Mozilla and AV1
summary
AV1 consolidates ideas from Daala, Thor and VP9 into a royalty‑free codec claiming roughly 30% compression gains over HEVC on early tests, with the finalized bitstream landed this year. Key merged tools include chroma-from-luma prediction and a fused constrained directional enhancement filter that reduces artifacts. Mozilla contributes an Emscripten-compiled analyzer running in the browser to compare encoded streams. Current encoders run ~200× slower than VP9, decoding is in Firefox nightly and hardware support is forthcoming, promising large royalty savings.
