Back of the class you go.

> AV2 provides enhanced support for AR/VR applications, split-screen delivery of multiple programs, improved handling of screen content, and an ability to operate over a wider visual quality range.

TFA says that the test was done on an Apple laptop and the decoding was done on the CPU, so not using any special hardware support.

The reference AV2 implementation uses architecture-specific SIMD instructions on x86-64, Aarch64 and IBM POWER.

So in this test it has used the ARM vector ISA (Neon), written with intrinsics in the C language, as it can be seen in the source files:

However, during the last few days there have been many news about the owners of the HEVC patents and about the owners of the older H.264 patents making great efforts to extort much more money from the users of HEVC or of H.264.

This has made recently some big vendors of computers to disable the hardware HEVC codecs in the computers that they are selling, instead of paying increased royalties.

At least the H.264 patents have already expired in all countries, except in less than a handful of countries, including USA, so the use of H.264 is safe wherever the patents are no longer valid (but not in USA, where the H.264 patents will remain valid for less than a couple of years).

On the other hand, for HEVC the patents will remain valid for many years, so using it will not be safe even for those who pay royalties, as the royalties may be increased at any time, as shown by the recent history.

Therefore it is wise to avoid HEVC (and its VVC successor) and prefer alternative codecs.
