dav1d 0.1.0 'Gazelle', the fast and small AV1 decoder This is the first release of dav1d, the fast and small AV1 decoder, codename 'Gazelle'. It supports all AV1 features and all bitdepths, from 8 to 12bits. It is very fast compared to other AV1 decoders on AVX-2 processors. It has already SSSE3 and NEON code for other processors, and will get a lot more of those optimizations in the future.

dav1d is a new AV1 cross-platform decoder, open-source, and focused on speed and correctness.
The canonical repository URL for this repo is https://code.videolan.org/videolan/dav1d
This project is partially funded by the Alliance for Open Media/AOM.
The goal of this project is to provide a decoder for most platforms, and achieve the highest speed possible to overcome the lack of AV1 hardware decoder.
It aims to support all features from AV1, including all subsampling and bit-depth parameters.
In the future, this project will host simple tools or simple wrappings (like, for example, an MFT transform).
dav1d is released under a very liberal license, a contrario from the other VideoLAN projects, so that it can be embedded anywhere, including non-open-source software; or even drivers, for hybrid decoders.
The reasoning behind this decision is the same as for libvorbis, RMS on vorbis.
The plan is the folllowing:
By the end of 2018, we hope to have a completely usable version that will be faster than any other software open source implementation.
Currently, we are looking for help from:
Our contributions guidelines are strict. We want to build a coherent codebase to simplify maintenance and achieve the highest possible speed.
Notably, the codebase is in pure C and asm.
We are on IRC, on the #dav1d channel on Freenode.
