When I use the sample to play RTSP media, it prompts me to upgrade the dll file

INFO:
the following components on your computer must be updated before you can enjoy protected content
FirewallAPI.dll

error code:0xC00D2EF9

Samples:Microsoft SDKs\Windows\v7.1\Samples\multimedia\mediafoundation\protectedplayback

Although this is a sample for Windows7, I am running on Windows10

我在win10运行了Win7的样本

尝试播放RTSP流媒体时 提示我更新FirewallAPI.dll文件 。
播放器弹出的错误代码是0xC00D2EF9

该RTSP流媒体在VLC中是可以播放的

请问如何解决这个问题。
另外我最终目的是用media foundation播放海康威视的视频流
我的系统是Win10

    Hello,

    Welcome to Microsoft Q&A!

    The problem does exit on Windows10 but Windows11. I’m digging into the problem. And according to 0xC00D2EF9 HRESULT Values, It seems the network firewall is the source.

    Packets are not being received from the server. The packets might be blocked by a filtering device, such as a network firewall.

    Thank you.
