使用Camera2的“ I / [MALI] [Gralloc]：lock_ycbcr：videobuffer_status无效，请使用默认值”垃圾邮件

Question

此处的相关代码：

private void setupCamera(int width, int height) {
    CameraManager cameraManager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
    try {
        CameraCharacteristics cameraCharacteristics = null;
        for (String cameraId : cameraManager.getCameraIdList()) {
            mCameraId = cameraId;
            cameraCharacteristics = cameraManager.getCameraCharacteristics(mCameraId);

            if (cameraCharacteristics.get(CameraCharacteristics.LENS_FACING) ==
                    CameraCharacteristics.LENS_FACING_BACK) {
                break;
            }
        }
        StreamConfigurationMap map = cameraCharacteristics.get(CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP);

        mImageSize = new Size(640, 480);
        mFrameDuration = map.getOutputMinFrameDuration(ImageFormat.YUV_420_888,mImageSize);
        mImageReader = ImageReader.newInstance(640,
                480,
                ImageFormat.YUV_420_888, 50);

        mSurface = mImageReader.getSurface();
        mImageReader.setOnImageAvailableListener(mOnImageAvailableListener, mImageReaderHandler);

使用Google的Camera2 API示例代码中的标准方法设置PreviewSize。

它在华硕Zenpad P028平板电脑（牛轧糖）上运行

一遍又一遍显示的日志：

 - I/[MALI][Gralloc]: lock_ycbcr: videobuffer_status is invalid, use default value

 - D/Surface: Surface::setBuffersUserDimensions(this=0x70ee1c7c00,w=640,h=480)

好像在来回重置缓冲区大小。可以预测地将帧速率降低到每帧60ms。

在我的Nexus 5P手机（棉花糖）上不会发生这种情况。

我尝试将mImageSize设置为不同的尺寸。
