@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.

@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.

l33t4opera last edited by l33t4operaHi @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"). -

@johnd78 So the correct decoder is VDAVideoDecoder for the h.264?
If I'm getting it right from the log, in O82 (in my case) is used WMFVideoDecoder which is also incorrect? -

@l33t4opera you can check the logs and screenshot.

@andrew84 For H.264 hardware decoding, "VDAVideoDecoder" is used. "FFmpegVideoDecoder" for Chrome or "WMFVideoDecoder" for Opera means no hardware acceleration for video decoding.

So in Chrome you also have problems with hardware H.264 decoding on the desktop, the load on the CPU in Chrome in your screenshot is too high. Try to use the switch--disable-features=D3D11VideoDecoderin Chrome, it is possible that the CPU load will be reduced to the Edge level. The case with Edge is special, there are significant differences in the browser code from chromium.Bottom line: code changes on Chromium 93 broke the hardware H.264 decoding on some Intel integrated graphics cards, this is still not fixed in Chromium 97.
As a workaround, you can use the--disable-features=D3D11VideoDecoderswitch.
