Question

public class FulfillVideoTaskActivity extends Activity implements SurfaceHolder.Callback, OnInfoListener, OnErrorListener{

private Button initBtn = null;
private Bu         


        

Answer 1

Try this code

first

   setRecorder() ;
   SurfaceView  videoShootSurfaceView = (SurfaceView) findViewById(R.id.shootVideosurfaceView_VSD);


    SurfaceHolder videoSurfaceHolder = videoShootSurfaceView.getHolder();
    videoSurfaceHolder.addCallback(this);
    videoSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

set the recorder type

    public void setRecorder() {
    recorder = new MediaRecorder();
    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
    // recorder.setVideoSize(640, 480);
    recorder.setVideoSize(320, 240);
    // recorder.setVideoSize(480, 320);
    // recorder.setVideoSize(176, 144);
    recorder.setVideoFrameRate(15);
    // recorder.setMaxDuration(3600000);
    recorder.setMaxDuration(300000);
    recorder.setOutputFile("/sdcard/videocapture_example.mp4");
}

override this methhod.

    @Override
public void surfaceCreated(SurfaceHolder holder) {
    camera = Camera.open();
    recorder.setPreviewDisplay(holder.getSurface());
    if (recorder != null) {
        try {
            recorder.prepare();
        } catch (IllegalStateException e) {
            Log.e("IllegalStateException", e.toString());
        } catch (IOException e) {
            Log.e("IOException", e.toString());
        }
    }
}

To start the recording

    public void startRecording() {
    setRecorder();
    recorder.setPreviewDisplay(recoderTempHolder.getSurface());
    if (recorder != null) {
        try {
            recorder.prepare();
            recorder.start();
        } catch (IllegalStateException e) {
            Log.e("IllegalStateException", e.toString());
        } catch (IOException e) {
            Log.e("IOException", e.toString());
        }
    }

}

To stop the recording

  public void stopRecording() {

    recorder.stop();
    // recorder.reset();
    recorder.release();

}
