# Initial plan

## Scope

The camera end to end on the Orin: capture, the live view, recording, and later
inference. Hardware facts for the current camera are in orin-nano-env-setup
`docs/impl/reports/USB-CAMERA.md`; tablet link limits in app-flutter
`docs/impl/reports/LINK-TEST-2026-10-11.md`.

## Order

0. **Live view** — in place: `src/liveview.py` as `yukart-vision.service` on
   `:7710`. Started as a test tool in app-flutter and moved here once the live
   view became a product feature (decision 27). Protocol in the module docstring.
1. **Capture fan-out.** One capture process, frames to several consumers (live
   view, recorder, inference). Needed before a second consumer exists.
2. **Recording.** H.264 in software (`x264enc`, ~1.3–2 cores at 1080p) in
   segments on the recorder's sessions, under the recordings bound.
3. **Exposure for sign reading.** Manual exposure with own metering to hold the
   frame rate; LED signs flicker under short exposures.
4. **Inference** — deferred (decision 7): road signs, speed limits first.

## Open

- The protocol lives in the docstring. It moves to contracts when a second
  client exists or it changes shape.
