I haven't found a UI component in vMix to selec tbetween Uni- or Multicast. If the software option isn't possible at your end connect the vMix output to a spark. The hardware encoders seem to be able to use multicast as an option.
NDI isn't really build for display delivery. How would you decode the NDI at the displays?

Hi guys, I have not been able to solve my problem. Is there anyone here who uses NDI in multicast mode? I want to stream NDI output from VMIX to multiple large monitors (NDI Monitor) during an event on Sunday. I can't turn on multicast mode. I am using Windows 10, running Access Manager from Administrator. IGMP Snooping is enabled on the managed switch. I don't know what to do. Please help.

I can't ask a question on the Newtek forum yet. For two days waiting for the registration confirmation by the administrator.

Now I understand that vMix does not support multicast. Looking for another solution.

I have three real-time screens on stage and four screens outside the hall. I wanted a universal solution, but probably will have to connect the stage by NDI, and others by RTMP.

Thanks, man! I'm gonna try FFMPEG or VLC for Multicast UDP.

@DWAM - I wish I could capture all your experience with the FFMPEG to RPi designs because all the searching and reading failed attempts is daunting for me.

Ive had issues with FFMPEG packages on the pi with memory leaks and shutdowns usually stemming from trying to solve latency issues with flags such as -live.

I wish there was a sticky with the latest info on most recent technologies to simplify a task that, as you've mentioned many times, has been addressed a lot - Low latency video for LAN distribution. It's just all broken down into so many bits and pieces, it's hard to sort the best methods from the overly complicated.

Im going to keep searching here for the exact methods on the command line for FFMPEG sends (multicast UDP)... but for the rpi, which distro and player have you had success with? And 500ms? I wish more examples of this were documented. Or methods where other STB were used.

My vMix has 1 SDI and 1 NDI camera coming in,
with 1 SDI out, but I also need to send to 5 other in-house locations (2 of which I think I need to find a wireless method *ugh* and 1 where latency is an issue). The final 2 don't matter as much and they're wired. I wish NDI was better suited for distribution. It feels simpler... but I'm not experienced in working solutions yet - just failed attempts haha.
