Scaling AV1 End-to-End Delivery at Meta
summary
Meta describes an end-to-end AV1 rollout for Reels using SVT-AV1 with 13 presets and a two-stage hybrid hardware+software pipeline: first-stage fast HW/AVC pass to build a convex-hull from ~35 RD points (7 resolutions × 5 CRFs), then second-stage software AV1 encodes chosen points. Decoder strategy uses dav1d app-level decoder on iOS/Android with device microbenchmarks to bucket phones. Claims: ~30% coding-efficiency vs VP9/H.264, ~65% bitrate vs AVC and ~48% vs VP9 on examples, 12% avg bitrate drop and fast watch-time adoption on iPhone.
