Experimental Features
---------------------
I observe high CPU usage during video playback about 30-40%
When I use Kodi for 1080p h264, HEVC content I have about 5-8%.
Can I turn on hardware video acceleration in PaleMonn or currently this is not supported?
If not when VAAPI support could be added?
My system:

What does the Graphics section look like when you go to about:support (Sort of like about:config). I've attached a screen-capture of mine, on a 2008 Intel Core2, running Gentoo. Is GPU Accelerated Windows enabled?

My Graphics section is as follows:

Unfortunately I have:

How to switch it on?

GPU Accelerated Windows: 0/1 Basic looks like the problem. I had to set it up manually on my system. Try the following expeiment. It assumes you use bash as your default shell
  • * copy this post to a text file
    * open a terminal (xterm or whatever)
    * in the terminal execute killall palemoon (that's why you need a separate copy of this post)
    * in the terminal execute export MOZ_USE_OMTC=1
    * in the terminal execute palemoon
    * in Pale Moon go to about:support and check "Graphics" again
If you get "1/1" instead of "0/1" it worked. If not, don't bother with the following.
  • * Test it on some videos that spike the cpu, to see if it helps.
    * The next step is to implement this permanently.
    * edit/insert the command export MOZ_USE_OMTC=1 into .bashrc and .bash_profile
    * shut down X and restart X
Pale Moon should start up with acceleration enabled when launched.

I use LXDE shell (lubuntu-core installed in ubuntu server 17.10)
After

Code: Select all

export MOZ_USE_OMTC=1
from terminal I still see:

Code: Select all

GPU Accelerated Windows: 0/1 Basic
but now I see 'palemoon' as a running process

Code: Select all

/usr/sbin/lightdm
	lightdm--session-child 13 16
		/usr/bin/lxsession -s LXDE -e LXDE
			lxpanel --profile LXDE
				palemoon
Before was 'x-www-browser' or something like this

Sorry, it looks like that doesn't work. I can't think of anything else. I have the same problem on my old ASUS Atom netbook.

That's not important. It's a function of being launched manually from the commandline, versus via the launchbar.

Thank you.
It's working now :)
I set additionally (in about:config):

Code: Select all

webgl.force-enabled = true.
layers.acceleration.force-enabled = true
layers.offmainthreadcomposition.enabled  = true
Now I see:

Code: Select all

Adapter Description: Intel Open Source Technology Center -- Mesa DRI Intel(R) HD Graphics 500 (Broxton 2x6)
Device ID: Mesa DRI Intel(R) HD Graphics 500 (Broxton 2x6)
Driver Version: 3.0 Mesa 17.2.2
GPU Accelerated Windows: 1/1 OpenGL (OMTC)
Vendor ID: Intel Open Source Technology Center
WebGL Renderer: Intel Open Source Technology Center -- Mesa DRI Intel(R) HD Graphics 500 (Broxton 2x6)
windowLayerManagerRemote: true
AzureCanvasBackend: cairo
AzureContentBackend: cairo
AzureFallbackCanvasBackend: none
AzureSkiaAccelerated: 0
However the improvement is not spectacular. ;)
From 30-40% CPU usage to about 20%.
When I use Kodi for HD H.264 or HVEC content I have ~6%

I do not comment about the numbers you are seeing, but one thing to keep in mind is that a dedicated video player will always use less CPU than a web browser for the same video content. This is due to the complexity in the browser, and player being optimized for video.
