 *
 * @param {SwitchUserVideoOptions} options - The options for switching the user's video.
 * @param {string} options.videoPreference - The preferred video input device ID.
 * @param {boolean} options.checkoff - Flag indicating whether to turn off the video.
 * @param {SwitchUserVideoParameters} options.parameters - Additional parameters required for switching the video.
 * @param {boolean} options.parameters.audioOnlyRoom - Indicates if the room is audio-only.
 * @param {number} options.parameters.frameRate - The desired frame rate for the video.
 * @param {Object} options.parameters.vidCons - Video constraints such as width and height.
 * @param {string} options.parameters.prevVideoInputDevice - The previous video input device ID.
 * @param {Function} options.parameters.showAlert - Function to show alerts to the user.
 * @param {boolean} options.parameters.hasCameraPermission - Indicates if the user has camera permission.
 * @param {Function} options.parameters.updateVideoSwitching - Function to update video switching state.
 * @param {Function} options.parameters.updateUserDefaultVideoInputDevice - Function to update the default video input device.
 * @param {Function} options.parameters.requestPermissionCamera - Function to request camera permission.
 * @param {Function} options.parameters.streamSuccessVideo - Function to handle successful video stream.
