Filming / Recording Gigs / Sessions

Going to stick this here rather than in the Musicians category, although don’t mind if it gets moved.

My local pub has started putting on more and more live music, and I’m kind of interested in understanding what options there might be for filming and potentially streaming the gigs (the pub are on board with the idea). Does anyone have any experience in this area? Guess initially it would be figuring out whether there is some entry level equipment that could do a decent enough job without making a massive investment in terms of cash and time learning all sorts of technical stuff.
