@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. -

@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 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. -

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"). -

@l33t4opera you can check the logs and screenshot.
