# video-shader
|
|
|
|
Milestone 1 is a Windows x64 native service that captures DeckLink video, processes frames as `RGBA16f` through a D3D11 HLSL shader, and outputs the processed image on the same DeckLink device.
|
|
|
|
## Build
|
|
|
|
```powershell
|
|
cmake --preset windows-debug
|
|
cmake --build --preset windows-debug
|
|
```
|
|
|
|
Run:
|
|
|
|
```powershell
|
|
.\build\windows-debug\Debug\video-shader.exe
|
|
```
|
|
|
|
Open `http://127.0.0.1:8080`.
|
|
|
|
## Notes
|
|
|
|
- The DeckLink SDK must remain at `3rdParty/Blackmagic DeckLink SDK 16.0`.
|
|
- Milestone 1 captures video only. Audio is intentionally not routed yet.
|
|
- The processing boundary is D3D11 `DXGI_FORMAT_R16G16B16A16_FLOAT`.
|
|
- The current implementation uses an isolated CPU DeckLink bridge around the D3D11 processing core. The GPU Direct/D3D11 interop point is kept behind the frame bridge boundary for a later allocator-backed implementation.
