+# local_video
+
+Two examples demonstrating capturing frames from a local camera video and publishing to LiveKit, and subscribing to render video in a window.
+
+- publisher: capture from a selected camera and publish a video track
+- subscriber: connect to a room, subscribe to video tracks, and display in a window
+
+LiveKit connection can be provided via flags or environment variables:
+- `--url` or `LIVEKIT_URL`
+- `--api-key` or `LIVEKIT_API_KEY`
+- `--api-secret` or `LIVEKIT_API_SECRET`
+
+Publisher usage:
+```
+ cargo run -p local_video --bin publisher -- --list-cameras
+ cargo run -p local_video --bin publisher -- --camera-index 0 --room-name demo --identity cam-1
+
+ # with explicit LiveKit connection flags
+ cargo run -p local_video --bin publisher -- \
+   --camera-index 0 \
+   --room-name demo \
+   --identity cam-1 \
+   --url https://your.livekit.server \
+   --api-key YOUR_KEY \
+   --api-secret YOUR_SECRET
+```
+
+Subscriber usage:
+```
+ # relies on env vars LIVEKIT_URL, LIVEKIT_API_KEY, LIVEKIT_API_SECRET
+ cargo run -p local_video --bin subscriber -- --room-name demo --identity viewer-1
+
+ # or pass credentials via flags
+ cargo run -p local_video --bin subscriber -- \
+   --room-name demo \
+   --identity viewer-1 \
+   --url https://your.livekit.server \
+   --api-key YOUR_KEY \
+   --api-secret YOUR_SECRET
+```
