RSTP Stream connection

Hello,
Im using blynk @ my home, 3 DHT 22 sensors, 8 relays, for steering blinds and roof actuators and it’s not the end:)
What I’m miss
ing is one functionality in app, rstp stream view.
I got two cameras at home, it will be very usefull if i can put in app RSTP stream in format rstp://login:pass@ip/Streaming/Channels/1. or something similar
I think the functionality is simple to implement, and it will be good to have all in one place:)

@elgato What cameras do you use?
