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)
At least it's not D4vd.
2av2quit?
daviid - or trim to davii and pronounce it "davey". But tbh I quite like dav2d.
I like it - not as punny as the first but pretty straightforward.
