@어부지망생 i used CsWin32 to source gen the pinvoke definitions and stuff

using System.Runtime.InteropServices;

using Windows.Win32.UI.Input.KeyboardAndMouse;

var input = new INPUT[2];

input[0].type = INPUT_TYPE.INPUT_KEYBOARD;
input[0].Anonymous.ki.wVk = VIRTUAL_KEY.VK_MEDIA_PLAY_PAUSE;

input[1].type = INPUT_TYPE.INPUT_KEYBOARD;
input[1].Anonymous.ki.wVk = VIRTUAL_KEY.VK_MEDIA_PLAY_PAUSE;
