All three of mine have a more normal looking URL. Any other particular settings related to the video showing in your state variables maybe?:
2 of mine are xt, the 3rd is a white (Indoor).
I also noticed that LiveView only has a duration of 300... which I assume means 300 seconds. Not sure how long before a new a new URL is required though. In my testing I could request another LiveView and it would have a new URL within ~1 min (50 seconds), but when I requested one in under 30 seconds (26 to be exact) I got a 409 error (that I still need to build into the response handling).
