錯誤=從qubuf無效的參數是什麼意思

我想知道什麼錯誤=從qubuf無效的參數是什麼意思

Error = Invalid argument from qbuf

手段。

發生這種情況時，我按下我的視頻播放器上的主頁按鈕。這是一些新的東西，或者讓其他人看過類似的東西。

我無法對谷歌發現什麼特別的標籤v412_utils

這顯示了Nexus S的設備上

的的onPause菜單

protected void onPause() 

{ 

    Log.i("VideoPlayer", "onPauseCalled"); 
    super.onPause(); 

    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); 
    surfaceCreated = false; 
    focusFirst = false; 
    if(!pm.isScreenOn()) 
    { 
     pauseMedia(); 
     Log.i("onPause", " save states to be called"); 
     if(saveAllowed) 
      saveStates(); 
     view.setVisibility(View.GONE); 
     //Log.i("onPause", "visibility GOne"); 
     removeListeners(); 
     doCleanUp(); 
    } 

}

就像我說的那樣，只有當我按回家時纔會發生噸。屏幕關閉和其他情況下工作。只需在Home Button上獲得即可。

我在不同的上下文中有同樣的錯誤，我找不到解決方案，但只是請注意它不是412，它是v4l2_utils， 4L2 – Vlad

什麼是上下文。但我注意到，當我得到這個qbuff錯誤時，它是因爲我正在做一些表面視圖（使用pushbuffers）而不是銷燬它（destroy的表面視圖從未被調用，因此它的緩衝區有問題）。至少這是我發現的。 – Raigex

在我的情況下，這是因爲我想縮小SurfaceView到2x2 px ..和低級別的lib無法弄清楚如何正確繪製相機預覽..但你是對的，它必須與SurfaceView .. – Vlad

我找到了我認爲的答案。因爲我不會在轉到其他活動時暫停我的媒體或移除我的Surface View。我認爲它onResume（）失敗。我允許它暫停媒體，並設置可見性以下午以外是屏幕上，它停止給我那個錯誤
