I'd advise streaming through Twitch. Other than that, it's pretty relaxing just listening to the stream's music and seeing someone else play while I'm working on coding scripts :p
I'm sorry but those videos provide no strategic insight and are just colors moving on the map. Not sure why anyone would watch those videos and how they improve warzone's exposure.
Should let you stream to YT and twitch at the same time. Don't know if there are other tools as well, nor any details. Just know that restream is used.
