I am trying to build an app which can process videos from disk. The JavaCV libraries provided the necessary tools for grabbing frames. For some reason, my program crashes when FrameGrabber.start() is invoked.
I'm not sure what I'm doing wrong, I'm new android programming. I've searched for similar cases. Haven't found one posted on the web yet which is similar to mine.
Any help would be greatly appreciated.
This is the code I've implemented.
package test.trackerproto;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import com.googlecode.javacv.FFmpegFrameGrabber;
import com.googlecode.javacv.Frame;
public class Saved_process extends ActionBarActivity {
String FilePath;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ffile);
// VideoView display = (VideoView)findViewById(R.id.videoView1);
Intent intent = getIntent();
FilePath = intent.getStringExtra("path");
FFmpegFrameGrabber vidcap;
// display.setVideoPath(FilePath);
vidcap = new FFmpegFrameGrabber(this.FilePath);
Log.i(camera.TAG, "Framegrab initiated");
Frame cur_frame = null;
try
{
vidcap.setFormat("mp4");
Log.i(camera.TAG, "Frame set");
vidcap.start();
} catch (com.googlecode.javacv.FrameGrabber.Exception e)
{
Log.e(camera.TAG, "Failed to start grabber" + e);
}
do
{
try
{
cur_frame = vidcap.grabFrame();
if(cur_frame != null){
Log.i(camera.TAG, "grab success");
}
} catch (com.googlecode.javacv.FrameGrabber.Exception e)
{
Log.e(camera.TAG, "video grabFrame failed: "+ e);
}
}while(cur_frame != null);
try
{
vidcap.stop();
}catch (com.googlecode.javacv.FrameGrabber.Exception e)
{
Log.e(camera.TAG, "failed to stop video grabber", e);
return;
}
}
}I've got no compile errors, when start() is invoked it fails, as the last log.i is "frame set"

The version of javacv used was 0.7 and this version had issues similar to this (from my understanding most versions below 0.10 had a similar issue). The latest version to as of the post date, is 0.11 and using this it solved my problems. I'm leaving this here, if in case it helps someone!
