Yesterday, Jean-Baptiste Kempf, VideoLAN president announced dav1d 0.1.0. dav1d is an AV1 decoder from VideoLAN, the same company that offers the popular VLC Media Player. dav1d was first presented in Video Developer Days 2018.
The first usable version of dav1d, dav1d 0.1.0 is dubbed as Gazelle. In this release users can use the API, ship the decoder, and expect to receive some support from the developers.
Since the initial launch of dav1d in September 2018 there has been a lot of work done on it:
Biggest advantage dav1d has is its high scalability. The performance gets much better as the number of threads goes up. Results from a 32-core AMD Epyc processor:

As you can see. aomdec caps out at 8 threads while dav1d keeps on scaling with higher number of threads.
Performance on smartphone processors:

On multiple cores, 1080p 30fps can be decoded by most high-end chips released in the past two years. On an Apple A12X, 1440p at 60fps and 4K at 30fps is possible!
