# Video Shader
Native video shader host with an OpenGL render path, pluggable video I/O boundary, DeckLink backend, Slang shader packages, and a local React control UI.
Native video shader host with an OpenGL render path, pluggable video I/O boundary, DeckLink and NDI backends, Slang shader packages, and a local React control UI.
The app loads shader packages from `shaders/`, compiles Slang to GLSL at runtime, renders a configurable layer stack, and exposes a browser-based control surface over a local HTTP/WebSocket server. Shader compilation is prepared off the frame path where possible, then committed on the render thread so editing shader files does not block video output for the whole compile.

- `runtime/`: shader catalog support, layer model, Slang build bridge, font atlas build, and runtime-state persistence.

- `video/core/`: backend-neutral video IO handoff contracts, mode descriptions, pixel formats, and output scheduling thread.

You can run `RenderCadenceCompositor.exe` directly from that folder. In packaged mode, the app resolves `config/`, `shaders/`, `3rdParty/slang/bin/slangc.exe`, `3rdParty/msdf-atlas-gen/msdf-atlas-gen.exe`, `ui/dist/`, and `runtime/templates/` relative to the exe folder. In development mode, it still falls back to repo-root discovery.

The install step copies only the Slang runtime files required by the shader compiler (`slangc.exe`, `slang-compiler.dll`, and `slang-glslang.dll`) plus `third_party_notices/SLANG_LICENSE.txt`. It also copies `msdf-atlas-gen.exe`, any adjacent `msdf-atlas-gen` DLLs, and the `third_party_notices/MSDF_ATLAS_GEN_LICENSE.txt` and `third_party_notices/MSDF_ATLAS_GEN_README.md` notice files.
