Video streaming on the web: Live and recorded video streaming

Explains that real streaming breaks video into 4–10 second chunks with an m3u8 manifest and TS segments so players can adapt bitrate and seek, contrasts that with a single-file video tag which is fine for <~1.5 minutes but not responsive. Shows a browser pipeline using getUserMedia → canvas → WebSocket → Node → FFmpeg transmux to RTMP then HLS delivery, uses api.video for upload/transcode (short demo encodes in ~5s), demos work but true live was pre-recorded for reliability.
