            mRecorder.setOutputFile(viodFile.getAbsolutePath());  
            // 指定SurfaceView來預覽視頻  
            mRecorder.setPreviewDisplay(sView.getHolder().getSurface());  
            mRecorder.prepare();  
            
 
// 開始錄制

//mRecorder.setVideoSize(320, 280);  
// mRecorder.setVideoFrameRate(5);
