什么时候INuiBackgroundRemovedColorStream :: GetNextFrame会一直返回E_NUI_FRAME_NO_DATA？ [英] When will INuiBackgroundRemovedColorStream::GetNextFrame return E_NUI_FRAME_NO_DATA all the time?

问题描述

我正在尝试使用后台删除功能。我在C中有一个包装器，我的主要应用程序是在C＃中。我可以很好地获得彩色帧，深度帧和骨架，并在我的应用程序中显示它们。但是，后台删除
流始终返回E_NUI_FRAME_NO_DATA（我正在使用轮询，如果没有数据则跳过它）。我知道它可以_sometimes_返回E_NUI_FRAME_NO_DATA，但在这种情况下我没有获得单帧数据。

I am trying to use the background removal functionality. I have a wrapper in C, and my main application is in C#. I am able to get color frames, depth frames, and skeleton frames fine, and display those in my application. However, the background removal stream always return E_NUI_FRAME_NO_DATA (I am using polling, and just skip over it if there is no data). I know it can _sometimes_ return E_NUI_FRAME_NO_DATA, but in this case I don't get a single frame of data.

什么可能导致这个问题？

What could cause this problem?

• 我正在后台删除流上调用ProcessDepth，ProcessColor和ProcessSkeleton。
• 我正在初始化流，并使用正确的分辨率启用它。

（我会发布代码，但因为它是在C ++和C＃之间分发的，所以流程有点棘手）。我希望有人可能会建议一个调试策略，以便我可以跟踪问题，或者提供一些我可以检查的东西。

(I would post the code, but because it's distributed between C++ and C# the flow is a bit tricky). I am hoping somebody may suggest a debugging strategy so that I can track the problem, or perhaps offer a few things I can check.

推荐答案

既然您可以使用托管代码中的后台删除API，那么为什么？使用  interop？ 查看SDK中的背景删除示例，了解托管和c ++的示例代码。如果您没有获取数据，那么
传递的数据无效。深度框架是否具有玩家面具？

Since you can use the background removal api's from managed code, why are you using interop? Have a look at the background removal samples in the SDK for sample code for both managed and c++. If you are not getting data, then the data you are passing is invalid. Does the depth frame have the player mask?
