streamvision

streamvision holds the host-neutral pieces of Roboflow Inference's video stack: camera acquisition (VideoSource and its producers), the host-neutral InferencePipeline, the stream-manager TCP client and its wire entities, and the stream-manager runtime that hosts pipelines as subprocesses. It is a sibling distribution to roboflow-workflows, installable on its own or embedded in the full Inference server.

The historical inference.core.interfaces.{camera,stream,stream_manager} import paths resolve to the same modules here when inference is installed. No gpu/jetson extra is declared: GStreamer/NVDEC support is provisioned by the Docker images, not pinned as a PyPI dependency in requirements/.

Standalone stream manager

The stream manager (python -m streamvision) needs streamvision[webrtc]; the library parts (streamvision.camera, streamvision.stream, the TCP client and entities) work without it.

STREAM_MANAGER_PORT=7070 python -m streamvision \
    --host-factory my_package.host:create_host \
    --host-setting api_key=... --warm-pipelines 1

--host-factory names a trusted callable returning a pipeline host; its module is imported before the runtime. scripts/streamvision_isolation_probe.py verifies an installed wheel runs without inference.
