所以我正在尝试使用内置的相机活动来使用以下代码录制视频：

    Intent videoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    videoIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileURI);
    videoIntent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 60);
    startActivityForResult(videoIntent, VIDEO_ACTIVITY);

调试时fileURI的值为：file:///mnt/sdcard/Spootur/Videos/c14e0eb2-0737-4931-9898-e85d10bab74e.mp4，videoIntent的mExtras值为：

Bundle[{output=file:///mnt/sdcard/Spootur/Videos/c14e0eb2-0737-4931-9898-e85d10bab74e.mp4, android.intent.extra.durationLimit=60}]

当我开始录制时，一切正常，但是当我重新单击录制按钮停止录制时，相机应用程序会抛出这个：

05-11 01:08:11.325: E/AndroidRuntime(3748):     at com.sec.android.app.camera.CamcorderEngine.renameTempFile(CamcorderEngine.java:1352)

05-11 01:08:11.325: E/AndroidRuntime(3748):     at com.sec.android.app.camera.CeRequestQueue$MainHandler.handleMessage(CeRequestQueue.java:60)

关于可能导致此问题以及如何解决的任何想法？谢谢！

另外：我可以确认录制的视频文件位于该 URI。

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
         }
    }
 }

试试上面的代码，让我知道你的成功。
