/**
 * The `VideoCaptureConstraints` service provides various video capture constraints
 * including resolution and frame rate settings for different display sizes (landscape, portrait, and neutral).
 *
 * @service
 * @example
 * ```typescript
 * import { VideoCaptureConstraints } from './path/to/video-capture-constraints.service';
 *
 * constructor(private videoConstraints: VideoCaptureConstraints) {
 *   console.log(this.videoConstraints.hdCons); // Access HD constraints
 * }
 * ```
 *
 * @remarks
 * This service contains predefined constraints that can be used for video capture
 * settings based on the desired quality and aspect ratio. These constraints can
 * be applied when requesting media streams from the user's camera.
 *
 * @property {Object} QnHDCons - Video capture constraints for QnHD resolution (320x180).
 * @property {Object} sdCons - Video capture constraints for SD resolution (640x360).
 * @property {Object} hdCons - Video capture constraints for HD resolution (1280x720).
 * @property {Object} fhdCons - Video capture constraints for FHD resolution (1920x1080).
 * @property {Object} qhdCons - Video capture constraints for QHD resolution (2560x1440).
 *
 * @property {Object} QnHDConsPort - Video capture constraints for QnHD resolution in portrait mode.
 * @property {Object} sdConsPort - Video capture constraints for SD resolution in portrait mode.

 * @property {Object} fhdConsNeu - Video capture constraints for FHD resolution in neutral mode.
 * @property {Object} qhdConsNeu - Video capture constraints for QnHD resolution in neutral mode.
 *
 * @property {number} QnHDFrameRate - Frame rate for QnHD video capture (5 FPS).
