悄摸直播 —— JavaCV实现本机摄像头画面远程直播

推流器

一、功能说明

获取pc端的摄像头流数据 + 展示直播效果 + 推流到rtmp服务器

二、代码实现

/*** 推流器* @param devicePath   摄像头的地址。可以是摄像头rtsp地址，也可以是设备号码，本机摄像头是0* @param outputPath   接收路径* @param v_rs         帧率* @throws Exception* @throws org.bytedeco.javacv.FrameRecorder.Exception* @throws InterruptedException*/public static void recordPush(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) {// TODO Auto-generated catch blocke.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}}

三、测试推流器

public static void main(String[] args) throws Exception, org.bytedeco.javacv.FrameRecorder.Exception, InterruptedException {//设置rtmp服务器地址String outputPath = "rtmp://192.168.1.48:1935/live/stream";recordPush(outputPath, 25);}

如果出现“直播效果”的swing窗口，并能够播放摄像头画面，则说明推流器成功。
