Hardware-accelerated video encode?

[luetage]

@coronium I’m currently starting with vivaldi-snapshot --enable-features=VaapiVideoDecoder --use-gl=desktop and I enable the gpu rasterization flag additionally. And yeah, knowing for sure is more advanced. One easy thing you can do of course is checking cpu usage when running videos with and without flags.

I am just wondering how could I know for sure that Vivaldi is using hardware video acceleration?

Basically this way https://wiki.archlinux.org/title/Chromium#Tips_and_tricks, or checking it out by yourself by looking at your sensors/system monitor, like @luetage said

But I'm not even sure that Vivaldi is compiled with the certain flag enabled to support it, because from previous experimentations (of mine) with it, as far as I remember (Arch's) Chromium utilized it but Vivaldi not (nvidia on X11, no idea about Wayland) . /edit: Just checked my notes and V should utilize it as well. I'm not using it as I have enough CPU power and only a 1.7Mpixel monitor

@npro Thnx npro. I was fan of Opera (earlier time) and Vivaldi, but I am slowly moving toward to Firefox. By me opinion the Vivaldi doesn't work as expected on Linux.
I was struggling for a while to make it work smoothly. A huge obstacle for me is a "stuttering" and slow mouse-wheel scrolling. Firefox does it better. All functionality of Vivaldi can be added to Firefox by add-ons (for example: automaticDark, Add custom search engine, Offline QR Code Generator, Simple Context Search, Translate Web Pages, uBlock Origin, Undo Close Tab, Translate Web Pages, etc..).

I really appreciate a huge effort and hard work of Vivaldi team, however I think the problem is in a chromium project (at least for Linux devices).

Firefox runs everything smoothly, for example adding to prefs.js (or in about:config preferences),

user_pref("app.normandy.enabled", false);
user_pref("app.shield.optoutstudies.enabled", false);

user_pref("browser.aboutConfig.showWarning", false);
user_pref("browser.compactmode.show", true);
user_pref("browser.link.open_newwindow.restriction", 0);
user_pref("browser.newtabpage.activity-stream.showSearch", false);

user_pref("widget.non-native-theme.scrollbar.size", 12);

user_pref("services.sync.prefs.dangerously_allow_arbitrary", true);

as well as h264ify add-on.

Moreover, I can recreate "speed dial" (so called pinned sites) by modifying the userContent.css file in chrome profile folder, for example as:

@-moz-document url(chrome://browser/content/browser.xul), url(about:newtab), url(about:home) {

	main {

        --trailhead-header-text-color: #D4DEA9 !important;
		}
    }

At the end, the Firefox works better on Linux machines and I have more power to adjust it by my needs.

Thanks again for an effort for a help, I appreciate it very much.

Greetings, C.

@npro I found out that on intel cards it is better to check with:

sudo intel_gpu_top 

or radeon cards with:

sudo radeontop

Therefore, on "Video line/row" should be the percentage of GPU decoding...

I hope it will help someone...
Tnx, cheers...
