Subject: Enable VA-API on desktop Linux by default
|
|
|
|
|
|
|
|
|
|
* enable VaapiVideoDecoderLinuxGL (equivalent of --enable-features=VaapiVideoDecoderLinuxGL)
|
|
|
|
|
which is needed to make VA-API work on desktop Linux
|
|
|
|
|
* track that VaapiVideoDecoder does not get disabled on updates
|
|
|
|
|
* enable HW decoding in WebRTC where possible

Equivalent for Google Chrome without this patch:
|
|
|
|
|
$ google-chrome --enable-features=VaapiVideoDecoder,VaapiVideoDecodeLinuxGL
|
|
|
|
|
(without HW decoding in WebRTC)

VA-API is also enabled out of the box in Ubuntu's Chromium snap in the hwacc-beta channel:

|
See build/chromium-patches/optimization/topic-intel
|
|
|
|
|
|
|
|
|
|
As a result, this patch makes VA-API work out of the box on Intel GPUs.
|
|
|
|
|
Tests showed that it does not work on AMD and Nvidia (with vaapi-driver-vdpau).
