How to use jvlc-core-0.9.0-SNAPSHOT-20080727.jar in other path ? And as library in Eclipse or Netbeans?

Thanks.

if you use netbeans, set:
project properties/run/working directory to "C:\Program Files\VideoLAN\VLC\"
and vm options to -Djna.library.path="C:/Program Files/VideoLAN/VLC/plugins"

(in eclipse is really the same)

Gonzalez,

You can also run the command:
NativeLibrary.addSearchPath("libvlc", PATH_WHERE_THE_JVLC_DLLS_ARE);
NativeLibrary.addSearchPath("jvlc", PATH_WHERE_THE_JVLC_DLLS_ARE);

But you'll proably get the same problem as me.
The "original" vlc binaries doesn't seem compatible with JVLC, which requires the jvlc.dll and a libvlc.dll that appears to be VERY different from the one that comes with VLC, as the libvlc that comes with VLC has ~ 100KB and the libvlc.dll that comes with the JVLC version I have has ~ 1,6 MB.

Right now I gave up finding a pair of jvlc_jar / jvlc_dlls (or .so) and I'm trying to build a previous version of vlc under Linux on my own, but still no success...

othon200,

i downloaded a fresh install of vlc for windows (http://www.videolan.org/mirror-geo.php? ... -win32.exe) and it works with those jvlc.jar which i compiled from git source. without any dll. theres is no jvlc.dll (what is it?)

maybe you are need a complete, buildable, working example of jvlc? if i have a little time, i can give to you

Hello,

I'm having similar problems making this thing run at all.

All the files I've downloaded I can't seem to make them run with java... (I'm using JDK 1.5.0_16, for project compatibility reasons).

The only zip that somewhat worked is the jvlc-binary-windows-x86-20070310.zip, which came with a vlc.exe file that brought up a command line interface.

I would really appreciate some help in this matter, there are a handful of people that seem to have gotten jVLC up and running.

I know it's a lot to ask, but maybe if we trade the information we can create a step by step guide for future reference.

What I noticed in the zips and tars I've downloaded is that most of the documentation is outdated (some win32 versions have a README that says that jVLC doesn't work under windows).

My main goal is to get it up and running under Linux, so if it won't work that's ok.

My specs: Ubuntu 8.04.1 Hardy, JDK 1.5.0_16, VLC 0.9.2, jVLC (0.0.8 and 0.0.9, both binary and source files).

Any help is greatly appreaciated.

Best Regards,
Fabio

It does work on windows, but as xyber mentioned you have to adjust your path to enable jvlc/jna to find the libvlc libaries and you need to specify the path to the plugins' dir, to enable libvlc to find the plugins. Setting -Djna.library.path does not work for me.

To run the example from a console:

Code: Select all

set PATH=%PATH%;path\to\vlc java -cp jvlc-snapshot[...].jar org.videolan.example.VLCExample --plugins-path="path\to\vlc\plugins"
In Eclipse you can add the path to run configuration in the enviroment tab and again you need to pass --plugins-path to the JVLC Consturctor.

It works. I will take look at source code to learn how to make it works.

Thanks.

NativeLibrary.addSearchPath("libvlc", PATH_WHERE_THE_JVLC_DLLS_ARE);
NativeLibrary.addSearchPath("jvlc", PATH_WHERE_THE_JVLC_DLLS_ARE);
I put this code inside the VLC example and doesn't work and also try System.setProperty("jna.library.path",PATH_WHERE_THE_JVLC_DLLS_ARE) and i get

Code: Select all

java.lang.UnsatisfiedLinkError: Unable to load library 'libvlc'
It only works if i set working directory in Netbeans project , Is there any way to set jna library search path dinamically?

unsatisfied link means path is wrong or some other environment problem.

I see that if you open a video file , then stops and open other video file , the VLC example always play the same video file (the first you choose).

Any way to play the other file?

you have a path problem. run it from "C:/Program Files/VideoLAN/VLC/"
I've tried "--plugin-path=D:\" and "--plugin-path=D:/". The libvlc.dll is in the D:\ folder. And I still get the UnsatisfiedLinkError, unable to get the library 'libvlc' loaded.

Running WinXP, Eclipse 3.4.1. Help? Thanks.

I have exactly your stats. The solution? add the path to the VLC folder (in program files) to the system-variable %PATH%. Go to run configuration in eclipse, environment, select variable path and add
;c:/program files/Videolan/VLC
or something to it at the end. This is a quick scratch of how to do it...
