#### ROS 2 driver for V4L2 USB cameras (Logitech C920 and others)

Snap of the ros-drivers/usb\_cam ROS 2 node.
The snap runs usb-cam node as a daemon,
sharing the ROS 2 Jazzy runtime from the `ros-jazzy-ros-base`.

Camera configuration always goes through a ROS params YAML file, matching
upstream usb\_cam's own `--params-file` interface. A managed default is
seeded at $SNAP\_COMMON/config/usb\_cam.yaml on install, including
`video_device: "/dev/video0"` by default.
This can be edited directly for full
control, or use the `video-device` key as a shortcut for the common case
of just pointing at a camera:

```
   snap install ros2-usb-cam
   snap connect ros2-usb-cam:camera
   snap set ros2-usb-cam video-device=/dev/video4 namespace=/static_camera
```

General ROS environment (ROS\_DOMAIN\_ID, RMW\_IMPLEMENTATION,
FASTDDS\_DEFAULT\_PROFILES\_FILE, ...) is set via the env-injector
extension, e.g.:

```
   snap set ros2-usb-cam env.ros-domain-id=42
   snap set ros2-usb-cam env.rmw-implementation=rmw_fastrtps_cpp
```

For anything beyond the video-device path (resolution, framerate, pixel
format, brightness, camera\_info\_url, ...), edit
$SNAP\_COMMON/config/usb\_cam.yaml directly, or hand the snap a completely
separate file/URL, which takes precedence over the default file:

```
   snap set ros2-usb-cam config-file=https://example.com/usb_cam.yaml
```

To discard local edits and restore the packaged default config, run the
reset-config app (this also unsets the `video-device` shortcut so the
reset sticks), then restart:

```
   ros2-usb-cam.reset-config
   snap restart ros2-usb-cam
```

Run a second camera on the same host with snapd parallel installs
(experimental snapd feature; each instance gets its own configuration):

```
   snap set system experimental.parallel-instances=true
   snap install ros2-usb-cam_wrist
   snap set ros2-usb-cam_wrist video-device=/dev/video2 namespace=/wrist
```

The snap publishes the standard usb\_cam topics (`image_raw`, `image_raw/compressed`,
`camera_info`), scoped by the ROS namespace. The `camera_name` parameter
is not part of the topic path -- upstream only uses it for camera
metadata (`CameraInfo`).
