嘗試錄製視頻時出現VerifiyAndSetParameter錯誤

Question

我一直在嘗試創建一個應用程序，用於將視頻記錄並上傳到S3存儲桶。 我一直在使用（有點改變）Android capture video intent article。但是當錄音結束時，我會收到錯誤列表。 （我使用的是Galaxy S2手機，因此支持）。

代碼CameraActivity：

 Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); 
     fileUri = SavingMedia 
       .getOutputMediaFileUri(SavingMedia.MEDIA_TYPE_VIDEO); 
     path = fileUri.toString(); 

     intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 30); 
     intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); 
     intent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION, 
       ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
     intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0.2); 

     startActivityForResult(intent, CAPTURE_VIDEO_REQUEST_CODE); 

logcat的輸出：

Answer 1

哥們你應該看到以下問題， 它正在爲我和你肯定工作的答案。

Android: Video Recording Throws Error

注：我有同樣的錯誤在com.sec.android.app.camera.CamcorderEngine.renameTempFile（CamcorderEngine.java:1206）

解決方案如下

：在工作Android 2.2系統，2.3 ... 我已經做了以下過程拍攝照片

int CAMERA_WITH_VIDEO_DATA = 2; 
//start photo capture activity... 

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE, null); 
startActivityForResult(intent, CAMERA_WITH_VIDEO_DATA); 

.... 
.... 

private void saveVideoFileOnActivityResult(Intent videoIntent){ 
    FileInputStream fis = null; 
    FileOutputStream fos = null; 
    File mCurrentVideoFile = null; 
    try { 
     mCurrentVideoFile = new File("path_to_your_file"); 
     AssetFileDescriptor videoAsset = getContentResolver().openAssetFileDescriptor(videoIntent.getData(), "r"); 
     fis = videoAsset.createInputStream(); 
     //File videoFile = new File(Environment.getExternalStorageDirectory(),"<VideoFileName>.mp4"); 
     fos = new FileOutputStream(mCurrentVideoFile); 

     byte[] buffer = new byte[1024]; 
     int length; 
     while ((length = fis.read(buffer)) > 0) { 
       fos.write(buffer, 0, length); 
      }  
     //fis.close(); 
     //fos.close(); 
    } catch (IOException e) { 
     // TODO: handle error 
    e.printStackTrace(); 
    }finally{ 
     try { 
      if(fis!=null) 
       fis.close(); 
      if(fos!=null) 
       fos.close(); 
     } catch (Exception e2) { 
     // TODO: handle exception 
     e2.printStackTrace(); 
     } 
    } 
    } 
.... 
.... 

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
switch (requestCode) { 
case CAMERA_WITH_VIDEO_DATA: 
//pass data to above method to save it. 
saveVideoFileOnActivityResult(data); 
break; 

default: 
break; 
} 
} 

Answer 2

OK，我改進我的logcat看到錯誤開始的地方，並在其中的程序失敗，第一行是：

05-08 10:46:33.740: E/AndroidRuntime(29786): at com.sec.android.app.camera.CamcorderEngine.renameTempFile(CamcorderEngine.java:1206) 

快速谷歌搜索帶我到this place，顯然，MediaStore.EXTRA_OUTPUT正確不DOES工作並有問題。

這是一個寫有答案：

其實，我在一些情況下MediaStore.EXTRA_OUTPUT不能正常工作發現，讓對方招的辦法是，存儲捕獲的視頻文件在onActivityResult（ ）

protected void onActivityResult(int requestCode, int resultCode, Intent intent) { 
    super.onActivityResult(requestCode, resultCode, intent); 

    if (resultCode == RESULT_OK) { 
     try { 
      AssetFileDescriptor videoAsset = getContentResolver().openAssetFileDescriptor(intent.getData(), "r"); 
      FileInputStream fis = videoAsset.createInputStream(); 
      File videoFile = new File(Environment.getExternalStorageDirectory(),"<VideoFileName>.mp4"); 
      FileOutputStream fos = new FileOutputStream(videoFile); 

      byte[] buffer = new byte[1024]; 
      int length; 
      while ((length = fis.read(buffer)) > 0) { 
      fos.write(buffer, 0, length); 
     }  
     fis.close(); 
     fos.close(); 
     } catch (IOException e) { 
      // TODO: handle error 
     } 
    } 
}
