Thomsch I got mine to work by disabling GPU acceleration in the General settings and then restarting Teams. On my system with an Intel GPU, NDI would be selectable after a reboot but would then turn off with the "NDI is not supported" error as soon as I started a meeting. Interestingly enough, after I disabled GPU and enabled NDI, I was then able to turn GPU acceleration back on and NDI continued to work (at least for now.)

Hopefully this works for other people - we'll see how it goes over the next few events.

Hello, I have now found out what is wrong with me. For this project, we use a connection at the customer's premises. This apparently runs through a proxy or something similar that blocks the communication of NDI in teams. When I try to activate NDI in the same setup via an LTE router, it works immediately. Even without restarting teams. Then I can reconnect the PC to the home network and use it.

But now I have the problem that I can see the users via NDI in VMix. BUT now I only get a black picture in VMix and no audio signal. If I switch back to the LTE connection, I immediately have picture and sound again.

Funny is that I have no problem with NDI via MAC (OSX 10.15.7. Teams version 1.4.00.4971). There I can activate NDI in the company network and also get picture and sound in VMix.

There are two issues I have seen that cause the Black Video.

1) You may need to ensure the Network connection is on PRIVATE network and not Public.

a. Go to Network and Internet Setting control panel

b. Select Ethernet

c. Select the Adaptor you are using

d. Select Private

2) There is a local windows firewall blocking the connection to the Computer running your switcher software. You can confirm this if you go into your firewall settings and see if the IP address of that Switcher computer is showing a blocked communication.

hope this helps
