Surprised even MPEG-5 EVC made it. Unfortunately the VVC Decoder didn't quite make it ( Edit : Officially ) . I guess we will have to wait until version 7.1. Still waiting for x266.

View on HN

The built-in VVC decoder is dreadfully slow (a ton of optimizations are missing), VVdec is at least 2-3 times faster on anything having AVX2/SSE4.

If you really want to give VVC a try, better stay with version 6.1.1 as it's the last one which has patches for enabling VVdec. You won't be able to apply them to version 7.0/git master:

VVC decoder is available, but it's flagged as experimental, so you have to prefix `-strict experimental` before the VVC input `-i`.

Thanks Yes I meant officially. Was hoping the we could set stage for VVC little earlier. I know VVC is not popular on HN or literally anywhere on Internet but I do hope to see it moving forward instead of something like MPEG-5 EVC which is somewhat dead in the water.

I don't know that having so many codecs is a good thing unless they really add something. How does it compare to av1 (which I was under the impression is coming to be the natural successor of hevc, with hardware support)?

Comparing to AV1, VVC / H.266 is expected to offer 20-30% reduction in Bit-Rate with similar quality at similar level of computational complexity. And it is already deployed and used in real world in China and India. I believe Brazil are looking to use it as their next generation codec for broadcasting along with LCEVC.

Here's the Brazil website.

And their video codec testing.

And ATSC 3.0 will also be using VVC.

VVC is marked as experimental as fuzzing continues on it.
