# EVE Program Output
|
|
|
|
## Authority Map
|
|
|
|
- Owner: Fensalir owns the visible D3D12 program pixels.
|
|
- Inputs: Fensalir reads the current `AquariumFrame`, render plan, GPU resources,
|
|
and overlay state.
|
|
- Outputs: a named shared D3D12 `B8G8R8A8_UNorm` texture containing the completed
|
|
backbuffer for the current frame.
|
|
- Derived state: Mimir publication profiles describe the stream contract; they
|
|
do not render pixels. EVE receives decoded pixels and composites them.
|
|
- Forbidden writers: WebKit, DOM layout, browser dashboards, OBS capture, and
|
|
desktop/window capture do not own this path.
|
|
- Shared paths: local display and EVE streaming both use the same completed
|
|
Fensalir backbuffer copy.
|
|
- Deletion line: diagnostic Sunshine/Moonlight or desktop-duplication probes may
|
|
prove network/decode budget, but they are not production authority.
|
|
|
|
## Current Mechanism
|
|
|
|
Set these before launching the Mimir app:
|
|
|
|
```powershell
|
|
$env:FENSALIR_PROGRAM_OUTPUT_D3D12 = "1"
|
|
$env:FENSALIR_PROGRAM_OUTPUT_NAME = "Global\MimirFensalirProgramTexture"
|
|
dotnet run --project .\src\Mimir.App\Mimir.App.csproj
|
|
```
|
|
|
|
Fensalir creates a shareable D3D12 texture with that name and copies the finished
|
|
backbuffer into it during the present pass. A hardware encoder process should
|
|
open that named texture, encode H.264/HEVC with GPU hardware, and send frames to
|
|
EVE's native receiver.
|
|
|
|
`scripts/start-eve-program-output.ps1` starts the Mimir/Fensalir app with the
|
|
shared-texture output enabled and verifies the `eve` SSH target before launch.
|
|
|
|
## Receiver Contract
|
|
|
|
EVE owns:
|
|
|
|
- network receive;
|
|
- hardware decode;
|
|
- texture upload/import;
|
|
- final fullscreen composite;
|
|
- touch/Pencil/sensor uplink later.
|
|
|
|
EVE does not own:
|
|
|
|
- dashboard DOM;
|
|
- Chromium/WebKit compatibility;
|
|
- layout parity;
|
|
- Mimir timing authority;
|
|
- OBS composition authority.
|
|
|
|
## Smoke
|
|
|
|
```powershell
|
|
dotnet run --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --eve-program-output-contract-smoke
|
|
```
