Application Overview
A high-performance, browser-based diagnostic utility that allows users to verify webcam hardware functionality, stream quality, and technical metadata without downloading software or plugins.
Core Features
- Live Video Preview: Low-latency video rendering using the MediaDevices API.
- Real-Time Metadata Diagnostics: Automatically tracks and displays current video resolution (e.g., 1920x1080), frame rate (FPS), and detected aspect ratio.
- Device Selector: A dropdown menu to switch between multiple connected cameras (integrated webcams vs. USB cameras).
- Snapshot Capability: A button to capture and download a still image from the stream for quality verification.
- Permission Handling: Graceful UI states for 'Permission Denied', 'Camera Not Found', and 'Camera in Use' errors.
UI Layout
- Header: Simple, descriptive H1 tag clearly identifying the tool function.
- Control Bar: Located immediately below the header. Contains the camera selection dropdown, a refresh button to re-scan devices, and a 'Take Snapshot' button.
- Main Display Area: A large, centered, responsive container housing the
<video>element. The background will be a neutral, light gray to make the video feed stand out. - Stats Dashboard: A clean, grid-based card layout placed below the video preview displaying real-time metrics: 'Active Resolution', 'Frame Rate', and 'Device Name'.
Design & Aesthetics
- Color Palette: A clean, professional aesthetic focused on high-contrast readability. Primary background: #FFFFFF; Accents: #007BFF (Blue) for action buttons and #6C757D (Grey) for labels and borders.
- Typography: Sans-serif, system-safe fonts (Inter or Roboto) for clarity.
- Animations: Subtle fade-in transition when the camera stream initializes. Soft hover effects on buttons. No heavy animations to ensure performance.
- Mobile Responsiveness: Layout utilizes CSS Flexbox/Grid to ensure the video element scales correctly on mobile, tablet, and desktop devices.
Technical Implementation Constraints
- No Dark Mode: The application is strictly light-mode only.
- No Footer: Do not implement a footer. The interface should focus entirely on the tool functionality.
- Single-File Requirement: All HTML, CSS (in
<style>tags), and JavaScript (in<script>tags) must be contained within a single.htmlfile. - Self-Contained: No reliance on external frameworks like React, Vue, or Angular. Vanilla JavaScript is required.
- Sandboxing: The tool must be designed to function perfectly inside an
<iframe>or any standard browser window without additional configuration.
