> It really is the state of the art Video Codec, at a decoding complexity that is quite manageable. ( Lower than AV1 )

I am afraid this has not been substantiated by any of the public decoder demonstrations I've seen. Please see the most recent VVC technical update presented at the MC-IF meeting on March 2nd of this year:

https://a7dce6fd-e8f0-45f7-b0b0-255c5c9a28e1.filesusr.com/ug...

On slide 10 is a graph of VVC performance showing the VTM (VVC) decoder at 2.0x the complexity of HM (HEVC). On slide 12, the Ittiam production decoder boasts 1920x1080 @ 24fps on a 4-core Cortex A75 @ 2.5GHz.

Compare that with this recent study of dav1d (AV1) decoder complexity on a broad set of mobile SOCs, where 1920x1080 @ 24fps was easily reached by a Google Pixel 1 from 2016! Using just the two LITTLE cores! Even higher frame rates were achieved with more modern devices:

Full disclosure, I contribute to the dav1d project and performed this study.

Yes. But I think it should be noted the HM and VTM are reference encoder and decoder, they are not meant to be used for production nor in any way optimised.

But dav1d is a truly amazing pieces of work!

Sure, but my comparison was to the Ittiam production decoder.
