Project description:

  dav2d is the fastest AV2 decoder on all platforms :)
  Targeted to be small, portable and very fast.
If you're out of the loop like me:

  AV2 is the next-generation video coding specification from the Alliance for Open Media (AOMedia). Building on the foundation of AV1, AV2 is engineered to provide superior compression efficiency, enabling high-quality video delivery at significantly lower bitrates. It is optimized for the evolving demands of streaming, broadcasting, and real-time video conferencing.

Not on topic, but wow the internet has very quickly devolved into: click -> "making sure you're not a bot", click -> "making sure you're a human", click -> "COOKIES COOKIES COOKIES", click -> "cloudflare something something"

AV2 video codec delivers 30% lower bitrate than AV1, final spec due in late 2025 (videocardz.com) | Oct 2025 | 277 points | 223 comments | https://news.ycombinator.com/item?id=45547537

Glorious. Really looking forward to seeing how much better than AV1 it actually turns out to be. It's a shame it'll take a while before we'll have a decent encoder (it took an annoyingly long time until SVT-AV1 was usable).

is there any understanding of how big of an improvment av2 will be over av1?

off topic, but related to the recent github alternative discussion:

Wow, this gitlab instance looked so much cleaner/simpler and less clunky than my past experiences! Also loaded really fast on first page load as well as subsequent actions

maybe not great naming. Sounds very similar to the rapper D4vd, who was just arrested for murdering a 14 year old girl

Just recently noticed this got posted to deb-multimedia, although I think there is a typo in the package description....

https://www.deb-multimedia.org/dists/unstable/main/binary-am...

... it says "fast and small AV1 video stream decoder"

... should probably be "AV2" ?

I would even remove the C code and lower the usage of the assembler pre-processor to a basic C pre-processor.

Happy, AV2 decoding already here.

:)

I wonder if the author is a Dave2D fan?

We must not continue to develop media codecs in memory unsafe languages. Small, auditable sections can opt-out perhaps, but choosing default-unsafe for this type of software is close to professional negligence.
