I am using opencv abnd javafx. How to get frames of the video for image processing using opencv and java
I am working on the same project: So, here is my working code. Set the environmental variable first.
public class VideoCap {
public static void main (String args[]){
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
VideoCapture cap =new VideoCapture();
cap.set(Videoio.CV_CAP_PROP_FRAME_HEIGHT,768 );
cap.set(Videoio.CV_CAP_PROP_FRAME_WIDTH,1024);
cap.open("C:\\Users\\Admin\\Downloads\\Video\\Pakistananthem.mp4");
//cap.open(0);
Mat pic = new Mat();
if (cap.isOpened())
{
System.out.println("Video is opened");
//If you want to get the total number of frames in a video just uncomment this
//int length = (int) cap.get(Videoio.CAP_PROP_FRAME_COUNT);
//System.out.println(length);
cap.read(pic);
Imgcodecs.imwrite("C:\\Users\\Admin\\Desktop\\pics\\pics.png", pic);
cap.release();
}
else
{
System.out.println("Fail");
}
}
}
