What does "complexity" mean here? Computation required?

dav1d is the av1 decoder and it’s an insane feat of engineering. Written in assembly, it even eschews the normal c calling convention to get even better performance.

		The normal C calling convention is really only for cross-binary calls (e.g. between shared libraries). If you're not doing that you can ignore it; it's not a weird thing to do. It would be odd to strictly follow it in assembly and I assume compilers don't either.

Yes, much higher computation required to encode it, and decode it, both.

		He only mentioned decode complexity. Would be interesting to know the average encode complexity compared to AV1.

Yes
