-Then point each rover's `/etc/roverd.yaml` at `ws://<server>:8080/rover`, set `name` to the rover’s ID, and (optionally) override `media.publishUrl` if your control server isn’t `192.168.0.86`. The WHIP publisher service (`whip-publisher.service`) captures the Pi camera with `rpicam-vid`/`libcamera-vid`, pipes the raw H264 into the bundled `ffmpeg-whip`, and publishes straight into the server’s mediaMTX instance at `http://<server>:8889/whip/<name>`. Install `libcamera-apps` on each Pi; the installer will download the patched ffmpeg build automatically. Use the “Restart Camera” button if you enable media management so roverd can bounce the publisher service remotely.

Use the “Restart Camera” button if you enable media management so roverd can bounce the publisher service remotely.
 Heads-up: the BRC pulser now uses libgpiod; make sure the `roverd` service account is in the `gpio` group (or otherwise allowed to access `/dev/gpiochip*`) and set `brc.gpioChip` if your hardware exposes a different chip name.

-The installer downloads `ffmpeg-whip` (a WHIP-enabled FFmpeg build) and drops it at `/usr/local/bin/ffmpeg-whip`, along with its private libraries under `/usr/local/lib/ffmpeg-whip`. roverd writes `/var/lib/roverd/whip.env` on startup (and whenever you restart the service) so the publisher inherits the correct `WHIP_URL`, resolution, FPS, and bitrate. Tweak those knobs under `media.videoWidth`, `media.videoHeight`, `media.videoFps`, and `media.videoBitrate` in `/etc/roverd.yaml` if you need different camera settings.  
+The installer builds `ffmpeg-whip` (a WHIP-enabled FFmpeg) from source, installs it under `/usr/local/lib/ffmpeg-whip`, and drops a wrapper at `/usr/local/bin/ffmpeg-whip`. roverd writes `/var/lib/roverd/whip.env` on startup (and whenever you restart the service) so the publisher inherits the correct `WHIP_URL`, resolution, FPS, and bitrate. Tweak those knobs under `media.videoWidth`, `media.videoHeight`, `media.videoFps`, and `media.videoBitrate` in `/etc/roverd.yaml` if you need different camera settings. Building FFmpeg on a Pi Zero 2 W can take 15–30 minutes—let the installer finish before rebooting.  
 Use `sudo systemctl status whip-publisher` to watch the pipeline logs; the unit auto-restarts whenever the network drops or FFmpeg exits.
