A reference architecture for live streaming at scale: what each stage does, how to size egress bandwidth for thousands of concurrent viewers, where high-concurrency events fail first, and what to ask a provider before a big stream.

How to add live workout classes to your own app: what a class needs from the video layer, when to use a real-time room or HLS, React quickstart code where the instructor hosts and the class watches, and a cost formula for one class.

hls.js is an HLS engine; Video.js is a player with its own engine. This comparison covers low-latency HLS, live-edge controls, Safari and iPhone behaviour and bundle sizes, with each project's version checked on 29 September 2026.

A watch party needs three parts: a video room for the group, a shared player and a sync channel. This guide compares three co-watching architectures, explains drift correction, and builds the room with the VideoSDK React quickstart.

RTMP, SRT and WHIP all carry live video from an encoder to an ingest server, but they fail differently on bad networks and suit different sources. This guide compares them against their specs and gives a rule for choosing one.
