當我停止錄製時MediaRecorder失敗

我有這個錯誤。有人可以幫助我，我認爲這是關於觸摸聽衆的事情...當我釋放我的手指時，錯誤正在發生。當我停止錄製時MediaRecorder失敗

當我嘗試運行這段代碼中正在發生的事情：從觸摸聽者

：

/// Preview is SurfaceView in my view 
preview.setOnTouchListener(new View.OnTouchListener() { 

     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      switch (event.getAction()) { 
      case MotionEvent.ACTION_DOWN: 

       prepareRecording(); 
       break; 
      case MotionEvent.ACTION_MOVE: 
      //Log.d(TAG, String.format("ACTION_MOVE | x:%s y:%s", 
       break; 
      case MotionEvent.ACTION_UP: 
       stopRecording(); 
       break; 
      } 
      return true; 
     } 
    });

這兩種方法：

private void prepareRecording() { 
    try { 
     camera.unlock(); 

     recorder = new MediaRecorder(); 
     recorder.setCamera(camera); 
     recorder.setAudioSource(MediaRecorder.AudioSource.MIC); 
     recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); 
     recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); 

     File tempFile = new File(Environment.getExternalStorageDirectory(), "/rec/temp/video_" + String.valueOf(videoCount) + ".mp4"); 

     recorder.setOutputFile(tempFile.getPath()); 
     recorder.setVideoFrameRate(25); 
     recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT); 
     recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT); 
     recorder.setPreviewDisplay(holder.getSurface()); 

     recorder.prepare(); 
     recorder.start(); 
    } catch (IllegalStateException e) { 
     Log.e("REDORDING :: ",e.getMessage()); 
     e.printStackTrace(); 
    } catch (IOException e) { 
     Log.e("REDORDING :: ",e.getMessage()); 
     e.printStackTrace(); 
    } 
} 

private void stopRecording() { 
    recorder.stop(); 
    camera.lock(); 
}

看那documentation ：

請注意，如果在調用 stop（）時沒有收到有效的音頻/視頻數據，則會故意將RuntimeException拋出到應用程序。如果在 start（）後立即調用stop（），則會發生這種情況。由於輸出文件在發生這種情況時沒有正確構建，故障使應用程序可以相應地採取措施清理輸出文件（例如，刪除輸出文件）。

換句話說：Dalvik故意拋出異常。你必須處理它來清理你的應用程序後。你不得不處理這樣的：

private void stopRecording() { 
    try{ 
     recorder.stop(); 
    }catch(RuntimeException stopException){ 
     //handle cleanup here 
    } 
    camera.lock(); 
}

有沒有其他方法可以做到這一點？ – 2016-01-07 07:34:48

在我的情況下，它不是立即開始/停止，或mediarecorder mediaprojection只是不工作？ https://stackoverflow.com/a/34986043/4548520我不明白爲什麼這個問題發生時，我停止屏幕錄製 – user25 2017-07-29 20:12:15

我有一個類似的錯誤-1007當我錄製的音頻與AMR_WB，但事實證明，問題是，我忘了設定的採樣率。

mediaRecorder.setAudioSamplingRate(16000);
