MediaRecorderでの録画が動作しない

MediaRecorderクラスを使用してビデオを録画しようとしていますが、多くの例を試しましたが、すべて同じ問題があり、数秒間録画してから、第二に、これは数回起こり、その後のプレビューは完全に立ち往生し、私は次の出力を得る：これは、この問題が発生した活動であるMediaRecorderでの録画が動作しない

：

public class MainActivity extends Activity implements View.OnClickListener, SurfaceHolder.Callback { 
    MediaRecorder recorder; 
    SurfaceHolder holder; 
    boolean recording = false; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

     recorder = new MediaRecorder(); 
     initRecorder(); 
     setContentView(R.layout.activity_main); 

     SurfaceView cameraView = (SurfaceView) findViewById(R.id.cameraView); 
     holder = cameraView.getHolder(); 
     holder.addCallback(this); 
     holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 

     cameraView.setClickable(true); 
     cameraView.setOnClickListener(this); 
    } 

    private void initRecorder() { 
     recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); 
     recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); 

     CamcorderProfile cpHigh = CamcorderProfile 
       .get(CamcorderProfile.QUALITY_HIGH); 
     recorder.setProfile(cpHigh); 
     recorder.setOutputFile("/sdcard/videocapture_example.mp4"); 
     recorder.setMaxDuration(50000); // 50 seconds 
     recorder.setMaxFileSize(5000000); // Approximately 5 megabytes 
    } 

    private void prepareRecorder() { 
     recorder.setPreviewDisplay(holder.getSurface()); 

     try { 
      recorder.prepare(); 
     } catch (IllegalStateException e) { 
      e.printStackTrace(); 
      finish(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
      finish(); 
     } 
    } 

    public void onClick(View v) { 
     if (recording) { 
      recorder.stop(); 
      recording = false; 

      // Let's initRecorder so we can record again 
      initRecorder(); 
      prepareRecorder(); 
     } else { 
      recording = true; 
      recorder.start(); 
     } 
    } 

    public void surfaceCreated(SurfaceHolder holder) { 
     prepareRecorder(); 
    } 

    public void surfaceChanged(SurfaceHolder holder, int format, int width, 
           int height) { 
    } 

    public void surfaceDestroyed(SurfaceHolder holder) { 
     if (recording) { 
      recorder.stop(); 
      recording = false; 
     } 
     recorder.release(); 
     finish(); 
    } 
}

をそして、これはレイアウトですファイル：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 

    <SurfaceView 
     android:id="@+id/cameraView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 
</LinearLayout>

EDIT：

私も、このアプリケーションによって作成されたファイルを開くことができません（ただし、彼らはデータが含まれています）。あなたがここを見てしたいと思うかもしれ
