Problème avec l'enregistrement vidéo après mise au point automatique dans Android

Question

En essayant de créer une application qui essaie de faire la mise au point automatique de la caméra avant de commencer l'enregistrement vidéo. Directement en utilisant MediaRecorder ne fait pas la mise au point automatique de l'appareil photo. Pour cela, j'utilise Camera et en utilisant le rappel, je peux l'autofocus. Mais fournir cette instance au MediaRecorder me pose beaucoup de problèmes. Voici le code im en utilisant pour l'enregistrement

public boolean startRecording() 
{ 
    try 
    { 
     mCamera.unlock(); 

     mediaRecorder = new MediaRecorder(); 
     mediaRecorder.setCamera(mCamera); 

     mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); 
     mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); 

     CamcorderProfile profile = CamcorderProfile 
       .get(CamcorderProfile.QUALITY_LOW); 
     mediaRecorder.setProfile(profile); 

     mediaRecorder.setMaxDuration(maxDurationInMs); 

     File file = new File(outputFile); 
     if (file.exists()) 
      file.delete(); 
     file = new File(outputFile); 

     try 
     { 
      file.createNewFile(); 
     } 
     catch (IOException e1) 
     { 
      // TODO Auto-generated catch block 
      e1.printStackTrace(); 
      Log.e("Deepak", "*** first catch ***"); 
     } 


     mediaRecorder.setOutputFile(outputFile); 
     mediaRecorder.setPreviewDisplay(mHolder.getSurface()); 

     mediaRecorder.setMaxFileSize(maxFileSizeInBytes); 

     mediaRecorder.prepare(); 
     mediaRecorder.start(); 

     return true; 
    } 
    catch (IllegalStateException e) 
    { 
     Log.e(TAG, e.getMessage()); 
     e.printStackTrace(); 
     return false; 
    } 
    catch (IOException e) 
    { 
     Log.e(TAG, e.getMessage()); 
     e.printStackTrace(); 
     return false; 
    } 
} 

Les attributs de l'appareil photo sont les suivantes:

Camera.Parameters parameters = mCamera.getParameters(); 
    List<Size> sizeList = parameters.getSupportedPreviewSizes(); 
    parameters.setPreviewFormat(ImageFormat.JPEG); 
    parameters 
      .setPreviewSize(sizeList.get(0).width, sizeList.get(0).height); 
    mCamera.setParameters(parameters); 
    mCamera.startPreview(); 

Tout cela me donne le message d'erreur suivant:

Cela crée un fichier sur l'emplacement spécifié qui est totalement obscurci, juste un tas de lignes horizontales vertes.

Toutes les autorisations sont placées. En utilisant Android 2.2. Essayé le code exact que this mais se est similaire VENC_ERROR

Answer 1

Vous devez arrêter l'aperçu avant déverrouiller la caméra

mCamera.stopPreview(); 

mCamera.unlock();
