@andrew84 Weird. Then one more guess. Chrome and Edge use proprietary codecs for h.264, while pure Chromium, Opera and Vivaldi do not, I know that for sure. Can you test your CPU load problem for h.264 for example in Vivaldi 4.3? (Portable mode can be selected in the installer, similar to Opera).

@andrew84 Then perhaps this is a problem of new versions of browsers on the chromium engine, but compiled without their own proprietary codecs? Such browsers use system codecs. (If you self-compile the source code for chromium, you can enable this feature, but I think that browser developers should have a license).
But this is something specific, related to your system or hardware. On Win 7x64, I could not reproduce your problem. The CPU load when watching this example video in h.264 with h264ify is about the same in any version of Opera, Chrome and Vivaldi. Edge is slightly less than others, but in any case, the CPU load is small. -

@johnd78 There's no way trying fixing it locally (install/reinstall/update system codecs, 3rd party codecs, copy something from O78 installation and paste into O81 directory or similar way)?

In the case of the O78, definitely not. Honestly, I don't know what is wrong with the system codecs in your case.

@andrew84 Dev is curious. Could you please provide full
opera://media-internallogs for both Opera 78 and 81/82 with the h264ify so that you get the h.264 video and the high cpu usage?Also, please try
--disable-features=D3D11VideoDecoderon the command-line. to see if that makes a difference. (I know you already tried changingopera://flags/#use-angleto not use D3D11, but try this specifically.)If not, try
--enable-features=D3D11VideoDecoderIgnoreWorkarounds. -

Hi, I'll check logs also but it seems that this switch helped, and I have normal CPU usage.
*Just in case, I tried to change the #angle-flag to D3D9 one more time in Experiments, but it doesn't affect.
--enable-features=D3D11VideoDecoderIgnoreWorkarounds doesn't help**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/t5smwI 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 = D3D11VideoDecodereverything 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 = D3D11VideoDecoderswitch. Regardless of the h264ify extension. -

@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.
