# 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.

| 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} See the "macOS packaging gap" in README |

## Installing

### Linux

\`\`\`
mkdir -p ~/.config/obs-studio/plugins/streamer-tools-camera
unzip streamer-tools-camera-${TAG}-linux-x64.zip -d /tmp/stplugin-camera
cp -r /tmp/stplugin-camera/bin /tmp/stplugin-camera/data \\
      ~/.config/obs-studio/plugins/streamer-tools-camera/
\`\`\`

Start OBS, then 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. This is the same drop-in layout
README's "Testing this by hand" documents for a source build, adapted for a
downloaded zip -- known-good on Linux.

### Windows (installation path not yet verified in real OBS)

Per \`AddExtraModulePaths()\` in obs-studio's \`UI/window-basic-main.cpp\`, OBS
on Windows searches a plugins directory for \`bin\\64bit\\<name>.dll\` plus a
sibling \`data\\\`. Unzip the archive and copy its \`bin\\\` and \`data\\\` into
your OBS plugins directory (typically
\`%APPDATA%\\obs-studio\\plugins\\streamer-tools-camera\\\`), matching the
Linux layout above. This has not been confirmed against a real OBS install on
Windows -- report back if you try it.

### macOS (installation path not yet verified in real OBS; packaging gap)

OBS on macOS loads plugins as \`<name>.plugin\` bundles under
\`~/Library/Application Support/obs-studio/plugins/\`. As of this release,
this project's \`build/package/\` output on macOS is **not yet that bundle
shape** -- see the "macOS packaging gap" section of \`README.md\`. Treat the
macOS archive here as a build-verification artifact, not a working
drop-in, until that gap is closed.

## 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.
