      @andrew84 said in Opera 81.0.4196.0 developer update:

      The log from 82 is need with --disable-features=D3D11VideoDecoder switch or without it?

      Without. But, you could show the log with it too just for good measure.

        O82 log https://textuploader.com/t5sq5
        O82 + switch log https://textuploader.com/t5sqr

        *I can also add logs from laptop a bit later, if that matters. Laptop has i3 3110m which is Ivy Bridge family and also is mentioned in opera://gpu report

          logs from laptop
          O78(Portable) https://textuploader.com/t5smn
          O82 https://textuploader.com/t5smw

          I also noticed that comparing to O78 in O82 there's CDM tab in media-internals.
          And I noticed that on laptop there's win_x86 in the description and on Desktop PC win _x64 (both PCs are on win 8.1x64)

            @andrew84 For the Opera that shows x86, I'd double-check in the task manager to make sure it's not a 32-bit Opera process. Besides that, not sure.

              @burnout426 Sorry, my bad.
              Opera developer process was 32b bit for some reason on laptop. I didn't notice. But it was installed in Program files (not in Program files x86) and I always use autoupdate.

                @andrew84 Everything is clear in the logs.
                Judging by the desktop logs, O82 uses WMFVideoDecoder instead of VDAVideoDecoder for D3D11 due to the "Failed to initialize D3D11VideoDecoder" error. In this case, there is no hardware acceleration for the video.
                With --disable-features = D3D11VideoDecoder everything is fine, VDAVideoDecoder is applied.
                The laptop successfully uses VDAVideoDecoder with D3D11VideoDecoder.
                In the Chromium bugtracker, I saw a mention of a similar problem. It looks like some chromium code changes may cause falling back from HW encoder to SW openh264 encoder for Intel graphics. But this is a side effect of solving another bug.
                I did not see this problem directly in the chromium bugtracker.

                  @johnd78 it's safe to use this switch --disable-features = D3D11VideoDecoder as a temporary solution or there are some limitations in this case? Or it's the same as without the h264ify extension?

                    @andrew84 It is absolutely safe to use the --disable-features = D3D11VideoDecoder switch. Regardless of the h264ify extension.

                      @johnd78 ok, thanks. I'll note this solution but I'll stay on 78 so far.

                        @andrew84 It is still not clear why you have no problems in Chrome and Edge. The bug tracker mentioned that the latest codecs are added to the Chrome builds.

                          @andrew84, dev would like you do produce a media-internals log in Chrome Canary (with h264ify and the same video). Thanks.

                            @andrew84 Please uninstall it, delete the install folder, install the 64-bit version, and test again (if you haven't already) to see if there's any difference.

                              @andrew84 Found a recent thread on the ixbt forum (Russian). Very similar to your problem with hardware H.264 decoding, I think related directly.

                                @burnout426 Yes, I already did it and the result is the same (plays fine/acceptable on laptop)

                                    @johnd78 Yes, very similar.
                                    The only difference is that it works fine on laptop here in both Chrome(I checked in Beta) and in Opera.
                                    *on Desktop I have the issue in Vivaldi and in Opera.

                                      @andrew84 In your case, the difference is in the video card. For desktop g3450 - Intel HD Graphics. For laptop i3 3110m - Intel HD Graphics 4000.

                                        @johnd78 I can add a remark here. When I say 'no issues' on Chrome/Edge or on laptop I mean that there's no such heavy CPU overload (task manager shows 100% all the time -straight line on top) and continuous video freezes.
                                        Maybe, technically the issue is also on Chrome/Edge or on laptop (wrong decoder is in use or similar problem) but just the overload is not so heavy. I'm not very familiar with all this video decoding stuff.

                                          @andrew84 Looked at Chrome Canary logs, it uses FFmpegVideoDecoder for D3D11 instead of VDAVideoDecoder. No idea why or how.

                                            Hi @johnd78, the "FFmpegVideoDecoder" means there's no HW acceleration for video decoding.
                                            Did you check what it says about it under "opera:gpu"?
                                            When a video is replayed, what codec it uses (you can check it on YT under "Stats for nerds").
