Hello,I have a problem: load a file video from path with openCV; with webcam all right..with path bad ...don't work ;( this is my code: help me... premetto che con lacquisizione video non ho nessun problema, il problema si pone quando devo caricare un video da locale...ecco il codice

import org.opencv.core.*; import org.opencv.highgui.Highgui; import org.opencv.highgui.VideoCapture;

public class VideoCaptureFile {

public static void main (String args[]){

System.loadLibrary(Core.NATIVE_LIBRARY_NAME); VideoCapture camera = new VideoCapture("C://video.avi");

if(!camera.isOpened()){ System.out.println("Error"); }

Mat frame = new Mat(); while(true){ if (camera.read(frame)){ System.out.println("Frame Obtained"); System.out.println("Captured Frame Width " + frame.width() + " Height " + frame.height()); Highgui.imwrite("camera.jpg", frame);
System.out.println("OK"); break; } } camera.release(); } }

OUTPUT :error
