Opera 77 - no more hardware video decode?

[nfm886]

Just notice there is no more hardware video decode flag in opera://flags.
Did a step-by-step guide how to enable HVA with chromium-flags.conf but… it does not works.

[Yochanan]

it’s now --enable-features=VaapiVideoDecoder instead of --enable-accelerated-video-decode. See Chromium - ArchWiki

[nfm886]

Yes.
I have those flags:

–ignore-gpu-blocklist
–enable-gpu-rasterization
–enable-zero-copy
–enable-features=VaapiVideoDecoder
–use-gl=desktop

in file ~/.config/chromium-flags.conf

Still not works.

[Yochanan]

Did you test with a video that’s at least 720p?

[nfm886]

Yes. Still no luck

[Yochanan]

Did you try this?

To reduce CPU usage while watching YouTube where VP8/VP9 hardware decoding is not available use the h264ify or enhanced-h264ify extension.

You can check what your GPU supports running vainfo (part of libva-utils).

[nfm886]

Just installed h264ify and it says FFmpegVideoDecoder. CPU usage is high even on 1080p
It definitely not works

Even under opera://flags “Hardware video decode” is not there.

[Yochanan]

@nfm886

installed h264ify

What did you choose to block? Your GPU supports h264 and VP9, so don’t block those.

@nfm886

under opera://flags “Hardware video decode” is not there.

Right, that flag has been replaced as I mentioned above.

[nfm886]

Ok, from what I see, it looks like Opera does not works with chromium-flags.conf
There is no flags switched in opera://flags, everything is default.

[nfm886]

Got it working in Vivaldi by changing settings manually

[Yochanan]

@nfm886

it looks like Opera does not works with chromium-flags.conf

Yes, it does. check chrome://gpu and look at Command Line, you should see the flags you enabled.

EDIT: Apparently something changed. Add the flags to /etc/opera/default instead:

OPERA_FLAGS="
--ignore-gpu-blocklist
--enable-gpu-rasterization
--enable-zero-copy
--enable-features=VaapiVideoDecoder
--use-gl=desktop
"

@nfm886

There is no flags switched in opera://flags

They’re two different things. Some options can only be added to the config file as command line flags.

[nfm886]

@Yochanan

you should see the flags you enabled.

I think they are not enabled

[Yochanan]

Yeah, just realized that. I edited my post above.

[nfm886]

Bingo!

[Yochanan]

Right-o. Time to update my guide.
