There are other alternatives to live streaming besides YouTube, although there used to be more. Some have been purchased by bigger companies, like Vimeo bought Livestream and IBM bought Ustream. Justin.TV morphed into Twitch. There are some other independent streaming sites though.
It doesn’t take much to do it. You need a good video camera with the ability to attach it to your computer, which must have a video capture card (or external USB video capture device). You probably already have a mixer and microphones, so the rest is easy. I proposed using Ustream to conduct statewide meetings for the state agency I worked for about 7-8 years ago, as it could have saved a lot of time and money by not having people traveling from every corner of the state to Oklahoma City. I even did a demo at one of our meetings. Unfortunately, back then, I did not have all the audio gear I have now, so I could not produce the audio quality I could now. The good thing about something like Ustream is nobody is moderating YOUR stream, and the only people who see it are those you invite. So nobody will cut off your stream when you play copyrighted music. You could do pretty much the same thing with Zoom or Microsoft Teams, or even WebEx.
