Question

我正在使用java CV进行视频流播放。我从网络摄像头捕获了视频。但是当我尝试将流传输到达尔文服务器时，它失败了。代码是，

package streamingapp;

import com.googlecode.javacpp.Loader;
import com.googlecode.javacv.CanvasFrame;
import com.googlecode.javacv.FFmpegFrameRecorder;
import com.googlecode.javacv.FrameGrabber;
import com.googlecode.javacv.OpenCVFrameGrabber;
import com.googlecode.javacv.cpp.avcodec;
import com.googlecode.javacv.cpp.opencv_objdetect;
import static com.googlecode.javacv.cpp.avutil.*;
import static com.googlecode.javacv.cpp.opencv_core.*;


public class StreamingApp {

public static void main(String[] args) throws Exception {

    Loader.load(opencv_objdetect.class);
    CanvasFrame frame = new CanvasFrame("webcam");
    FrameGrabber grabber = new OpenCVFrameGrabber(0);

    grabber.setImageHeight(500);
    grabber.setImageWidth(500);
    grabber.start();

    IplImage grabbedImage = grabber.grab();
    int width = grabbedImage.width();
    int height = grabbedImage.height();

    CvMemStorage storage = CvMemStorage.create();

    FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("rtsp://ipaddress:portno/testVideoStream.3gp", width, height);



    recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
    recorder.setFormat("rtsp");
    recorder.setFrameRate(grabber.getFrameRate());
    recorder.setVideoCodec(13);
    recorder.setPixelFormat(AV_PIX_FMT_YUV420P);
    recorder.setVideoBitrate(10 * 1024 * 1024);
    recorder.start();

    int i = 0;

    while (frame.isVisible() && (grabbedImage = grabber.grab()) != null) {
    System.out.println("(" + i++ + ") Invio. . .");
    frame.showImage(grabbedImage);
    recorder.record(grabbedImage);
    }

    cvClearMemStorage(storage);
    recorder.stop();
    grabber.stop();
  }

}

是否可以使用rtsp格式的javacv流式传输视频。

Answer 1

试试这个....我得到了结果（达尔文服务器）

FFmpegFrameRecorder recorder = new FFmpegFrameRecorder（＆＃34; rtp：// ipaddress：portno / testVideoStream.sdp＆＃34;，width，height）;

recorder.setVideoCodec(13);
recorder.setFormat("rtp");
recorder.setFrameRate(30);

//recorder.setPixelFormat(AV_PIX_FMT_YUV420P);
//recorder.setVideoBitrate(10 * 1024 * 1024);
recorder.start();

使用javacv将视频流传输到rtsp服务器
