我正在使用openCV从摄像机捕获视频并将其存储到avi文件，问题是当我完成捕获并运行avi文件时，视频流看起来笨拙地...

这是代码

int isColor = 1;
 int frameW  = 640;
 int frameH  = 480;
 int fps     = 25;

 CvCapture* capture = cvCaptureFromCAM(0);
 assert( capture != NULL );

 cvNamedWindow( "Webcam", CV_WINDOW_AUTOSIZE);

 CvVideoWriter *writer = cvCreateVideoWriter(
   "out.avi",
   CV_FOURCC('M','J','P','G'),
   fps,
   cvSize(frameW,frameH),
   isColor
  );

 IplImage* frame = cvQueryFrame( capture );

 while( (frame = cvQueryFrame( capture )) != NULL ) {
  cvWriteFrame(writer, frame);
  cvShowImage("Webcam", frame);
  char c = cvWaitKey( 33 );
  if ( c == 27 ) break;
 }

最佳答案

cvSetCaptureProperty和cvGetCaptureProperty并不总是有效。另外，您是否尝试过fps = 30？

还值得注意的是，您需要以与捕获fps相同的fps播放视频。
