It should be do-able. Our Nordictrack incline trainer has this feature. It's pretty cool because you can design a route on google maps and then go running anywhere you want. I've used it to jog through neighborhoods in cities I used to live in, etc. It's not video (obviously). It's just a sequence of still frames, but it syncs to the speed your running at, so it's pretty realistic. They also offer full video runs in beautiful locations, but it doesn't sync to your speed, and you can't control the route. Somebody should definitely do this for indoor biking. I actually sent an email to Peloton requesting the feature.
