Hi,

**Description**  
I am trying to unsderstand how to properly deallocate a video container with video elements in it. I am calling DestroyVideoElement for each element included but I always get SDKERR\_UNINITIALIZE. DestroyAllVideoElement does the same.  
What’s the proper way to deallocate a video element and video container created with CreateVideoContainer/CreateVideoElement?

**Which version?**  
C# Wrapper v4.6.21666.0427

**Device (please complete the following information):**

- Device Spec: PC
- OS: Windows
- Version 10

Hi @bragma,

Thanks for the post. For some reasons, this “destroy video element” feature is not working as expected in the C# wrapper. However, the underneath interface DestroyAllVideoElement on Windows SDK is working well. If you would like to have the fix right now, you may modify the following files in the C# wrapper:

- customized\_video\_container\_dotnet\_wrap.h
- customized\_video\_container\_dotnet\_wrap.cpp

Hope this helps. Thanks!
