// Injected Present-hook video path: hooks IDXGISwapChain::Present in the target

// (coop_video_<pid>), and publishes its dimensions/format to the host over IPC.
// The host opens that texture by name and samples it -- a lower-latency, more
// stable alternative to Windows Graphics Capture (which composites off the
// desktop and can stutter / show a capture border).
//
// Only DXGI swapchains (D3D10/11/12-backed games) are caught; the backbuffer
// must be an ID3D11Texture2D (the common D3D11 case). Games on D3D9 or a pure
// D3D12 resource path won't engage this hook -- WGC stays as the fallback.
