CHUNKY MONKEY
summary
Claims that chunked-encoded CMAF delivers practical low-latency OTT at scale and shows concrete numbers: playback can hit around 500 milliseconds at the edge down from multi‑second legacy delays while using standard CDNs and HTTP chunked transfer. Demonstrations use ffmpeg + Akamai broadcaster pushing to CDN and an open-source dash.js player, show compatibility with legacy players, CDN cacheability, a modest audio overhead (~40%) and working live demos.
