AV2 saves 25% bandwidth at the cost of 5x more decoding complexity.

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.
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
