black screen video
On some websites black screen instead of video (sound works well). For example: http://www.ceskatelevize.cz/sport/zive-vysilani/.

Intel HD + AMD have some issues.
Try disable hardware acceleration at vivaldi://chrome/settings/search#hardw
If that does not help then disable accelerated video at vivaldi://flags/#disable-accelerated-video-decode
@Gwen-Dragon Yeah, and one of the two will likely help. The real issue is that disabling hardware acceleration is no longtime solution. Hardware acceleration is in the browser for a reason.
I would try just the igpu and if it's blacklisted, set the flag to enable it.
@Gwen-Dragon Thanks, I've tried to disable accelerated video and video is working now, but CPU consumption is really huge. Is it some way to set some filter to disable video acceleration only for some websites? (For example YouTube works fine with acceleration).
@luetage Sorry I don't understand, what you mean: "I would try just the igpu and if it's blacklisted, set the flag to enable it."
Did you mean this flag: chrome://flags/#ignore-gpu-blacklist ? I've tried to set up it, but video is still not working.
@coksack No, there isn't, and of course cpu peaks, because the workload that should be done by your gpu is now handled by your cpu. Either try and get your gpu to work, exchange your gpu for something compatible, or, and I hate to say it, change browser.
@coksack What gpu do you have enabled, the igpu or the dedicated one? You should try both with hardware acceleration enabled and no flags set.

Yes, hat is the problem with software rendering and decoding: CPU has to work much more as it has to calculate many graphical routines.

No, unfortunately not.
Can you disable the internal Intel GPU in BIOS or set the priority to AMD?
That may help with enabling hardware acceleration, i guess.
Well, I win. I've found where assign application to graphics card. So when I set AMD, video doesn't work, but when I set Intel video acceleration it works (true is, that there is sometime some flicker in video, but isn't so bad). I hope, that integrated graphics has enough power to accelerate whole browser. Maybe I'll try disable intel in bios later whether it helps. Thanks a lot for help.
but when I set Intel video acceleration it works (true is, that there is sometime some flicker in video, but isn't so bad).
May be you canchange VSync synchronisation, that could reduce flicker with Intel GPU.
That helped Linux users in the past, may work on Windows, too.
