Chrome browser - video hardware acceleration (vdpau / va-api)

I have a old laptop with a NVIDIA GeForce G103M that I'm using for kodi. Using the Generic-legacy image, video playback is running smooth with low CPU usage.

With chrome the dual core CPU has a high CPU usage for video playback and according to chrome://gpu the video decode is done by software.

Does libva-vdpau-driver work with nvidia legacy driver? Will this work with chrome to enable va-api video decoding?

regards

I tested installing vainfo executables, from arch package libva-utils to "~/.kodi/addons/browser.chrome/bin" and arch package libva-vdpau-driver to "~/.kodi/addons/browser.chrome/lib/dri" but that did not work to activate the vdpau->libva translation layer.

The output of vainfo:

# vainfo  
Trying display: x11

libva info: VA-API version 1.17.0
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
vaInitialize failed with error code -1 (unknown libva error),exit

Perhaps the libva-vdpau-driver files need to be installed to "/usr/lib/dri/"

To force va-api vdpau and nvidia proprietary drivers we can use the environment variables:

VDPAU_DRIVER=nvidia

LIBVA_DRIVER_NAME=vdpau
