问题描述

所以我试图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);

调试期间,FileMi具有以下值:文件:///mnt/sdcard/spootur/videos/c14e0eb2-0737-4931-9898-4931-9898-4931-9898-4931-9898- 4931-9898- 4931-9898- 4931-9898- 4931-9898- 4931-9898- 4931-9898-E85D10BAB74E.MP4和videointent具有mextras值:

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,它变得很好,但是当我重新点击记录按钮停止录制时,相机应用程序抛出这个:

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)

任何可能导致这个的想法以及如何解决它?谢谢!

还:我可以确认录制的视频文件位于该URI.

推荐答案

实际上,我发现在某些情况下MediaStore.EXTRA_OUTPUT不正常工作, 因此,其他特技方式是,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
         }
    }
 }

尝试上面的代码,让我知道你的成功.

问题描述

So I'm trying to use the built in camera activity to record a video using the below code:

    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);

During debugging, fileURI has a value of: file:///mnt/sdcard/Spootur/Videos/c14e0eb2-0737-4931-9898-e85d10bab74e.mp4, and videoIntent has an mExtras value of:

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

When I start recording, it goes fine, but when I reclick the record button to stop recording, the camera app throws this:

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.CamcorderEngine.doStopVideoRecordingSync(CamcorderEngine.java:849)
05-11 01:08:11.325: E/AndroidRuntime(3748):     at com.sec.android.app.camera.CeStateRecording.handleRequest(CeStateRecording.java:69)
05-11 01:08:11.325: E/AndroidRuntime(3748):     at com.sec.android.app.camera.CeRequestQueue.startFirstRequest(CeRequestQueue.java:123)
05-11 01:08:11.325: E/AndroidRuntime(3748):     at com.sec.android.app.camera.CeRequestQueue.access$200(CeRequestQueue.java:32)
05-11 01:08:11.325: E/AndroidRuntime(3748):     at com.sec.android.app.camera.CeRequestQueue$MainHandler.handleMessage(CeRequestQueue.java:60)

Any ideas of what could be causing this and how to fix it? Thanks!

Also: I can confirm that the recorded video file is at that URI.

推荐答案

Actually, I found in some case MediaStore.EXTRA_OUTPUT doesn't work properly, SO the other trick way is, store your captured video file in 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
         }
    }
 }

Try the above code and let me know about your success.
