toposync-ext-cameras 0.1.13

Toposync first-party extension: RTSP cameras and camera pipeline operators.

Toposync Cameras extension

First-party extension focused on camera integration for the global Pipelines runtime.

What it provides

• RTSP camera settings and indexing (/api/cameras/index)
• RTSP snapshot endpoints used by UI/tools
• Control-point-set mapping endpoint for camera/composition interpolation
• Camera pipeline operators registry integration
• Camera element/editor UI in the composition

The old per-camera detections runtime (/api/cameras/detections/*, cameras.tracking, and toposync_ext_cameras.processor_server) is no longer part of this extension.

APIs

• GET /api/cameras/index
• POST /api/cameras/rtsp/snapshot
• GET /api/cameras/cameras/{camera_id}/snapshot
• POST /api/cameras/control_points/map

camera.camera_mapping and the editor now use control_point_sets as the canonical mapping model:

• fixed camera: one set with pose_reference = null
• PTZ camera: one or more sets, optionally bound to a pose_reference
• preview API: receives a single control_point_set payload and maps image <-> world

Pipeline operators (registered by this extension)

• camera.source
• camera.motion_gate
• camera.camera_mapping
• camera.area_restriction
• camera.velocity_estimation

Public vision operators are registered by the com.toposync.vision extension:

• vision.detect
• vision.track
• vision.crop_objects

Legacy vendor-specific YOLO/Ultralytics runtimes are not part of the official first-party path in this extension. If you need one of those integrations in the future, ship it as a separate package and keep vision.detect / vision.track as the public operator contract.

Dependencies

• ffmpeg must be available in PATH for snapshot capture.
• OpenCV is required by frame/motion processing:
  • uv pip install opencv-python-headless
• Vision runtimes are optional and can be installed from extensions/vision.

Snapshot tuning

• TOPOSYNC_CAMERA_SNAPSHOT_TTL_S (default: 0.8)
• TOPOSYNC_CAMERA_SNAPSHOT_FFMPEG_CONCURRENCY (default: 2)

RTSP note

Some cameras expose /stream1 and /stream2. If /stream1 is unstable for snapshots, configure rtsp_url with the substream (/stream2) explicitly.
