Depending on how you integrate, the experience can be radically different.
Some developers are using Genvid to stream their game from a server to provide alternative camera angles. As the broadcaster, you can decide whether you want to provide multiple camera angles to your end viewers, or if you want to only have access to the cameras on the backend and use the cameras to compose your stream (like live sports production.)
Other developers are using Genvid to make their stream fully interactive, allowing viewers to touch/click on the video’s UI, players and more to get data that is normally only available in-engine.
Finally, many developers are going the extra mile with Genvid, allowing for interaction between viewers and other viewers, via cheers, or between viewers and the game itself.
