Question

我一直在尝试创建一个记录视频并将视频上传到S3存储桶的应用。我一直在使用（稍微改变一下）Android capture video intent article。但是当录音结束时，我会得到一个错误列表。（我正在使用Galaxy S2手机，所以支持它。）

CameraActivity代码：

        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输出：

Answer 1

好友你应该看到以下问题的答案，它对我有用，绝对适合你。

Android: Video Recording Throws Error

注意：我有如下错误

at com.sec.android.app.camera.CamcorderEngine.renameTempFile（CamcorderEngine.java:1206）

解决方案：在Android 2.2,2.3中工作 ... 我已经完成了以下捕捉照片的过程

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

好的，我改进了Logcat以查看错误的开始位置，以及程序失败的第一行：

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

Google快速搜索将我带到了this place，显然MediaStore.EXTRA_OUTPUT 没有正常工作且存在问题。

这就是那里写的答案：

实际上，我发现在某些情况下MediaStore.EXTRA_OUTPUT无法正常工作，所以另一种技巧方式是，将捕获的视频文件存储在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
        }
   }
}

尝试录制视频时出现VerifiyAndSetParameter错误
