Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. grabber.start();
2.
3.

What is the expected output? What do you see instead?
I want to record a video, but I can't even start the grabber

What version of the product are you using? On what operating system?
I am working on Android. 
I have these jars:
  - ffmpeg 2.2.1-0.8.jar
  - javacpp
  - javacv
  - opencv

I tired to add every jar from here: 
http://search.maven.org/#search%7Cga%7C1%7Cbytedeco
But it didn't change anything.

Please provide any additional information below.

//////////////////////////// CODE //////////////////////////////
Here is the code I launch:

public void record(){
        try {
            OpenCVFrameGrabber grabber = new OpenCVFrameGrabber(0);
            Log.d("GRABBER", grabber.toString());

            grabber.start();

        } catch (Exception e) {
            Log.d("GRABBER", e.toString());
            e.printStackTrace();
        }

    }
