost successfully reverse-engineered the VM completely and now you are braking down the walls for BD-J in order to completely bypass BD+. An amazing feat if you ask me considering the relatively short amount of time you guys have been working on this. As to your comments regarding getting a full BD-J library in development, I feel this is the next logical step as it will be needed to get BD+ is fully handled. This is not to mention the fact that once we have an operational BD-J library, we would more or less have fully functional menu support under Linux with relatively little effort compared to what has already been done.

Keep up the good work guys!

Slice

P.S. something that might be nice to get more people testing this stuff is to make it easily and openly available, maybe precompiled and available for download from a repository for Linux. Also, basic step by step instructions on how to use these tools is not readily available so that might be something to consider.

P.P.S. I have not followed the progress of AACS very closely, has it been completely broken yet or are we still stuck only being able to decrypt titles that feature MKBv7 or earlier?

@ Slice:

as of now we (Linux users) are only able to decrypt titles that are MKBv8 and earlier. We don't have processing keys for MKBv's beyond that. Although Mike Chen of the MakeMKV project claims that they have keys that may be able to go as far as MKBv11:

http://forum.doom9.org/showthread.ph...79#post1242679

but he hasn't yet responded to a request to share these keys with KenD00 (for DumpHD).

[edit: make that MKBv12: http://forum.doom9.org/showthread.ph...98#post1248998]

AACS most probably will never be broken and there will be always the hunt for new keys.

Hi,
where I can find the source code of this project. Maybe you could host this project on https://launchpad.net/ ? There you can make an bazaar repo so others could hack on the code too!? I could help you to register and host this project on Launchpad. I can also provide you help for Debian/Ubuntu packaging. I would be glad to helping this project

I don't think "bypassing" BD+ is possible. We are doing exactly what all the licensed Blu-Ray players are doing.

Hopefully

You can find full build/binary snapshots in my previous postings.

Will do.

I would be a careful with such statements. Even if no weakness can be found (which i think is unlikely) the underlying AES cipher is losing 1 bit of its security every 18 months (Moore's law).
Well maybe by the time AES becomes insecure we will all have DRM modules implanted in our brains.

No thank you.

It's currently hosted at assembla: https://trac.assembla.com/bdplus/

I'm currently quite happy with assembla but it might be a good idea to move the BD-J part (trunk/bdj) to a different repository.

AACS needs to added to libbluray (currently BD+ only). The maintainer (Accident) is busy at the moment. You could help by finding volunteers to help with the project.
I need to explain and simplify the environment for BD-J so more people are willing to experiment. The directory structure needs to be explained (eg. BUDA = "Binding Unit Data Area" etc). Furthermore some of the native functions return data specific to the movie "The Day The Earth Stood Still".

The BD-J platform development project is now hosted at https://launchpad.net/bdj.

The method "readBDJO" (trunk/src/bdjo/BDJOReader.cpp) and its dependencies need to be ported from java to C++. I've already renamed all the file extensions. The conversion from and to XML is irrelevant. Have a look at the method names in "AppsDatabaseHelper.c" and you will see why.

The native code first needs to parse the index.bdmv to obtain the FirstPlaybackmobjidref (name of a BD-J object in the BDJO/ directory) and then parse the identified *.bdjo file.
At the moment the data from the 07777.bdjo is hardcoded in the methods of "AppsDatabaseHelper.c" so other applications from other Blu-Rays won't work. Furthermore the AppCacheInfo section of this BD-J object contains a list files which have to be loaded into the local cache (which i called "/tmp/BDJRoot/") for fast access. Currently these files have to be copied manually. So you see how important it is to read these BD-J objects properly.
Reading the index.bdmv is not a problem.

I want to apologise not being of much help lately. Large equipment failure that I got the honour to fix. But I can do code just fine when we have new things to solve, but no time to help with the in-depth research. On related news, I actually ended up with a BD player and a couple of disks, so it will be fun to be able to some experience actually playing a disk.

Related to libaacs, and libbluray, I was thinking of keeping the libraries separated, but write some example sources that uses both libraries, and massage them to play together nicely. I may end up checking in libaacs since its maintainer appears to be MIA. I have version 0.05.

That's the latest binary/build snapshot containing the libraries missing from the launchpad repository: Download.
Start it simply with "sh run.sh". The disc has to be mounted at "/media/cdrom". It probably won't run far so don't be disappointed (see my previous posting for an explanation). I'm working on it.

@Accident:
Focus on libaacs then and maybe rename libbluray to libbdplus.

Helping test

Is there any way to help test this code without the actual use of an blu-ray phisical reader? I do not have an blu-ray unit but I would gladly help in case there is any test work that needs to be done.

It doesn't require the physical disc. You can copy these files/directories to /media/cdrom/ (path is currently hardcoded as well) :
Code:
CERTIFICATE/app.discroot.crt
CERTIFICATE/bu.discroot.crt
BDMV/index.bdmv
BDMV/BDJO/*
BDMV/JAR/*
None of these files are encrypted. At least one *.jar file has to be present in BDMV/JAR/ otherwise there is no application to execute.

See if you can find these files somewhere. Otherwise i could send you those from my disc.
