You will need some way of streaming. You can try twitch or kick, though if you get too many viewers they'll nuke your channel. The stream provider I use is 8chan.tv, I don't use 8chan but it's a good streaming platform hosted by people who are fine with you showing copyrighted content. Cytube is a chatroom you use to embed streams or media into - if you had a direct link to an mp4 for the thing you want to stream you could just plug that into cytube directly and not need to even do any streaming yourself. But that's tougher to do.
>whats the legality of it
You won't get in any legal trouble if that's what you're wondering. You might get banned off of something like Twitch if you stream movies but they won't come after you. Big companies don't really care about individuals, especially ones only streaming to a dozen or so people. There's no reason you would get prosecuted for it
