Pretty much all of them. Encode complexity for most codecs is way higher than decode complexity (on purpose).
This has been an issue with AV1, it's got relatively high decode complexity and there's not a lot of hardware acceleration available. The encode complexity is fantastic though and is very slow even on very powerful hardware, less than 1fps so ~30 hours to encode a one hour video. Even Intel's highly optimized AV1 encoder can't break 10fps (three hours to encode an hour of video) while their h.265 encoder can hit 300fps on the same hardware.
