added getVideoTrack function to imperative ref. So

[jmschrack]

This exposes a getVideoTrack function to get the current VideoTrack. This way the end user can modify advanced constraints themselves.

Example of setting the Saturation value on a camera:

'use client'
import { useEffect, useRef,useState } from "react";
import { Camera } from "react-camera-pro"

export function Cam(){
    /**@type {import("react").MutableRefObject<import("react-camera-pro").CameraType>} */
    const camera = useRef(null);
    const [val,setVal]=useState(50);
   
    useEffect(()=>{
        if(camera.current){
            camera.current.getVideoTrack()?.applyConstraints({advanced:[{saturation:val}]});         
        }
    },[val])
    
    return (
      <div className="">
        <div className="h-32 w-32 max-h-32"><Camera ref={camera} aspectRatio={4/3}/></div>
        <input type="range" min={0} max={100} step={1}  className="range" value={val} onChange={(e)=>{setVal(e.target.valueAsNumber)}} />
      </div>
    );
}
