Description Mikhail N 2018-01-13 02:29:23 MSK
Rosa previously had a patch which enabled chrome://flags#enable-accelerated-video (off by default) hich ported VA-API accelerated video playback from Chrome OS.
Currently on my system this patch + h264ify chromium extension + 'block 60 fps' option ON in h264ify = helps me to unload the CPU and playback Youtube videos smoothly, otherwise the CPU is loaded for 100% and the playback is not smooth
I am using Ubuntu 17.10 + patched Chromium from https://launchpad.net/~saiarcot895/+archive/ubuntu/chromium-dev , 
the patch : https://github.com/saiarcot895/chromium-ubuntu-build/commit/f8bd4a884894c47f7bce04c7b4d25a714c7a2faa , it worked at the time of Chromium 63 and continues to work now in 65

ALT Linux also has this patch in the default chromium build, but is seemd to be a bit different from this one, and VA-API did not work in ALT Linux on my system, however, I have not investigated deeply. https://packages.altlinux.org/ru/Sisyphus/srpms/chromium/patches/0022-Enable-VAVDA-VAVEA-and-VAJDA-on-linux-with-VAAPI-only.patch 

Note that this is the source of the working VA-API patch https://github.com/saiarcot895/chromium-ubuntu-build/blob/master/debian/patches/enable_vaapi_on_linux_2.diff , but it is currently for Chromium 65, you can find an older version for older Chromiums in the Git history.
