Shame on me for putting shoddy code on the internet! Recursive is better 
for proper error handling:

    async function getSomeUserMedia({audio, video}) {
       try {
         return await navigator.mediaDevices.getUserMedia({audio, video});
       } catch(e) {
         if (e.name == "NotFoundError") {
           if (video && audio) return gUM({audio});
           if (audio) return gUM({video});
         }
         throw e;
       }
    }

    // Example usage (works with constraints as well):

    (async () => {
       try {
         video.srcObject = await getSomeUserMedia({video: {width: 1280}, audio: true});
       } catch(e) {
         console.log(e);
       }
    })();
