无法在已部署版本中设置 Vuforia 帧格式

Question

我正在开发一个 AR-App，使用 Vuforia 作为模型目标，Zxing 作为 QR 码扫描。
我已经按照 Vuforia 页面上的描述设置了项目。当我处于播放模式时，一切正常，但一旦我构建它，尽管构建时没有编译错误，但它无法设置帧格式。

我正在使用：

统一 2018.4.8f1
Vuforia 8.3.8
.Net 4.7

我尝试了不同的帧格式，授予了统一管理员权限，关闭了病毒扫描程序

        private IEnumerator camInitializing()
        {
            //Wait for vuforia to initialize
            yield return new WaitForSeconds(4);
            if (CameraDevice.Instance == null)
            {
                Debug.LogError("No Instance of Camera could be found");
            }
            Debug.LogError( CameraDevice.Instance.IsActive());

            availableFormat = PIXEL_FORMAT.RGBA8888;
            if (!CameraDevice.Instance.SetFrameFormat(PIXEL_FORMAT.RGBA8888,true))
            {
                availableFormat = PIXEL_FORMAT.RGB888;
                if (!CameraDevice.Instance.SetFrameFormat(PIXEL_FORMAT.RGB888,true))
                {
                    availableFormat = PIXEL_FORMAT.RGB565;
                    if (!CameraDevice.Instance.SetFrameFormat(PIXEL_FORMAT.RGB565, true))
                    {
                        availableFormat = PIXEL_FORMAT.GRAYSCALE;
                        if (!CameraDevice.Instance.SetFrameFormat(PIXEL_FORMAT.GRAYSCALE, true))
                        {
                            availableFormat = PIXEL_FORMAT.UNKNOWN_FORMAT;
                            Debug.LogError("Couldnt Initiate Camera Format");
                        }
                    }
                }
            }

            var isAutoFocus = CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);
            if (!isAutoFocus)
            {
                CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_NORMAL);
            }

            Debug.Log("QR Scanner ready");

            _isInitialized = true;
            DecoderThread = new Thread(decode);
            DecoderThread.Name = "T0, _decoder";
            DecoderThread.Start();
            pauseThread = true;

        }

程序应该会在几秒钟后启动并初始化帧格式，这样我就可以调用 getCamerImage 来获取要解码的图像。它能够设置导致 GetCameraImage 错误的 FrameFormat。在 visual Studio 中构建解决方案时我发现的两个错误是：

Failed to set frame format

并且在某些原生 Vuforia 代码中：int32_t returnValue = il2cppPInvokeFunc(____licenseKey0_marshaled 它停止调试，因为某些访问被拒绝

Answer 1

通过将 RGBLuminanceSource.BitmapFormat 切换为所选 PIXEL_FORMAT 的合适格式并将 setFrameFormat 包含在 try-catch 块中解决。
