VLCJ RTP流客户端

我正在做一个基于VLCJ流的项目。我查阅了关于如何从下面的代码创建服务器端的VLCJ教程。客户如何从服务器获取视频内容？我也编写了客户端代码，但它没有显示任何内容。VLCJ RTP流客户端

任何帮助，将不胜感激。谢谢。

Server代码：

package com.khalid.VideoStreaming; 

import uk.co.caprica.vlcj.player.MediaPlayerFactory; 
import uk.co.caprica.vlcj.player.headless.HeadlessMediaPlayer; 


public class PublicServer extends VlcjTest{ 
public static void main(String[] args) throws Exception { 
    if (args.length != 1) { 
     System.out.println("Specify a single MRL to stream"); 
     System.exit(1); 
    } 

    String media = args[0]; 
    //String publicIP = "192.168.0.255"; 
    String publicIP = "192.168.1.104"; 
    short publicPort = 5555; 
    String options = formatRtpStream(publicIP, publicPort); 

    System.out.println("Streaming '" + media + "' to '" + options + "'"); 

    MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory(args); 
    HeadlessMediaPlayer mediaPlayer = mediaPlayerFactory.newHeadlessMediaPlayer(); 

    mediaPlayer.playMedia(media, options, ":no-sout-rtp-sap", ":no-sout-standard-sap", ":sout-all", ":sout-keep"); 

    Thread.currentThread().join(); // Don't exit 
} 

private static String formatRtpStream(String serverAddress, short serverPort) { 

    StringBuilder sb = new StringBuilder(200); 
    //sb.append(":sout=#transcode{acodec=mp4a,samplerate=12000,width=400,height=300}:rtp{dst="); 
    //sb.append("::sout=#transcode{vcodec=mp4v,vb=4096,scale=1,fps=30,acodec=mpga,ab=128,channels=2,samplerate=44100,width=800,height=600}:rtp:duplicate{dst=file{dst="); 
    sb.append("::sout=#transcode{vcodec=mp4v,vb=3000,fps=30,scale=1,acodec=mp4a,ab=128,channels=2,samplerate=48000,width=800,height=600}:rtp{dst="); 

    sb.append(serverAddress); 
    sb.append(",port="); 
    sb.append(serverPort); 
    sb.append(",mux=ts}"); 
    return sb.toString(); 
}

}

客户端：

String mediatorIP = "192.168.1.104"; short mediatorPort = 6001; 
String publicIP, publicServer, localIP, localServer, clientIP; 
short publicPort, localPort; 

MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory(args); 
EmbeddedMediaPlayer mediaPlayer = mediaPlayerFactory.newEmbeddedMediaPlayer(); 

Canvas canvas = new Canvas(); 
canvas.setBackground(Color.black); 
CanvasVideoSurface videoSurface = mediaPlayerFactory.newVideoSurface(canvas); 
mediaPlayer.setVideoSurface(videoSurface); 

JFrame f = new JFrame(); 
//f.setIconImage(new ImageIcon(Client.class.getResource("icons/vlcj-logo.png")).getImage()); 
f.add(canvas); 
f.setSize(800, 600); 
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
f.setVisible(true); 
publicIP = inFromServer.readLine(); // Recv public server's ip from mediator 
publicPort = Short.parseShort(inFromServer.readLine()); // Recv public server's port from mediator 
publicServer = formatRtpStream(publicIP, publicPort); 
System.out.println("Capturing from '" + publicServer + "'"); 
f.setTitle("Capturing from Public Server 'rtp://" + publicIP + ":" + publicPort + "'"); 
mediaPlayer.playMedia(publicServer);

正如你可以在上面看到，mediaPlayer.playMedia（publicServer）应显示视频内容，但没有什么是显示。 JFrame只是空的。

你在客户中玩的实际MRL是多少？ – caprica

嗨。感谢回复。我的客户中的实际MRL值是rtp：//@192.168.1.104：55555。我从另一台计算机运行客户端，它给了我这个错误：“打开'rtp：//@192.168.1.104：55555'失败。”并且VLC无法打开MRL“rtp：//@192.168.1.104：55555”。任何建议，请。谢谢。 – khalidcawl

您原来的问题根据您的评论有5555作为“公共”端口，而不是55555。 – caprica

我上面显示的代码的问题是服务器的IP地址。客户端将连接到服务器，但VLC不会播放MRL。所以我在网上对螃蟹的例子进行了一些研究，发现我应该使用组播IP地址来与RTP进行流式传输。（例如230.0.0.1），问题就解决了。来自客户端的流发生没有问题。
