Live audio rooms let a few speakers talk while a large audience listens and raises hands to join. How the architecture works, the features users expect, what a 500-listener room costs on VideoSDK, and how to build one in Flutter, React Native, or JavaScript.

A video codec compresses raw 720p video about 221 times so a call fits through a network. This guide compares H.264, VP8, VP9, and AV1 on compression, CPU cost, simulcast, and battery, separates codec from container and encoder, and shows how VideoSDK sets the codec and falls back to VP8.

A telehealth video platform is six layers, and the video call is one of them. This guide maps the architecture, shows what WebRTC does and does not give you, covers five telehealth UX patterns, summarizes the HIPAA controls, and prices 2,000 consults a month.

A video call API runs the signaling, media servers, and TURN relays behind a live call so your app only builds the interface. What it is, how a call flows through it, what VideoSDK, Daily, Agora, Twilio, and Amazon Chime charge per participant minute, and a ten-point checklist for choosing one.

Integrate a video conferencing API in six steps with VideoSDK: create a room, mint a scoped JWT on your server, join from the client, render participant streams, wire mute and screen share, then clean up.

A user on a 500 Mbps connection reports a laggy call and support tells them to upgrade. It does not help, because bandwidth was never the problem. Video quality is decided at three independent layers: network, compression, and packaging. Here is what each controls, and how to tell them apart.
