It appears that this NDI plugin may not support multicasting. With multicast enabled 1Gb switches, and endpoint NDI decoders set to pull from a single multicast feed, the signal is still replicated in OBS. A single signal results in eating up ~700Mbps due to our multiple endpoints, and this is problematic since we are also live streaming, so had to turn down the baud to prevent dropped frames.
Can anyone confirm if it supports multicasting, and how to enable it?
Alternative NDI integration with OBS
If it does not support multicasting, is there another efficient way to integrate NDI with OBS?
We use both encoding and decoding of NDI in OBS.
Yep, this should help
