AV1 Update
summary
AV1 reaches a soft bitstream freeze and ships high-level syntax, sequence and frame headers, tile groups, WebM/Matroska and ISO BMFF packing plus RTP for real‑time, and shows concrete tools: chroma-from-luma yields ~6% on gaming and up to 20% on Minecraft, references expand to seven frames, wedge codebooks, global/warped motion, CDEF plus loop restoration. Encoder is about 200× slower than VP9 today while decoder is ~1.5× slower, and objective metrics show roughly 25%–35% bitrate reduction versus current baselines; demos run in Firefox nightly and VLC.
