PureBrowser Hardware Acceleration Unsupported?


#1

If Hardware Acceleration is not supported by PureBrowser,
it should be disclosed to future purchasers before they buy.
Because this means you can’t watch a video and search the web at the same time,
like most people do, without experiencing sluggishness.

Everything freezes for seconds when you accidentally start a 2nd video.
This happens a lot while queuing up the next video in a new tab,

In Purebrowser, about:config, enable layers.acceleration.force-enabled
and it still requires 100% cpu to watch youtube videos.

I tried https://addons.mozilla.org/en-US/firefox/addon/h264ify/

I tried chromium. It won’t accelerate videos either.

If there is a solution to this, why is it not the default setting?

I very disappointed I can’t recommend this really nice 4k 15" laptop as a media consumption device.

Can someone please tell me what I’m doing wrong?

Hardware Video Acceleration is still touch and go on Linux in general (especially on ARM). Things have gotten a lot better with dedicated video applications but browsers are a whole 'nother ball of wax. Neither Firefox nor Chromium support it in Linux. The latter even has a special build in some distros to enable it. Check out this entry in the Arch Wiki about Application Support.

To help with this issue, Mladen wrote this PureOS Wiki entry to allow web videos to be opened in GNOME MPV from PureBrowser. its a lot less resource intensive doing so through MPV than a browser, even at 720p+.

this should work better in VLC no ? as far as i know MPV is installed together with youtube-dl.
