    Sadly yes.
    The worst has already happened, we pay for every new phone media box and gpu since they all include HEVC now.
    It is like a cancer that has started and won't let us go any more

      Isn't AV1 based on what would have been VP10 code and not VP9?

        VP9 as base + various experiments which you can switch on when compiling.. these are coding tools from VP10, daala and thor

            Hmmm, are you sure? I keep reading things such as these:

            The initial AV1 implementation will incorporate some features of Daala and Thor, but most of the code will come from VP10, which was scheduled to ship by the end of 2016.

              Correct link (has likely been updated and received a new ID):

                That's the same as I said considering VP10 is VP9 + some new experiments. Most of the experiments in AV1 are from VP10 or exactly nextgenv2 branch in libvpx, and most of this code was merged to the aom repository not so long ago (December?). If you don't enable any experiments when compiling aomenc the quality is nearly the same as with VP9.

                    Almost feels like they're using new codecs to drive hardware sales. Oh, your phone/tablet/laptop/video card/device doesn't support the new XYZ codec? Guess you'll have to buy a new one. If you don't, your CPU will be pegged at 100% since you don't have hardware decoding.

                      Since modern CPUs absolutely must contain proprietary closed source blobs it might be nice if the hardware-accelerated video decoding logic could also be updated to include some level of support for newer codecs (like the AV1 here), a la Transmeta's upgradeable Code Morphing system or similar.

                      It would, eventually, encourage faster adoptation of the newer and supposedly more efficient codecs and a billion CPUs saving a watt here and another there would help keep a few blobs of coal where it belongs, underground.
