return object from hook should be memoized

useMemo on

Lines 53 to 56 in c5acaae

    
           return { 
        
             stream, 
        
             error, 
        
           };

so you can use the object like:

const media = useUserMedia()

useEffect(() => {
}, [media]) // media is stable, since it's memoized

Thanks @pocesar, for pointing this out,
Do you want to create a pull request ?

Why not memoize when necessary? At the upper scope:

const media = React.useMemo(useUserMedia, [])
