Subject: [PATCH] Enable accelerated video decode on Linux
|
||||
|
||||
This will enable accelerated video decode on Linux by default (i.e.
|
||||
without "--ignore-gpu-blacklist"), but on NixOS we'll provide
|
||||
"--disable-accelerated-video-decode" and
|
||||
"--disable-accelerated-video-encode" by default to avoid regressions
|
||||
(e.g. VA-API doesn't work properly for some radeon drivers).
|
||||
|
||||
Video acceleration can then be enabled via:
|
||||
chromium.override { enableVaapi = true; }
|
||||
without rebuilding Chromium.
