    Phoronix: AMD Posts VP9 VA-API Video Acceleration For Gallium3D

    Hitting the Mesa mailing list today from AMD developers are a set of twenty-two patches providing VP9 video acceleration support via the Gallium3D VA-API state tracker...

    Is this just for decoding, or for encoding as well?

      I really hope Intel + AMD can get AV1 hardware support into their 2019 Ice Lake / Ryzen 2 / Navi chips considering it functionally supersedes vp9. All of them are supposed to be major architectural jumps, plus a die shrink, so they will be around a long time. AV1s long term success will in large part depend on there being comprehensive hardware support soon.

        Is VCE 4.0 the least interesting video encoding ASIC?

          Great. What about AV1?

          And is it using shaders implementation or hardware decoder?

            zanny i don't think AV1 is ready for hardware support yet.
            decoding might work but encoding still have a long way to go.

            About VP9 amd continues to deliver on linux.
            I only waits for an ryzen mobile that fits my needs.

              Right now, what AV1 needs first and foremost is an encoder. libaom is unusable. No one will go about making AV1 videos if encoding is measured in minutes-per-frame.

              Waaaaaay too soon for AV1 hardware decoders.

              Very rarely does Linux get shader-based decoders (there's basically just intel-hybrid-driver, but even that one only exists because Google commissioned it, likely for Chromebooks), this is using the the full fixed-function ASIC decoder as found on Raven Ridge (currently, the only AMD hardware that has one).

                  decode only, for now there's no amd hardware with vp9 encode

                    nice, this will be useful once browsers start using vaapi as vp9 is youtube most used codec
