i want to convert the sdcard images into video in android.After many of searching i found it is possible in javacv.when i try simple javacv sample in pure java,its working perfectly in my eclipse.but when i turn into android,the same sample does not run in android.i download and add all the .jar files and .so files in myproject->libs/armeabi folder.my project doesn't show any errors.but error occcured during the runtime.
i try with this class,
package com.example.ndkfoo_sample;
import static com.googlecode.javacv.cpp.opencv_core.cvReleaseImage;
import static com.googlecode.javacv.cpp.opencv_highgui.cvLoadImage;
import static com.googlecode.javacv.cpp.opencv_highgui.cvShowImage;
import static com.googlecode.javacv.cpp.opencv_highgui.cvWaitKey;
import static com.googlecode.javacv.cpp.opencv_imgproc.CV_GAUSSIAN;
import static com.googlecode.javacv.cpp.opencv_imgproc.cvSmooth;
import com.googlecode.javacv.cpp.opencv_core.IplImage;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
// @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IplImage img=cvLoadImage("helloworld.jpg");
cvShowImage("/mnt/sdcard/helloworld",img);
cvSmooth(img,img,CV_GAUSSIAN,13);
cvShowImage("Blur-Image",img);
cvWaitKey();
cvReleaseImage(img);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
My error is like as,
opencv error unspecified error.
My question is how to integrate opencv/javacv in android.is there any steps or tutorials.?
thanks,
Use the following lines .
**
opencv_core.IplImage img = cvLoadImage("/sdcard/folder/img1.jpg");
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("/sdcard/folder/test.mpeg",200,150);
try {
recorder.setCodecID( CODEC_ID_MPEG1VIDEO);
recorder.setFrameRate(30);
recorder.setPixelFormat( PIX_FMT_YUV420P);
recorder.start();
for (int i=0;i<100;i++)
{
recorder.record(image[x]);
}
recorder.stop();
}
catch (Exception e){
e.printStackTrace();
}
** This is supported by javacv library. for more details read Javacv Readme.txt file. Hope this will help you.
