Apps Android Video Frame Retrieving

[baris3437]

Hi everyone!

I'm new in developing andorid apps. this semester, I'll do an app called video summarization on android platform. Unfortunately, I don't have enough knowledge to do it.

On android platform, is this possible? İf this is possible, how can I do this?
With my researches, I found informations below:

On android platform, video format is .mp4 . First, we have to retrieve frames from our .mp4 file. .Mp4 files are so complicated. This can be easy with using Opencv functions. but Opencv is written in C++. So I can't use OpenCv functions in my Java codes. But this can be possible with JNA and JAVACV.
Firstly, I set up Opencv in my computer. then I downloaded jna.jar and javacv.jar . and I imported these jars to Eclipse. I did some samples with using javacv methods. But I can't handle this. some errors occured. Here is my code:

package den;

import static name.audet.samuel.javacv.jna.cxcore.v21.*;
import static name.audet.samuel.javacv.jna.cv.v21.*;
import static name.audet.samuel.javacv.jna.highgui.v21.*;

public class Dene {
public static void main(String[] args) {
IplImage image = cvLoadImage("C:\\Users\\baris\\Desktop\\1.jpg", 1);
if (image == null) {
System.err.println("Could not load image file.");
} else {
cvSmooth(image, image, CV_GAUSSIAN, 3, 0, 0, 0);
cvSaveImage("C:\\Users\\baris\\Desktop\\2.jpg",image); // error occured in this code.
}
}
}

Here is the error:
#
# A fatal error has been detected by the Java Runtime Environment:

#
# If you would like to submit a bug report, please visit:

Anyway, if the way I followed is true, I'll follow this way and fix the errors. In contrast if not, please give me the right way to handle this project.
