Not sure if people overcame this problem or not but when I tried my Reolink 410 5 MP with the following URI it worked no problem, it is the same URI I use in Home Assistant and what I pass to VLC:

rtsp://camera-sidedoor.iot/h264Preview_01_main

Or for Home Assistant:

rtsp://user:password@camera-sidedoor.iot/h264Preview_01_main

Latest upgrade from 7/10/2020 for the E1 Zoom fixed this problem for me link

I imagine a pro fix is either out already or right around the corner.
