Posting to make it clearer on what’s possible and what’s not, at this time
1. Using the plugin alone, only admin can broadcast; you may use the static rtmp feature and distribute RTMP URLs to broadcasters, this way they can broadcast without actually interacting with the backend
2. If using the theme, it is possible to enable broadcasting for regular users, see this and this
3. Broadcasting in PPV as a regular user is not yet supported; it has been requested repeatedly and we are considering it for the next release; you can upvote it right here
4. Setting up multi-vendor (#3 assumes all funds go to admin) is a more complex undertaking and honestly not a very popular one; we will still consider it if asked for repeatedly
