Stream camera to Google hub

Hi
I am trying to stream from my IP camea (Vivotek) to a google hub.
The camera is sending in h264 and I am able to expose it on nabu-casa, so the camera shows up on my hub. But when I select the stream, it just shows a black image.
Have played around with different settings, but cant seem to figure it out. Anyone that can share some knowledge about this? I have configured the camera as this in my config:

camera:

  • platform: vivotek
    name: Enterance camera
    ip_address: IPAddress
    username: user
    password: pass
    stream_path: live3.sdp

Sorry I can’t provide any incite, only to say I have the same problem with my Amcrest cameras. My network is segmented (cameras are on a CCTV vlan, Google products on an IoT vlan, and Home Assistant server on my Main vlan) and I have firewall rules blocking traffic from IoT/CCTV to the Main, but I added a rule to allow from CCTV to IoT however this didn’t solve the issue.

Hoping someone with more knowledge can chime in…
