Has anyone gotten this to work?

Thanks,

I just tested Java 7 u1 (jdk1.7.0_01) 64 bits on Windows 7 Professional 64 bits, and gstreamer/gstreamer-java appear to work fine. You would need 64 bits binaries of gstreamer though.

I have tried 32-bit gstreamer-java with 32-bit Java 7 Update 1 on Windows 7 64-bit and I cannot get it to load the DLLs. It was working fine with Java 6 and the only thing I changed was upgrading Java.

What's the trick in getting it to work?

As long the dlls and the JVM have the same arch (32 or 64) bits, then gstreamer-java should work without any special tricks.

However, I only tested Java 7 64 bits with 64 bits dlls of gstreamer.

OK, I simply cannot get this to work.

My setup is GStreamer 0.10.6 32-bit, Java 7 Update 1 32-bit, Windows 7 64-bit. I have the GStreamer bin directory in my system path but when I run the examples in gstreamer-java-1.4 I always get this:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load library gstreamer-0.10

at org.gstreamer.lowlevel.GNative.loadWin32Library(GNative.java:83)

at org.gstreamer.lowlevel.GNative.loadLibrary(GNative.java:43)

at org.gstreamer.Gst.<clinit>(Gst.java:59)

at org.gstreamer.example.SwingMultiPlayer.main(SwingMultiPlayer.java:52)

That's what happens when I just run the program without specifying any DLL paths but I also get the exact same result when I run the program with the following VM argument:

-Djna.library.path="C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.6\bin"

I *really* need some help with this, I have to get it working and I have exhausted everything I can think of.

Any suggestions?

Thanks,

-Luc

I seem to have made a little progress...

Running the following command:

D:\Java\jdk\1.7.0-32\bin\java.exe -Djna.library.path="C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.6\bin";"C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.6\lib\gstreamer-0.10" -cp .;D:\Java\lib\gstreamer-java-1.4\lib\jna.jar org.gstreamer.example.SwingMultiPlayer D:\Media\nvidia.wmv

now gives me this error:

** (java.exe:12096): WARNING **: Failed to load plugin 'C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.6\lib\gstreamer-0.10\libgstrmdemux.dll': `C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.6\lib\gstreamer-0.10\libgstrmdemux.dll': The specified module could not be found.

The DLLs mentioned in this message do exist so what could be the problem with this?

Thanks,
