java VLCJ tutorial java.lang.UnsatisfiedLinkError

Question

I'm trying to use VLCJ, and got stuck on their first tutorial.

Here's my code:

package vlcj.tutorial1;

import uk.co.caprica.vlcj.binding.LibVlc;
import uk.co.caprica.vlcj.runtime.RuntimeUtil;

import com.sun.jna.Native;
import com.sun.jna.NativeLibrary;

public class Tutorial1A
{
    public static void main(String[] args)
    {
        // Ensure we're using the 32bit jdk.
        System.out.println("jdk version:  " + System.getProperty("sun.arch.data.model") + " bits.");

        NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), "C:/Program Files (x86)/VideoLAN/VLC/sdk/lib");
        Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
    }
}

Here's the output and exception I get:

jdk version:  32 bits.
Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'libvlc': The specified module could not be found.

at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:169)
at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:242)
at com.sun.jna.Library$Handler.<init>(Library.java:140)
at com.sun.jna.Native.loadLibrary(Native.java:368)
at com.sun.jna.Native.loadLibrary(Native.java:353)
at vlcj.tutorial1.Tutorial1A.main(Tutorial1A.java:17)

I made sure I'm using a 32 bit jdk and a 32 bit version of VLC.

Any ideas? Thanks in advance!

The code I have uses '{Install Path}/VideoLAN/VLC` (ie `C:/Program Files (x86)/VideoLAN/VLC`, but I also look for `libvlc.dll` and `libvlcore.dll` within the that folder to be sure — MadProgrammer, Dec 20 '12 at 00:10
@MadProgrammer that worked! Thanks very much :) If you want to chuck that comment in an answer I'll accept it. — Felix, Dec 20 '12 at 01:22

Try using {Install Path}/VideoLAN/VLC (ie C:/Program Files (x86)/VideoLAN/VLC) instead.

I look for libvlc.dll and libvlcore.dll within that folder to be sure that the libraries are installed, but that's just me ;)

Just changed `C:/Program Files (x86)/VideoLAN/VLC/sdk/lib` to `C:/Program Files (x86)/VideoLAN/VLC` and it worked :) Thanks again @MadProgrammer! – Felix Dec 20 '12 at 01:49
Yeah, it took a bit of head to desk interactions when I was trying to get it to work to :P – MadProgrammer Dec 20 '12 at 01:55

@PetroSemeniuk I was just lucky enough to have my library code at hand ;) – MadProgrammer Dec 20 '12 at 03:30
somehow it said : %1 is not a valid Win32 application." what is that VLC ? – gumuruh Nov 11 '21 at 08:58
@gumuruh Hard to say, my guess is you've got the wrong version (x64 instead of x32) – MadProgrammer Nov 11 '21 at 20:41
omg! you're correct! somebody installed the x32 bit under my x64 machine lately.... i will remove it and install a new one with x64 bit correctly now :D – gumuruh Nov 12 '21 at 06:55

Try to use double backward slash in path:

"C:\\Program Files (x86)\\VideoLAN\\VLC\\sdk\\lib"

instead of:

"C:/Program Files (x86)/VideoLAN/VLC/sdk/lib"
