Dav1d 0.9.0 ‘Golden Eagle’:

0.9.0 is a major version of dav1d, adding notably 10b acceleration on x64.

Details:

• x86 (64bit) AVX2 implementation of most 10b/12b functions, which should provide a large boost for high-bitdepth decoding on modern x86 computers and servers.
• ARM64 neon implementation of FilmGrain (4:2:0/4:2:2/4:4:4 8bit)
• New API to signal events happening during the decoding process

Dav1d 0.9.1 ‘Golden Eagle’:

0.9.1 is a middle-size revision of dav1d, adding notably 10b acceleration for SSSE3:

• Film grain NEON for fguv 10/12b, fgy/fguv 8b and fgy/fguv 10/12 arm32
• Fixes for filmgrain on ARM

Dav1d 1.0.0 ‘Peregrine falcon’:

1.0.0 is a major release of dav1d, adding important features and bug fixes.

It notably changes, in an important way, the way threading works, by adding an automatic thread management.

It also adds support for AVX-512 acceleration, and adds speedups to existing x86 code (from SSE2 to AVX2).

1.0.0 adds new grain API to ease acceleration on the GPU, and adds an API call to get information of which frame failed to decode, in error cases.

Finally, 1.0.0 fixes numerous small bugs that were reported since the beginning of the project to have a proper release.
