[英]Run example RTSP with vlcj example (JAVA)
I try to open a video stream from a RTSP server into a JAVA application. 我尝试从RTSP服务器打开视频流到JAVA应用程序。 First I tried to run this example :
首先,我尝试运行此示例:
package uk.co.caprica.vlcj.test.streaming;
import uk.co.caprica.vlcj.player.MediaPlayerFactory;
import uk.co.caprica.vlcj.player.headless.HeadlessMediaPlayer;
import uk.co.caprica.vlcj.test.VlcjTest;
/**
* An example of how to stream a media file using RTSP.
* <p>
* The client specifies an MRL of <code>rtsp://@127.0.0.1:5555/demo</code>
*/
public class StreamRtsp 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 options = formatRtspStream("127.0.0.1", 5555, "demo");
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"
);
// Don't exit
Thread.currentThread().join();
}
private static String formatRtspStream(String serverAddress, int serverPort, String id) {
StringBuilder sb = new StringBuilder(60);
sb.append(":sout=#rtp{sdp=rtsp://@");
sb.append(serverAddress);
sb.append(':');
sb.append(serverPort);
sb.append('/');
sb.append(id);
sb.append("}");
return sb.toString();
}
}
But I have always the same result : Specify a single MRL to stream 但我总是得到相同的结果:指定一个MRL来流式传输

Even if I delete this section : 即使我删除此部分:
if(args.length != 1) {
System.out.println("Specify a single MRL to stream");
System.exit(1);
}
Can you help me please ? 你能帮我吗 ?
Sounds like you're not actually passing an argument to the program, which it expects from this line: 听起来你实际上没有将参数传递给程序,它希望从这一行:
String media = args[0];
If you don't want to pass an argument, just change it to: 如果您不想传递参数,只需将其更改为:
String media = "(location of rtsp to stream)";
...and delete the if statement above it as you already have. ...并删除它上面的if语句。
This is a full example with java, include a Java class for streaming (no need to create other functions) 这是一个完整的java示例,包含一个用于流式传输的Java类(无需创建其他函数)
This is an example for a simple streaming : 这是简单流式传输的示例:
StreamRTP rtp = new StreamRTP();
rtp.start("10.20.11.142", 5000, "sample.mp3");
