频繁开关摄像头cameraservice异常

xiaocai

压力测试频繁开关摄像头，在最后crash在设置参数的位置上
代码如下：
mCameraId = Integer.parseInt(target);
            mCamera = Camera.open(mCameraId);
            mCamera.setErrorCallback(mErrorCallback);
            Camera.Parameters param = mCamera.getParameters();
            param.setPreviewSize(PICTURE_WIDTH, PICTURE_HEIGHT);
            mCamera.setParameters(param);
日志如下：
开启前已经关闭摄像头了

频繁开关，压力测试运行5-6小时之后会出现此问题
