i using opencv 3.0.0 beta, , fails recognize cv::fourcc, cv_cap_prop_frame_width , cv_cap_prop_frame_height older versions. how go using them in newest version. here's sample code providing example of might need them, , unable use them in opencv 3.0.0 beta.

#include <opencv2/imgproc/imgproc.hpp> #include <opencv2/videoio/videoio.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/video/video.hpp> #include <opencv2/imgcodecs/imgcodecs.hpp> #include <opencv2/features2d/features2d.hpp> #include <opencv2/core.hpp>  #include <iostream> #include <sstream>  using namespace cv; using namespace std;  int main() { videocapture cap("h:\\images\\v1.mp4"); cv::videowriter writer; string filename = "h:\output_video.avi"; int fcc = cv::fourcc('d', 'i', 'v', '3'); // error shown line int fps = 20; cv::size framesize(cap.get(cv_cap_prop_frame_width),  cap.get(cv_cap_prop_frame_height)); // error shown line writer = videowriter(filename, fcc, fps, framesize);  for(;;) {     mat frame;     cap >> frame;     writer.write(frame);     namedwindow("output video");     imshow("output video", frame);     char key = (char)waitkey(50);     if(key == 'q' || key == 'q' || key == 27)     {         break;     } }  return 0; }
