dav1d 0.7.0 'Frigatebird' the fast and lean AV1 decoder This is a major update of the dav1d, the fast and lean AV1 decoder, codename 'Frigatebird'. This release improves, once again, the speed on all platforms. A rewrite of refmv made an important speed boost on x86 while reducing RAM usage. It should improve the speed on every platform. A large number of assembly optimizations went for ARM64 for 8/10/12bit, a few for x86, notably for film grain and AVX-512 optimizations for CDEF.
