Modern & secure adaptive streaming on the Web
summary
Explains how fragmented MP4 + DASH + MSE give precise control over which segments the player requests, shows encoding with ffmpeg into five bitrate ladders and fixed ~2s segments (48‑frame GOP) to avoid glitches, uses Bento4 mp4dash to produce per‑representation folders and an MPD, demonstrates runtime bitrate switches fetching segments from different folders, and walks through encryption using Encrypted Media Extensions (EME), PSSH atoms, license fetch/update to the CDM with a working encrypted playback demo.
