outputs |
✅ |
Non-empty list of outputs; one frame stream is produced per entry, with their per-output pixel formats. A single shared expression DAG is synthesised across all outputs, so common subtrees (sources, resizes, tone maps, …) are evaluated once. |
|
build_options |
Per-build knobs. Optional — leave unset for historic default behaviour. |

nvidia_output |
When true, the spectrum processor runs its GPU-mode pipeline regardless of whether the input frame is a host (InMemory) or an NVIDIA surface, and emits nvidia-output frames. Use when the downstream consumer (e.g. nv-h264 encoder) expects a GPU surface and you want to avoid the host→GPU bounce that would otherwise happen via a separate PayloadToSurface processor. Default false (today’s host-in/host-out or gpu-in/gpu-out behaviour, inferred from the input). |
