RTSP (eufy) streams to chrome cast and lag?

I setup a generic camera and cast that to chrome cast. Works great except lag is about …at least 20-30 seconds or so ?

It’s a eufy camera, i put the settings to the lowest.

I use WebRTC dash cast for some other Chinese made cctv camera’s which works great, but it doesn’t seem to work with Eufy’s (codec aac not supported).

camera:
  - platform: generic
