AV1 is a video codec developed by Google and Netflix, etc., and was officially released in March 2018. It is said that streaming of UHD-quality movies such as 4K 60p is also widespread by adopting AV1 that boasts a higher compression ratio than conventional VP9 and HEVC .

AV1 decoding is enabled by default for Firefox 67 official version, 32-bit and 64-bit versions of Windows, macOS and Linux. The installed AV1 decoder is dav1d developed by VideoLAN , the developer of VLC Player. According to Egge, dav1d fits into a code size that is more than 30% smaller than the VP9 decoder and nearly 50% smaller than the H.264 / MPEG-4 AVC decoder.
Also, dav1d is 2 to 5 times faster than the 'libaom' decoder by Alliance for Open Media. Mr. Egge evaluates dav1d as 'the world's fastest AV1 decoder,' and 'using dav1d to show higher performance and efficiency enables smooth movie playback on the browser while using less CPU.' It says. In addition, Egge revealed that Mozilla is collaborating with the non-profit organization Xiph.Org to develop an open source proprietary AV1 encoder called ' rav1e '.
According to usage statistics of Firefox 67 Beta, the percentage of movies played on Firefox 67 Beta that of the AV1 codec is 0.85% in February 2019, 3% in March of the same year, and April 2019 It is 11.8%, indicating that the spread of the AV1 codec is accelerating on the Internet.

It is reported that the performance has been improved by the end of May 2019 as open source development adds many new features.
