  • Rav1e Achieves Another ~20% Speed-Up For Rust-Based AV1 Video Encoding

    Rav1e's weekly-ish pre-releases for this Rust-written AV1 encoder have been focusing a lot on better performance via hand-written x86 Assembly, making use of SIMD extensions, and other fine tuning of their encoder. With this newest pre-release, another ~20% speed-up was obtained.  Today's rav1e p20191215 build is around 20% faster thanks to porting more Assembly optimizations from the dav1d AV1 decoder over to rav1e. There is also now forward-transform SIMD support and simplifications/refactoring to the motion estimation and scene change code.
