    What benefits does this have?

      You mean, like, always? Dedicated HW is of course more power efficient. That's the point. What were you trying to say?

      I can watch 1080p youtube video, yes, but not without burning so much more watts than necessary. This is such a shame to contribute to climate warming. I guess that, collectively, linux users on youtube burn Gigawatts/H every day for no real reason other than "we have to focus our efforts on windows and the videos are playing on today's CPUs anyways"

        Edit: https://github.com/Igalia/chromium/t...ne-wayland-dev seems to be upstreamed and https://chromium.googlesource.com/ch...ne_overview.md shows there is experimental Wayland since m57
        My understanding is it's largely because it's hitting quite a lot of the project components many of which clearly aren't equipped to deal with reviewing external contributions in promptly manner.

          This is really great! I hope they eventually end up using EGL also in X11 codepath.

            The DMABUF work is a perquisite for hardware video decoding. Chrome also uses it for it's implementation.

              I do not mean always.

              I am measuring a saving of about 4 Watts at the outlet ("mplayer -vo vdpau" vs "mplayer -vo x11") when playing 1080p 60Hz H264 video.

Firefox, and Chrome, use the GPU more and more for the internet browsing, but on Linux they do not use the GPU for the video decoding, one of the most important thing in the internet world. Maybe their programmers are not good enough and do not know how to do it. Please, can someone help them? It's funny.
                With the move to less patent-encumbered codecs like VP9 and AV1 it's less common that you actually have fixed function hardware that supports decoding your codec.

                  Maybe. However what this points out to me is the value in a good GPU. Off loading to the GPU should increase performance on most systems. This is also why I try to turn people to systems with a semi decent GPU even if they aren’t gamers.

                    Nowadays 3 CPU cores with AVX2 are able to decode any video type up to 4K 10-bit HDR 60Hz, the CPU might only have issues handling 8K videos
                    My 6700k is well overchallanged with 4k 60fps HEVC 10 bit high bitrate.

                      The Wayland support is shaping up nicely for Firefox. The last months there have been very much progress. Now you can run Firefox on Wayland it works pretty well, even though it doesn't work perfectly yet.
