Camera Test

The Camera Test opens a live preview from your webcam using getUserMedia and reports the negotiated resolution, frame rate, and facing mode. It requests an ideal stream of 1280×720 at the user-facing camera. When you stop the test, every video track is stopped and the stream is released.

1. Click Start Camera — your browser will prompt for camera permission; click Allow. 2. The live preview renders in an autoPlay muted video element. 3. Below the preview, three cards show Resolution (width×height), Frame Rate (rounded to whole fps), and Facing Mode. 4. Click Switch Camera to re-acquire, or Stop Camera to release the stream.

The stream is requested with constraints { width: ideal 1280, height: ideal 720, facingMode: 'user' }. The reported values come from MediaStreamTrack.getSettings() — actual resolution may differ from ideal depending on the hardware (e.g. 640×480 or 1920×1080). Frame rate is rounded; if the browser omits it, 'Unknown' is shown. Facing mode is capitalized for display.
