Instant replay, recording and snips for Exo Launcher. Exo starts it as an add-on (addons\capture) and talks to it over NDJSON on stdin/stdout.
- Windows.Graphics.Capture for the game window or screen, converted on the GPU (D3D11 video processor) and encoded with the GPU's Media Foundation encoder (NVENC, AMF or Quick Sync).
- Instant replay keeps encoded video in memory and writes MP4 only when you save.
- When Windows capture gets no picture from a game (exclusive full screen), it can use OBS Studio's own signed game capture hook. See
third_party/obs/README.md.
Build: pwsh -File build.ps1 (Visual Studio C++ tools, CMake and Ninja). Output: out\ExoCapture.exe plus out\obs.
