Dav1d 1.2.1 Released With More Performance Optimizations

Dav1d 1.2.1 was released and while the version number may not be significant, it does have some useful performance optimizations and other tuning for this CPU-based open-source AV1 video decoder.

The dav1d 1.2.1 release adds more SIMD capabilities, various fixes, reduced memory consumption, fixes a threading race condition, and more.

Dav1d release manager Jean-Baptiste Kempf explained of dav1d 1.2.1 that the optimizations for z1/z2/z3 tools are very useful for AVIF (AV1 image support), ARM64 NEON optimizations are now all complete, and the AVX-512 code has become "quite advanced now" and performing much better than AVX2. However, the AVX-512 code is still not considered complete yet and more performance tuning for AVX-512 is still expected to come.
