Best Practices
Follow these guidelines to implement media capture effectively in your applications.
Performance Optimization
- Request appropriate resolution and frame rate for your use case
- Release media streams when they're no longer needed
- Handle device changes and disconnections gracefully
- Implement proper error handling for device access
- Consider using WebRTC for real-time communication
- Optimize video quality based on network conditions
Security & Privacy
- Always request user permission before accessing media devices
- Use HTTPS for secure media capture
- Implement proper access controls for your application
- Handle device permissions appropriately
- Consider implementing device selection for multiple devices
- Provide clear feedback when devices are in use
Error Handling and Edge Cases
Common Issues
- Device permission denied
- Device not found or disconnected
- Insufficient system resources
- Browser compatibility differences
- Multiple device handling
Handling Strategies
- Implement proper error handling for device access
- Provide fallback options when devices are unavailable
- Handle device changes and reconnections
- Implement proper cleanup of media streams
- Use feature detection for browser compatibility
