Record video/audio on Android

Hi,

I have tried several different types of code to record video and audio on android.
I am using the UDOO dual with android 4.4 kitkat.

I try to use the MediaRecorder. But is does not seems to find a correct videoSource. When i try to set the videoSize or VideoEncoder or VideoFramerate the software crashes without usefull debug info. Even the try/catch block gives an empty exception.

I hope someone can help me

Thanks in advance,
Tom

 

Hi there TomImage+,
which camera are u using?
Cheers

 

Oh i forgot to mention it. how dumb of me,

I am using the MIPI 5MP AF Camera

 

A few questions then:
Do you have granted permission in you android manifest?

Code:

      <uses-permission android:name="android.permission.CAMERA" />
      <uses-feature android:name="android.hardware.camera" />

try to use something like this to get the camera preview, to check if it work

Code:

   public class MainActivity extends Activity implements TextureView.SurfaceTextureListener {

    private Camera mCamera;
    private Camera.CameraInfo info;
    private TextureView mTextureView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

        mTextureView = (TextureView) findViewById(R.id.camera_texture);
        mTextureView.setSurfaceTextureListener(this);
}


@Override
    public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {

    Log.i(DEBUG, "onSurfaceTextureAvailable");
        info = new Camera.CameraInfo();
        for (int i = 0; i < Camera.getNumberOfCameras(); i++) {
           Camera.getCameraInfo(i, info);

            Log.i(DEBUG, "info: "+ info.facing);

//mCamera = Camera.open(i);

      }


        //make portrait
        //mCamera.setDisplayOrientation(90);

try {
/* Tell the camera to write onto our textureView mTextureView */
mCamera.setPreviewTexture(surfaceTexture);
mCamera.startPreview();
} catch (IOException ioe) {
Log.e("camera-reverse", ioe.getMessage());
}

}

@Override
    public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) {
    Log.i(DEBUG, "onSurfaceTextureDestroyed");
        if (null != mCamera) {
            mCamera.stopPreview();
            mCamera.release();
        }
        return true;
    }

    @Override
    public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {
    //Log.i(DEBUG, "onSurfaceTextureUpdated");
    }
 
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture arg0, int arg1, int arg2) {
// TODO Auto-generated method stub
}

 

The indentation is not properly done, forgive me for that.

 

That is no problem.
i had the permissions in my app so that was not the issue
I do get the preview now! Thank you

How do i record the video now preferrably with the audio stream from the mic input

 

Never done this before, anyway it's standard Android programming.

 

Thank you very much!
