    Those applications work on many OS, and they will usually use HW codecs. The same exact ones mentioned previously which you never bothered to check.

    When talking about a processor and HW acceleration, it's not limited to VAAPI btw, even if you happened to name drop it somehow.

      You have no idea what you're talking about so refrain from faking it. You are on an forum where people actually know what they're talking about.

        Zoom: https://support.zoom.us/hc/en-us/art...bile_site=true
        Skype on Windows uses native APIs that are connected to codecs provided by GPU vendors occasionally.
        Chrome uses the same APIs for HW support on Windows and equivalent ones on macOS. Chrome uses VAAPI on ChromeOS hardware when it's capable.

          Zoom has it's own video decoder / encoder path by default.
          Skype has it's own video decoder / encoder path by default.
          Chrome is the only one that uses GPU decode acceleration only and it uses it's own video encode path.

          You have to jump through a dozen loops to get your media players to use the right codec path that uses the GPU decoder. Pretty much nothing uses the GPU encoder besides heavily optimized applications like Twitch that only use NVENC.

          On Linux, the same thing with V4L2, VAAPI, VDPAU for both the encoder and decoder side.

            What do you use? Windows Media Player? lol

              is this aisc based or gpu based decoder?

              both are entirely different thing
              asic offers, decoding with powersaving
              gup offers decoding at thecost powersaving(though better than cpu)

                H266 is DOA

                  I only meant: unreleased hardware lacks support, it will be a while till we see the next generation.

                    It's not. All content providers will be all over lowered bit rates

                      It seems to me that AV1 repeats the mistakes of VP8/VP9, by not proving their standard with multiple software/hardware implementations before finalizing it (with conformance tests suites). See the sorry state of HW acceleration in Linux, with AVC/HEVC you can be pretty sure HW will adhere to standards and not randomly crash.

                      I mean I hope EVC succeeds, but why?
