      Why doesn't GPU video decoding work in Opera?
      Back in april it only worked in Microsoft Edge, all other browsers would make my CPU shit itself.
      But now i've noticed that it works in Google Chrome as well, so why isn't it working in Opera yet?

      An example video is this one: UNIGINE Superposition Benchmark [8K 60 FPS]

      When playing the video at 8K 60FPS, Opera makes the CPU usage go up to 100% and the video is choppy and stutters, and GPU video decoding sits at 0%: Opera

      But when i play the video in Microsoft Edge or Google chrome the CPU usage is a lot lower, 10-30% in Edge and 20-40% in Chrome, and now GPU video decoding sits at a steady 80%: Edge/Chrome

        I just checked on Opera 49 and on gtx 1050 the decoding works as it should. All settings are default and without extensions.

        But on my old notebook with a Pentium 987 for 1.5 GHz the opera really consumes much more CPU than chrome. We have to install h264iify.

          @tempale The same codec is used in Opera and in Edge when watching YouTube videos?

            So you're on Opera Developer 49?
            I'm on 48.0.2685.52, maybe it'll work when non-developer hits 49? Or do you think something else may be the problem?

              It says "vp9 (272) / opus (251)" in Opera, Chrome and Edge.

                @huddinge, Checked on the opera 48 - everything works as it should.

                Check the parameter opera://flags/?search=hard#disable-accelerated-video-decodee ("Hardware-accelerated video decode" it must be enabled)

                    It's working now o.o
                    What i for some stupid reason had to do was first untick this, restart the browser, then tick it again, and restart the browser once again, and then it was working after that.
                    "have you tried turning it off and back on again" pfft stupid
