Improve quality of a Teams screen-shared video?
erimo This issue was resolved. However, in order to resolve it, we needed to know how networking works in Teams. Here's a great video. https://youtu.be/vi3M7ZzF2NU It's about an hour long, but well worth it.
We put together a few test cases to verify the components of the system we control, specifically, the end points. We did a direct call between computers on the same LAN and attempted to stream the video. Fail. Since this case did not require any communication to the Microsoft Cloud (see the video), we were able to identify that the source computer just didn't have enough horsepower. After switching to a more powerful computer, we could stream video up to 720p without any performance issues. We brought the Microsoft Cloud into the loop by changing from a direct call to a meeting. There was virtually no difference in performance.
In further testing, we found anything less than an i5 would struggle. But as long as you have a decent machine and work within Microsoft's network guidelines, everything seems to run pretty well.
At least that is our experience...
Brounzer We have a similar issue. Our customer wants to perform new employee training using Teams Meetings to multiple regional sites. All the desktop specs in Task Manager seem to be OK (although the network bandwidth seems to flatline at 2 Mbps), and the Call Analytics in Teams show good quality connections. The customer is willing to pay for better hardware, but I can't seem to determine which part of the system is the bottleneck. I have had some success in reducing the resolution of the videos down to about 360p, but something doesn't feel right about that solution. It seems like we just need a little more insight into how Teams is handling the shared desktop apps.
Any news or solutions regarding this issue?

DisputedPondThanks for sharing. Still, when starting from Brounzer 's original question, it feels like optimising what is essentially a workaround, since it still relies on locally playing a video and sharing your screen + system audio.
Ideally, it should be possible to let a presenter start the streaming of a video straight from a server (MS Stream/Youtube/etc.) to each individual participant. I.e. without the other participants having to click on a link (in the meeting chat) or without having to move to a different window.
Is there any way to do that in Teams meetings now or to get that implemented in the nearby future?
Many thanks.
- Centrally hosted and only relying on download speed. This is what I would have hoped was possible. It doesn't seem to be a widespread approach to synchronize web video, but if we host the video in Microsoft Stream, it would be great if we could share from the server to each attendee, rather than render the video on a machine and present a screen playing the video into the meeting.
- Thanks. Are you on Windows or Mac. Does it make a difference though?
erimo I'm on Windows. I don't have any experience on Mac. I don't recall anything that states the Mac client would operate differently, but I tend to gloss over information related to Macs. My memory may be faulty.
DisputedPond Even using Corei7 10th generation with 32GB memory and electronic HD, problem remains
