Android 5.0预览表面上的裁剪区域错误并捕获了静止图像

我正在尝试在带camera2界面的Android 5.0上获得数字缩放框. 该功能的适当文档为 developer.android.com/camera2/captureRequest

I'm trying to get digital zoomed frame on Android 5.0 with camera2 interface. Appropriate doc for that functionality is developer.android.com/camera2/captureRequest

应用程序中使用的表面:

Surface used in my application:

• SurafaceView(1920x1080，16:9宽高比)
• ImageReader(3264x2448，4:3纵横比)

相机的传感器尺寸为3280x2464(长宽比为4:3)

Camera's sensor size is 3280x2464 (4:3 aspect ratio)

我想从传感器获取的作物区域是:

Crop region which I want to get from sensor is:

Rect zoomCropPreview = new Rect(1094, 822, 2186, 1642); //(1092x820, 4:3 aspect ratio)

我将此Rect设置为预览请求的参数:

I set this Rect as parameter for preview request:

previewRequestBuilder.set(CaptureRequest.SCALER_CROP_REGION, zoomCropPreview);
captureSession.setRepeatingRequest(previewRequestBuilder.build(), null, null);

并拍摄静止图像:

stillRequestBuilder.set(CaptureRequest.SCALER_CROP_REGION, zoomCropPreview);

captureSession.capture(stillRequestBuilder.build(), new captureListener() , null);

预期结果:

• Coz裁剪矩形比例为4:3，则预览应垂直裁剪(字母框)
• 静止图像应该是准确的作物区域.
• 预览和静止图像都应在场景的同一点上居中，并且仅在垂直边缘上应有所不同.

实际结果:

• 预览和静止图像指向似乎垂直移动的不同场景.查看附加图像.

• Preview and still image point on different scene which seems to be moved vertically. Look at attach images.

我在做什么错了?
