代码：
public static void recordCamera(String outputFile, double frameRate)
throws Exception, InterruptedException, org.bytedeco.javacv.FrameRecorder.Exception {
Loader.load(opencv_objdetect.class);
FrameGrabber grabber = FrameGrabber.createDefault(0);//本机摄像头默认0，这里使用javacv的抓取器，至于使用的是ffmpeg还是opencv，请自行查看源码
grabber.start();//开启抓取器
OpenCVFrameConverter.ToIplImage converter = new OpenCVFrameConverter.ToIplImage();//转换器
IplImage grabbedImage = converter.convert(grabber.grab());//抓取一帧视频并将其转换为图像，至于用这个图像用来做什么？加水印，人脸识别等等自行添加
int width = grabbedImage.width();
int height = grabbedImage.height();
FrameRecorder recorder = FrameRecorder.createDefault(outputFile, width, height);
recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264); // avcodec.AV_CODEC_ID_H264，编码
recorder.setFormat("flv");//封装格式，如果是推送到rtmp就必须是flv封装格式
recorder.setFrameRate(frameRate);
recorder.start();//开启录制器
long startTime=0;
long videoTS=0;
CanvasFrame frame = new CanvasFrame("camera", CanvasFrame.getDefaultGamma() / grabber.getGamma());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setAlwaysOnTop(true);
Frame rotatedFrame=converter.convert(grabbedImage);//不知道为什么这里不做转换就不能推到rtmp
while (frame.isVisible() && (grabbedImage = converter.convert(grabber.grab())) != null) {
rotatedFrame = converter.convert(grabbedImage);
frame.showImage(rotatedFrame);
if (startTime == 0) {
startTime = System.currentTimeMillis();
}
videoTS = 1000 * (System.currentTimeMillis() - startTime);
recorder.setTimestamp(videoTS);
recorder.record(rotatedFrame);
Thread.sleep(40);
}
frame.dispose();
recorder.stop();
recorder.release();
grabber.stop();
}
public static void main(String[] args) throws Exception, InterruptedException, org.bytedeco.javacv.FrameRecorder.Exception {
recordCamera("rtmp://192.168.30.21/live/record1",25);
}
一帧一帧显示都没问题，就是没推到RTMP，请问是什么问题？
