# streamer-tools Camera Plugin -- ${TAG}

Built from commit \`${SHA}\`.

**Nobody has yet run this plugin in the OBS GUI, on any platform.** See "What
is verified, and how" in \`README.md\` for exactly what has and has not been
checked, including which claims are backed by automated tests versus a human
watching OBS. This is why the release is a draft -- open it and click Publish
once you're satisfied.

| Platform | Archive | Notes |
|---|---|---|
| Linux (x64) | \`streamer-tools-camera-${TAG}-linux-x64.zip\` | Functionally complete and verified end to end against a real LiveKit server and a real libobs (see README); OBS GUI itself still unverified |
| Windows (x64) | \`streamer-tools-camera-${TAG}-windows-x64.zip\` | Built and tested by this workflow's Windows job; the WinHTTP backend has never been exercised against a real streamer-tools server, only a loopback test server -- see README's Windows CI section |
| macOS | \`streamer-tools-camera-${TAG}-macos.zip\` | Built and tested by this workflow's macOS job. ${MACOS_NOTE} |

## Installing

Extract the archive into your OBS plugins folder for your platform (the
default locations are easy to find online -- typically
\`~/.config/obs-studio/plugins/\` on Linux, \`%APPDATA%\\obs-studio\\plugins\\\`
on Windows, \`~/Library/Application Support/obs-studio/plugins/\` on macOS).
Each archive's top-level folder already matches the shape OBS expects there,
so extracting is the whole install step. Then in OBS: Sources -> \`+\` ->
"streamer-tools Camera" -> fill in the server URL, room slug and read key
from the room's settings page -> "Refresh camera list" -> pick a camera.

## What this is

Native OBS Studio source plugin that pulls streamer-tools camera feeds
directly from LiveKit over WebRTC. See \`README.md\` in the repository for
the full design, what is and is not verified, and current CI status.
