Chromium: Can't enable Video encoding: Hardware acceleration

Support Software & Applications
1

amd rx 550 and brave Version 1.34.81 Chromium: 97.0.4692.99 (Official Build) unknown (64-bit)

i cant enable Video encoding: Hardware acceleration

if i do using flag --enable-features=VaapiVideoEncoder it disables accelerated video decoding

any ideas?

@Omh Everyone has their own set of flags so here’s mine:

.config/chromium-flags.conf

--force-dark-mode
--enable-features=WebUIDarkMode
--enable-features=VaapiVideoEncoder,VaapiVideoDecoder,CanvasOopRasterization
--enable-zero-copy
--use-gl=desktop
--ignore-gpu-blocklist
--enable-oop-rasterization
--enable-raw-draw
--enable-gpu-rasterization
--use-vulkan
--disable-reading-from-canvas
--disable-sync-preferences

Hardware acceleration for video encoding is not available in Linux, as far as I know.
Unfortunately, when searching for more information on that topic, Artificial Intelligences strikes and modifies your search, replacing encode by decode :frowning:

Here’s what chrome://gpu usually says in the Linux versions of chromium:

However, @ishaan2479 apparently has a solution:

Found something for brave:

Can you confirm if it’s working on chromium or not? Verify the settings for VA-API by running vainfo. Also install vdpauinfo to verify if the VDPAU driver is loaded correctly. More info.

I use Brave

so i used these flags to brave launcher

--use-gl=desktop --enable-features=VaapiVideoDecoder --disable-gpu-driver-bug-workarounds --enable-features=VaapiVideoEncoder,VaapiVideoDecoder,CanvasOopRasterization

on brave://flags/

enabled these

#ignore-gpu-blocklist

#enable-gpu-rasterization

#enable-zero-copy

#enable-vulkan

#canvas-oop-rasterization

and brave://gpu/ reports

Looks like it is not only the Artificial Intelligence but the natural one as well that is not able to cope with encoding vs. decoding :smiley:
