Hello
we use Logitech Rally webcam for our meeting room which provides great picture.
However as soon as the presenter starts to share content on a Teams meeting, the quality of the video stream gets degraded significantly. Bandwidth is not an issue.
Please advise how this can be resolved.

Does this issue persist all the time?
Does anyone else have the same problem in your organization
Have you tried to login Teams web client to see if it can be fixed?
At present, it recommends you try to delete the cache of Teams by following these steps:
- Close Teams (dont forget the background process)
- Go to %appdata%\microsoft\teams
- Delete all files and folders here
- Start Teams again

This happens to all presenters (not just one) so not client related.
It happens on both wifi (cca 100Mbps) and LAN (300Mbps) so not bandwidth related.
When the presenter is not presenting content but receiving content, the quality is excellent.

It recommends you check if the ports UDP 3478 – 3481 are opened on firewall. Then, optimize your network by referring to this article:
https://learn.microsoft.com/en-us/microsoftteams/prepare-network#network-optimization.
If no luck, go to Microsoft 365 admin center > Health > Service health > Microsoft Teams to check if Teams shows any exception status.

I am experiencing this exact problem with a Logitech Rally camera within a Teams room. Was there a resolution to this problem?

Nick Iadicicco 0 Reputation points2023-05-26T14:20:21.53+00:00 My opinion is that this is not a problem. I think the resolution of the camera video is lowered because when sharing, the presenter's camera video is a PiP to the remote users. Teams' output resolution is 1080p. The decreased resolution of the camera is the size of the PiP.
This was brought to my attention inside of my organization, so I did some searching, which is how I found this thread, but I was unable to find any written Microsoft documentation describing this. The above is my opinion from being in the A/V industry for a long time.

They were one of the initial platforms to provide NDI for broadcasters to use their platform but fail in understanding that the broadcasters need quality video. They degrade the video call wide rather than on a per connection basis. I have 3Gbps symetrical coming in, and as soon as 6+ people come into a call, the quality drops to 240p for everyone. Hardline ethernet for all participants, high quality cameras, etc... Teams has built their platform for the bottom tier meeting requirements and doesn't see the need to increase quality since we all need to pay for it anyway.
