Windows Graphics Capture 示例需要较高的Windows版本:
Windows Version >= 10.0.17134.48(akaWindows 10 Version 1803)Windows SDK Version >= 10.0.20348.0FFmpeg >= 6.0
如果你的Windows或SDK不能满足要求，你可以选择:
- 通过
-DDISABLE_WGC=ON来禁用Windows Graphics Capture示例 - 通过
Visual Studio Installer安装最新的Windows SDK
Version : > 4.3 (-DDISABLE_WGC=OFF : >= 6.0)
- Windows builds: 注意下载
shared版本，添加到环境变量中 - Build from source
6.0 > Version >= 5.12
- Download: 安装后注意添加目录到环境变量中
