Dav2d doesn't have the same nice ring to it. I hope there's someone with a decent repo-name punning skill who'll contribute before that.

avi2ude? av2go?

It was difficult to find a nice name, with av2 :(

It works in French d2vid (Deuvid)

rav2d works imo — https://github.com/stukenov/rav2d. rust port, same vibe as rav1d→dav1d.

At least it's not D4vd.

2av2quit?

I like it - not as punny as the first but pretty straightforward.

daviid - or trim to davii and pronounce it "davey". But tbh I quite like dav2d.
