1) 下载安装nginx,我下载的版本是nginx-1.7.11.3-Gryphon(提取码:xj6f),下载完成后解压
2) 下载服务器状态检查程序(提取码:i6hw),下载完成后解压到nginx安装目录下
3) 在nginx解压目录下的conf文件夹中新建nginx-win-rtmp.conf 文件.

4) 在nginx的解压目录下运行命令提示框,输入nginx.exe -c conf\nginx-win-rtmp.conf 命令启动
org.springframework.boot

org.bytedeco

3.4.1-1.4.1
1. 推流服务
1) 创建工具类
public class RecordPush {
/**
* 推流器
* @param outputPath 接收路径
* @param v_rs 帧率
* @throws Exception
* @throws org.bytedeco.javacv.FrameRecorder.Exception
* @throws InterruptedException
*/
public void getRecordPush(String outputPath, int v_rs) throws Exception, org.bytedeco.javacv.FrameRecorder.Exception, InterruptedException {
Loader.load(opencv_objdetect.class);
//创建采集器
OpenCVFrameGrabber grabber = new OpenCVFrameGrabber(0); //本地摄像头默认为0
//开启采集器
try {
grabber.start();
} catch (Exception e) {
try {
grabber.restart(); //一次重启尝试
} catch (Exception e2) {
throw e;
}
}
OpenCVFrameConverter.ToIplImage converter = new OpenCVFrameConverter.ToIplImage(); //转换器
Frame grabframe = grabber.grab(); //获取一帧
opencv_core.IplImage grabbedImage = null;
if (grabframe != null) {
grabbedImage = converter.convert(grabframe); //将这一帧转换为IplImage
}
//创建录制器
FrameRecorder recorder;
recorder = FrameRecorder.createDefault(outputPath, 1280, 720); //输出路径,画面高,画面宽
recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264); //设置编码格式
recorder.setFormat("flv");
recorder.setFrameRate(v_rs);
recorder.setGopSize(v_rs);
//开启录制器
try {
recorder.start();
} catch (java.lang.Exception e) {
System.out.println("recorder开启失败");
System.out.println(recorder);
try {
if (recorder != null) { //尝试重启录制器
recorder.stop();
recorder.start();
}
} catch (java.lang.Exception e1) {
e.printStackTrace();
}
}
//直播效果展示窗口
CanvasFrame frame = new CanvasFrame("直播效果", CanvasFrame.getDefaultGamma() / grabber.getGamma());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setAlwaysOnTop(true);
//推流
while (frame.isVisible() && (grabframe = grabber.grab()) != null) {
frame.showImage(grabframe); //展示直播效果
grabbedImage = converter.convert(grabframe);
Frame rotatedFrame = converter.convert(grabbedImage);
if (rotatedFrame != null) {
recorder.record(rotatedFrame);
}
Thread.sleep(50); //50毫秒/帧
}
}
}
2) 创建启动类
/**
* @ClassName BroadcastApplication
* @Description : 启动类
* @Author : R
* @Date : 2020/8/17 17:18
*/
@SpringBootApplication
@Configuration
public class PushApplication {
public static void main(String[] args) throws Exception {
SpringApplicationBuilder builder = new SpringApplicationBuilder(PushApplication.class);
builder.headless(false).run(args);
System.out.println("---------------启动成功---------------");
//设置rtmp服务器推流地址
String outputPath = "rtmp://127.0.0.1:1935/live/stream";
RecordPush recordPush = new RecordPush();
recordPush.getRecordPush(outputPath, 25);
}
}
这里需要注意,需要在启动时做好配置,即把headless配置为false,否则启动时会报java.awt.HeadlessException异常
3) 运行推流服务,如果弹出窗口并且可以通过摄像头接收到画面,那么表示配置成功
2. 拉流服务
1) 创建工具类
public class PullStream {
/**
* 播流器
* @param inputPath rtmp服务器地址
* @throws Exception
* @throws org.bytedeco.javacv.FrameRecorder.Exception
*/
public void getPullStream(String inputPath) throws Exception, org.bytedeco.javacv.FrameRecorder.Exception {
//创建+设置采集器
FFmpegFrameGrabber grabber = FFmpegFrameGrabber.createDefault(inputPath);
grabber.setOption("rtsp_transport", "tcp");
grabber.setImageWidth(960);
grabber.setImageHeight(540);
//开启采集器
grabber.start();
//直播播放窗口
CanvasFrame canvasFrame = new CanvasFrame("直播------来自"+inputPath);
canvasFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
canvasFrame.setAlwaysOnTop(true);
OpenCVFrameConverter.ToMat converter = new OpenCVFrameConverter.ToMat();
//播流
while (true){
Frame frame = grabber.grabImage(); //拉流
opencv_core.Mat mat = converter.convertToMat(frame);
canvasFrame.showImage(frame); //播放
}
}
}
2) 创建启动类
/**
* @ClassName BroadcastApplication
* @Description : 启动类
* @Author : R
* @Date : 2020/8/17 17:18
*/
@SpringBootApplication
@Configuration
public class PullApplication {
public static void main(String[] args) throws Exception {
SpringApplicationBuilder builder = new SpringApplicationBuilder(PullApplication.class);
builder.headless(false).run(args);
System.out.println("---------------启动成功---------------");
//rtmp服务器拉流地址
String inputPath = "rtmp://127.0.0.1/live/stream";
PullStream pullStream = new PullStream();
pullStream.getPullStream(inputPath);
}
}
3) 推流服务不要停止的前提下,运行拉流服务,如果弹出窗口,并且可以接收到推流服务中的直播画面,说明拉流服务配置成功.
至此,一套简单的直播系统就完成了,看一下最后的结果展示吧.
