- 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.

- 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).

- Mostly ASM for performance critical paths is a pattern that never gets old. The VideoLAN team did the same with dav1d and it paid off. Curious how much of dav2d ends up staying C as AV2 matures.

- Some dude at videolan be like, I've have a cool name idea
- 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
- is there any understanding of how big of an improvment av2 will be over av1?
- With the first RVA23 boards shipping this month, I find it a mistake to still focus on legacy ISAs like x86 or ARM rather than what will be dominant by the time AV2 is deployed.
- 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" ?
- Nice.
What's the current state of of Dolby trying too attack AV1 ecosystem (Snapchat more specifically)? I hope there is an organized fight back by AOM against these trolls.
- 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.

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

- 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.
