ARM上的MediaExtension死锁 [英] MediaExtension deadlock on ARM

问题描述

您好。

基于示例MediaCapture - GrayscaleTransform我使用MediaExtension时遇到问题。 

I have problems using MediaExtension based on the sample MediaCapture - GrayscaleTransform. 

简单地说，我们使用这个dll捕获网络摄像头流并将其传递回C＃应用程序，该应用程序处理它（AR，写入纹理...）。应用程序在PC上正确运行（x86和x64平台）。 ARM平台上出现问题 - Surface
RT。在Debug配置中，它只处理一个样本并卡住。在Release配置中，它处理少量样本（3-6），然后结束相同的样本。每次我暂停调试器时，我都可以在一个线程上找到一个类似的callstack：

Briefly, we use this dll to capture the webcam stream and pass it back to the C# application, which process it (AR, write to texture...). The application runs on the PC correctly (both x86 and x64 platforms). The problem occurs on ARM platform - Surface RT. In Debug configuration it process just one sample and stuck. In Release configuration it process few samples (3-6) and then ends the same. Everytime I pause the debugger I can find one similar callstack on one thread:

它永远不会继续这个线程。我认为WaitForSingleObject永远不会完成，但问题是为什么。由于它不在我的代码中，我几乎猜不到，所以希望你能给我一些提示，继续可能不满足于什么条件。

And it never continues on this thread. I think that WaitForSingleObject never finish, but the question is why. As it is not in my code I can hardly guess, so hope you can give me some hint, what condition may not be satisfied to continue.

谢谢，
