What exactly is a SFU server and why should you need or use it? (version 5.1.0 ue5-main)

Today I’ve made a build of the new ue5-main branch. Now the packaged project with enabled pixel streaming has a new SFU server which connects to the streaming server on default port 8889. What exactly is a SFU server and why should you need or use it? Will there be also an online manual for the new pixel streaming functionalities because at the moment there are no infos and explanations about new developments.

(version 5.1.0 ue5-main)

From the release note:

“Start-up scripts have been added for Linux. These enable running of SFU server locally, and SFU and CoTURN in docker containers”

Hope that gives you a direction if you’re running on Linux
