问题描述

我有这段代码可以流式传输一些视频

Hi i have this code to stream some videos

package video;
import javax.swing.*;

import java.awt.*;
import java.io.File;

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

import uk.co.caprica.vlcj.binding.LibVlc;
import uk.co.caprica.vlcj.component.EmbeddedMediaPlayerComponent;
import uk.co.caprica.vlcj.player.embedded.EmbeddedMediaPlayer;
import uk.co.caprica.vlcj.runtime.RuntimeUtil;
import uk.co.caprica.vlcj.runtime.x.LibXUtil;

/**
 * Source: Etienne Vachon

public class PlayerPanel extends JPanel {

    private File vlcInstallPath = new File("C:\\Program Files (x86)\\VideoLAN\\VLC");
    private EmbeddedMediaPlayer player;

    public PlayerPanel() {
        System.out.println(vlcInstallPath.getAbsolutePath());
        //NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), vlcInstallPath.getAbsolutePath());
        NativeLibrary.addSearchPath(
                RuntimeUtil.getLibVlcLibraryName(), vlcInstallPath.getAbsolutePath());
        Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
        LibXUtil.initialise();
        EmbeddedMediaPlayerComponent videoCanvas = new EmbeddedMediaPlayerComponent();
        this.setLayout(new BorderLayout());
        this.add(videoCanvas, BorderLayout.CENTER);
        this.player = videoCanvas.getMediaPlayer();
    }

    public void play(String media) {
        player.prepareMedia(media);
        player.parseMedia();
        player.play();
    }
}

我的vlc是64位，我的jvm也是如此，jna，jna平台和vlcj位于同一文件夹lib中.但是我每次都会收到此错误

My vlc is 64 bit and so is my jvm, the jna, jna-platform and vlcj are situated in the same folder lib. Yet i get this error every time

在异常显示的资源路径中看不到VLC路径是否正常?

Is it normal that i don't see the VLC path in the ist of ressources path displayed by the the exception ?

推荐答案

步骤1)安装VLC X64:

Step 1) Install VLC X64: https://get.videolan.org/vlc/2.2.6/win64/vlc-2.2.6-win64.exe

第2步)更改本机库路径:

Step 2) Change native library path:

File vlcInstallPath = new File("D:\\Program Files\\VideoLAN\\VLC");
