# sw-local-camera

Aspect-ratio-aware preview tile for the local camera, with a
"camera off" placeholder when video is muted or the stream is missing.

```html
<sw-call-provider token="YOUR_GUEST_TOKEN">
  <sw-local-camera></sw-local-camera>
</sw-call-provider>
```

Designed for small picture-in-picture-style previews — typically slotted
into `<sw-ui-call-layout>`'s `floating-video` slot or used standalone in
a settings panel. The element reads `getSettings()` on the active video
track to detect the natural orientation (landscape, portrait, or square)
and rewrites `--sw-local-camera-aspect` so its container hugs the track.

Input precedence (most specific wins): **`.stream` / `.videoMuted` >
`.call` > context**. Any of `.stream` and `.videoMuted` can be set
independently — for example, you can supply an explicit `stream` from a
"join" preview screen while still letting `videoMuted` come from
`devicesContext`.

The `mirror` attribute reflects to the host so it can be styled with
`:host([mirror])` and is the natural default for selfie cameras.
