Live View & OSD

Live view streaming with optional camera UI overlay

Per-camera live view with optional OSD (On-Screen Display) overlay. All endpoints are scoped to a specific camera.

See the auto-generated API reference for full request/response schemas.

Workflow

1. Enable or start live view

   POST /api/cameras/{id}/live-view/enable or POST /api/cameras/{id}/live-view/start

2. Get frames

   GET /api/cameras/{id}/live-view/frame returns a single JPEG frame

3. Optional: enable OSD

   POST /api/cameras/{id}/live-view/osd-enable

4. Get OSD frames

   GET /api/cameras/{id}/live-view/osd-frame

5. Stop live view

   POST /api/cameras/{id}/live-view/stop

Endpoints

Method	Path	Description
POST	/api/cameras/{id}/live-view/enable	Send SDK Setting_Key_EnableLiveView
POST	/api/cameras/{id}/live-view/disable	Disable live view
GET	/api/cameras/{id}/live-view/status	Returns enabled + streaming booleans
POST	/api/cameras/{id}/live-view/start	Start the frame capture worker (auto-enables live view)
POST	/api/cameras/{id}/live-view/stop	Stop the frame capture worker
GET	/api/cameras/{id}/live-view/frame	Latest JPEG frame (Content-Type: image/jpeg)
POST	/api/cameras/{id}/live-view/osd-enable	Enable OSD overlay
POST	/api/cameras/{id}/live-view/osd-disable	Disable OSD overlay
GET	/api/cameras/{id}/live-view/osd-status	Returns supported + enabled
GET	/api/cameras/{id}/live-view/osd-frame	Composited JPEG (live view + OSD)

Live view is disabled by default in remote-transfer mode. You must call /live-view/enable (or /live-view/start which auto-enables) before requesting frames.

Get Frame

Returns the latest live view frame as a JPEG image. Streaming must be started first.

curl

curl -o frame.jpg http://localhost:8080/api/cameras/D10F60149B0C/live-view/frame

OSD Overlay

Enable on-screen display — the camera renders its UI (exposure info, focus points, histogram, etc.) as an overlay image composited onto the live view frame.

curl -o osd-frame.jpg http://localhost:8080/api/cameras/D10F60149B0C/live-view/osd-frame

Two things build on live view. Focus overlays are drawn from AF Frame Position and Remote Touch and Tracking, which report frame coordinates normalized to whatever size you render at. And the OSD frame paired with Button Press is enough to drive the camera’s own menus remotely — press, then read the screen back.

Polling for continuous frames

For a render loop at ~15 fps, poll GET /api/cameras/{id}/live-view/frame at roughly 66 ms intervals. The endpoint returns the latest JPEG the server has captured — the camera-side frame rate is the actual cap.

See the live-view polling example for full client implementations in TypeScript, Python, and Swift.
