Which tools would you recommend for smoother streaming in a new Android application?

I’ve recently launched an Android application and I’m working on improving the streaming experience. I’m particularly interested in reducing buffering and handling different network speeds more efficiently.

For developers who have worked on video-based apps, which tools or services would you recommend for adaptive bitrate streaming, CDN delivery, video encoding, and performance monitoring? I’d like to choose a setup that can remain reliable as the user base grows.
