VLCJ RTP流客戶端

我正在做一個基於VLCJ流的項目。我查閱了關於如何從下面的代碼創建服務器端的VLCJ教程。客戶如何從服務器獲取視頻內容？我也編寫了客戶端代碼，但它沒有顯示任何內容。VLCJ RTP流客戶端

任何幫助，將不勝感激。謝謝。

Server代碼：

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(); 
}

}

客戶端：

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）應顯示視頻內容，但沒有什麼是顯示。 JFrame只是空的。

你在客戶中玩的實際MRL是多少？ – caprica

嗨。感謝回覆。我的客戶中的實際MRL值是rtp：//@192.168.1.104：55555。我從另一臺計算機運行客戶端，它給了我這個錯誤：「打開'rtp：//@192.168.1.104：55555'失敗。」並且VLC無法打開MRL「rtp：//@192.168.1.104：55555」。任何建議，請。謝謝。 – khalidcawl

您原來的問題根據您的評論有5555作爲「公共」端口，而不是55555。 – caprica

我上面顯示的代碼的問題是服務器的IP地址。客戶端將連接到服務器，但VLC不會播放MRL。所以我在網上對螃蟹的例子進行了一些研究，發現我應該使用組播IP地址來與RTP進行流式傳輸。（例如230.0.0.1），問題就解決了。來自客戶端的流發生沒有問題。
