VLC plugin: Windows SMTC integration

Plugin that integrates VLC Media Player with Windows System Media Transport Controls (SMTC)

• VLC 3.0.x or VLC 4.0.0-dev nightly
• Windows 10 Version 1607+ or Windows 11
• Microsoft Visual C++ Redistributable 2022 or later, for the same architecture as VLC

1. Download the plugin matching your VLC architecture from GitHub Releases
   • Note: the plugin architecture must match vlc.exe, not Windows (eg: an x86 plugin does not work with x64 VLC)
2. Extract libwin10smtc_plugin.dll to <path-to-VLC>\plugins\misc
3. Restart VLC and navigate to Advanced Preferences -> Interface -> Control Interfaces
4. Check Windows SMTC integration and hit Save

Official VLC build instructions recommend mingw. However, mingw doesn't support C++/WinRT, so for this plugin MSVC is used instead. In order to build this plugin you'll need: Visual Studio, Windows 10 SDK and VLC SDK:

1. Fetch the VLC SDKs: .\tools\fetch-sdks.ps1 (run from a Developer PowerShell; needs 7-Zip)
2. Load .sln file in Visual Studio
3. Select target architecture
4. Build solution
