vlcj：：无法在 64 位操作系统中加载库'libvlc'

Question

我使用64位操作系统Windows 7，我有32位VLC版本1.1.8。

我已经添加了这些库jna.jar platform.jar vlcj-1.1.5.1.jar

我不能使用jVlc流式传输

public class HelloVLC {
/**
 * @param args
 * @throws IOException 
 */
public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub
    System.out.println( WindowsRuntimeUtil.getVlcInstallDir());
      NativeLibrary.addSearchPath("libvlc", "C:\Program Files (x86)\VideoLAN\VLC");
      String media = "dshow://";
     String[] options = {" :dshow-vdev=Integrated Webcam :dshow-adev=  :dshow-caching=200", ":sout = #transcode{vcodec=theo,vb=800,scale=0.25,acodec=vorb,ab=128,channels=2,samplerate=44100}:display :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep"};
        System.out.println("Streaming '" + media + "' to '" + options + "'");
        MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory();
        final HeadlessMediaPlayer mediaPlayer = mediaPlayerFactory.newMediaPlayer();
        mediaPlayer.playMedia(media, options);
}

}

我得到错误Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'libvlc': The specified module could not be found.

请帮助。有没有办法让这个代码工作在64位操作系统????

Answer 1

您尝试过在32位JVM上运行它吗?

Answer 2

如果你使用的是Windows 7，那么在你的VLC安装中搜索libvlc.dll和libvlccore.dll文件，并将它们的路径添加到你在
中编写的代码中nativellibrary . addsearchpath()也添加…

这个方法在我的Windows 7中很有效。

 NativeLibrary.addSearchPath(
                RuntimeUtil.getLibVlcLibraryName(), ""c:/Program Files/VideoLAN/VLC/");
        Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
        LibXUtil.initialise();

VLCj具有独立于操作系统的自动发现方法，可将相关路径添加到JNA:s的搜索路径:

 NativeDiscovery nd = new NativeDiscovery();
 if (!nd.discover()) {
     System.out.println("VLC not found");
     System.exit(-1);
 }   
 String vlcLibName = RuntimeUtil.getLibVlcName();
 String vlcLibCoreName = RuntimeUtil.getLibVlcCoreName();
 Native.loadLibrary(vlcLibName, LibVlc.class);
