Peertube is a video and streming platform (like youtube) and owncast a streaming platform (like twitch) that are FOSS, self-hostable and connected to the Fediverse. Although I don't think getting any amount of viewers on those platforms will be any easier.

There is peertube, and for twitch I mean owncast exists... Odysee is also highly recommended.
Odysee is also highly recommended.

Odysee actively delists those people AFAIK... however Odysee I dont think is FLOSS, thus peertube is on a higher list than odysee... However peertube production value is still lacking in comparsion to odysee... (I do not have any political affiliation)
Youtube and other sites, like reddit rely on people using them and creating stuff to keep people around, odysee and peertube are no different in that regard.
I don't really use them because most of the people I like are on Youtube, and there are pretty good youtube clients.
There's PeerTube, and there's also LBRY.
Honestly, if you're someone making gaming videos, it's hard to find an audience in other platforms.
