What’s the best way to set up live streaming for online education?

I’m planning to set up live streaming for educational purposes . mainly for classes, webinars, and interactive training sessions. The goal is to make the learning experience smooth, secure, and accessible across devices.

I’m open to both open-source tools and paid platforms, but I’d love to hear what others are using.
Also, if anyone has used platforms like VPlayed, Vimeo OTT, or any open-source setups, I’d love to hear your thoughts or comparisons.
