MediaRecorder сохраняет видео того же размера, что и SurfaceView

Question

привет Я пытаюсь реализовать запись в своем приложении. Я могу записывать видео и сохранять его, но темп и разрешение на аспект полностью перепутаны. Как я могу зарегистрироваться для регистрации с самым высоким качеством?

Это мой код

public class VideoFragment extends Fragment implements SurfaceHolder.Callback{ 
    private ToggleButton mToggleButton; 
    private SurfaceHolder mHolder; 
    private SurfaceView mSurfaceView; 
    private MediaRecorder mMediaRecorder; 
    private Camera mCamera; 
    private boolean mInitSuccesful; 

    public static VideoFragment newInstance() { 
     Bundle args = new Bundle(); 
     VideoFragment fragment = new VideoFragment(); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    public VideoFragment(){} 

    @Override 
    public void onStart() { 
     super.onStart(); 
     getActivity().setTitle(R.string.video); 
    } 

    @Override 
    public void onResume() { 
     super.onResume(); 


    } 

    @Override 
    public void onPause() { 
     super.onPause(); 
     shutdown(); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     View rootView = inflater.inflate(R.layout.fragment_content, container, false); 

     Button yo = (Button) rootView.findViewById(R.id.pic); 
     yo.setVisibility(View.GONE); 


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

     mToggleButton = (ToggleButton) rootView.findViewById(R.id.toggleRecordingButton); 
     mToggleButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      // toggle video recording 
      public void onClick(View v) { 

       if (((ToggleButton)v).isChecked()) 
        if(mMediaRecorder == null) { 
         try { 
          initRecorder(mHolder.getSurface()); 
         } catch (IOException e) { 
          e.printStackTrace(); 
         } 
        }else{ 
         try { 
          mMediaRecorder.start(); 
         }catch (NullPointerException e){ 
          e.printStackTrace(); 
          try { 
           initRecorder(mHolder.getSurface()); 
          } catch (IOException ex) { 
           ex.printStackTrace(); 
          } 
         } 
        } 
       else { 
        mMediaRecorder.stop(); 
        mMediaRecorder.reset(); 
        try { 
         initRecorder(mHolder.getSurface()); 
        } catch (IOException e) { 
         e.printStackTrace(); 
        } 
       } 


      } 
     }); 

     return rootView; 
    } 

    /* Init the MediaRecorder, the order the methods are called is vital to 
    * its correct functioning. 
    */ 
    private void initRecorder(Surface surface) throws IOException { 
     // It is very important to unlock the camera before doing setCamera 
     // or it will results in a black preview 
     if(mCamera == null) { 
      mCamera = Camera.open(); 
      mCamera.unlock(); 
     } 

     if(mMediaRecorder == null) 
      mMediaRecorder = new MediaRecorder(); 

     mMediaRecorder.setPreviewDisplay(surface); 
     mMediaRecorder.setCamera(mCamera); 

     mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); 
     mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT); 
     File file = new File(Environment 
       .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), 
       Utils.getVideoFilename()); 
     // "touch" the file 
     if(!file.exists()) { 
      File parent = file.getParentFile(); 
      if(parent != null) 
       if(!parent.exists()) 
        if(!parent.mkdirs()) 
         throw new IOException("Cannot create " + 
           "parent directories for file: " + file); 

      file.createNewFile(); 
     } 

     mMediaRecorder.setOutputFile(file.getAbsolutePath()); 

     // No limit. Don't forget to check the space on disk. 
     mMediaRecorder.setMaxDuration(-1); 
     mMediaRecorder.setVideoFrameRate(15); 

     mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT); 

     try { 
      mMediaRecorder.prepare(); 
     } catch (IllegalStateException e) { 
      // This is thrown if the previous calls are not called with the 
      // proper order 
      e.printStackTrace(); 
     } 

     mInitSuccesful = true; 
    } 

    @Override 
    public void surfaceCreated(SurfaceHolder holder) { 
     try { 
      if(!mInitSuccesful) 
       initRecorder(mHolder.getSurface()); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 

    @Override 
    public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) { 

    } 

    @Override 
    public void surfaceDestroyed(SurfaceHolder holder) { 
     shutdown(); 
    } 



    private void shutdown() { 
     // Release MediaRecorder and especially the Camera as it's a shared 
     // object that can be used by other applications 
     mMediaRecorder.reset(); 
     mMediaRecorder.release(); 
     mCamera.release(); 

     // once the objects have been released they can't be reused 
     mMediaRecorder = null; 
     mCamera = null; 
    } 
} 

Благодаря

EDIT: Решение благодаря принятому ответу

CamcorderProfile cpHigh = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH); 
mMediaRecorder.setProfile(cpHigh); 

Answer 1

Попробуйте использовать CamcorderProfile установить все разрешения и качества MediaRecorder сначала настройки; вы в настоящее время не устанавливаете многие из значений, например размер. MediaRecorder не будет обращать внимания на размеры вашего SurfaceView, для одного.
