Dav1d is already the most performant and leading AV1 software decoder we have seen while out today is v0.8.2 that should speed-up the video decode process even more on modern x86/x86_64 and ARM hardware.

While dav1d 0.8.2 is "just a point release", it does pack some interesting performance optimizations for today's hardware. On the ARM front there are ARM32 optimizations to speed up loop restoration and for other operations. ARM64 has also rewritten the wiener functions, and improved IPRED and WARP, among other work.

On the x86 front there are optimizations for CDEF_filter and wiener in 10/12-bit, rewritten SGR AVX2 Assembly, and improved MSAC speed on SSE2+ hardware.

The dav1d update has also sped up coefficient decoding, seeking and pausing was added to the player, and other speed improvements across all platforms.

Dav1d 0.8.2 can be downloaded from VideoLAN.org. Via dav1d on OpenBenchmarking.org are many CPU metrics for this AV1 decoder while the test profile will be updated shortly for the new 0.8.2 release.
