  • Issue in CV_FOURCC('H', '2', '6', '4')

    16 décembre 2014, par Ashwin

    I am trying to use H264 encoding type for compressing the live streaming from Camera (which is supporting the H264 codec) am getting below -
    [I am using OPENCV 3.0 beta version (latest)in windows 7 64 bit system .My camera is also supporting H264 codec (find more details below) ]
    My ffmpeg code got built with h264 lib :
    This build was compiled with the following external libraries :
    x264 20140826-git-dd79a61 http://videolan.org/developers/x264.html

    **error :**
    

    
Frame size = 1280x720
    
Could not find encoder for codec id 28: Encoder not foundERROR: Failed to write the video
    
Press any key to continue . . .

    Below is my code :

    int main(int argc, char *argv[])
    
{
    
 // QApplication a(argc, argv);
    

    
  VideoCapture cap(0); //capture webcam
    

    
  if (!cap.isOpened()) //if not successful then exit
    
  {
    
    cout << "Cannot open webcam";
    
    return -1;
    
  }
    

    
  namedWindow("Camera feed", 1); //create window
    

    
  cap.set(3, 1280);
    
  cap.set(4, 720);
    

    
  double dWidth  = cap.get(CV_CAP_PROP_FRAME_WIDTH); //get width of frames of video
    
  double dHeight = cap.get(CV_CAP_PROP_FRAME_HEIGHT); //get height of frames of video    
    

    

    
  Size frameSize(static_cast<int>(dWidth), static_cast<int>(dHeight));
    

    
  cout &lt;&lt; "Frame size = " &lt;&lt; dWidth &lt;&lt; "x" &lt;&lt; dHeight &lt;&lt; endl;
    

    
  VideoWriter oVideoWriter("video.avi", CV_FOURCC('X', '2', '6', '4'), 30, frameSize);
    

    
  if(!oVideoWriter.isOpened())
    
  {
    
    cout &lt;&lt; "ERROR: Failed to write the video" &lt;&lt; endl;
    
    return -1;
    
  }
    
  while(1)
    
  {
    
    Mat frame;
    
    bool bSuccess = cap.read(frame); //read a new frame from video
    

    
    if(!bSuccess) //if unsuccessful, break loop
    
    {
    
        cout &lt;&lt; "Cannot read frame from video file" &lt;&lt; endl;
    
        break;
    
    }
    

    
    oVideoWriter.write(frame); //write the frame into the file
    
    imshow("Camera feed", frame); //show the frame in "Live Feed" window
    

    
    cout &lt;&lt; "Recording" &lt;&lt; endl;
    

    
    if (waitKey(30) == 27)
    

    
    {
    
      cout&lt;&lt; "Esc key is pressed by user" &lt;&lt; endl;
    
      break;
    
    }
    

    
  }
    
  return 0;
    
}
    
</int></int>

    Here is the proof that my camera is supporting the H264 :
