    Oh, I see! Thanks for clearing it up! That's much nicer than the parallel reality I was briefly living in
    I wouldn't even be all that upset myself, since it would help push av1 and vp9 even more

    Sure enough you can use an old version of mesa, or patch the new code, but that's very different from flipping a flag when compiling the new code.
    ah I see, no you got it backwards, it means that mesa introduced the capability to build mesa without needing to enable those codecs, before if you enabled vaapi you had to enable all codecs such as avc and hevc, so what is being said here is that you now have the ability to build mesa with vaapi without needing said codecs.

    now you specify something like -Dvideo-codecs h264enc h265dec etc.

    what are you talking about here? you can still enable the codecs in git...

    Support for building Mesa with select video codecs disabled out of software patent concerns.
    Sure enough you can use an old version of mesa, or patch the new code, but that's very different from flipping a flag when compiling the current version of the code. And the way this is written isn't pointing towards just a new compile flag with default state off.

    it's horrible to see how patent law can be so pernicious and antagonic to technological advancement and adoption, and it's also a bit scary that this has been in there until now and only now did they wake up to such a big risk being taken...

    also it's a bit ironic that Nvidia now has a VA-API over NVENC compatibility layer at the same time that so many patent-encumbered codecs are ripped off of opensource drivers...

    Yes, thanks (I konw ;-) )
    All fine for some days.
    But I haven't had time for earlier posting.
    More to come.

    See here, too:

    Check if the mesa build you use adds
    Code:
    -D video-codecs=vc1dec,h264dec,h264enc,h265dec,h265enc
    to its meson command.

    See https://gitlab.freedesktop.org/mesa/...29c163e42c3600 and https://bugs.archlinux.org/task/74615 for more info.

    Radeon(SI)
    Can anyone please verify if most VA and VDPAU hardware accelerated modes didn't work for you any longer, too?

    Polaris 20, here.
    See it for several months.
    Due to LLVM 14/15 (git) and other toolchain things I haven't bisected it, yet.
    I've currently no idea which commit could be the culprit.
