Hi all,

I am not sure if this is even my main issue but, checking the chrome://gpu and brave://gpu in both, chrome or brave browsers, I am not getting any other information under Video Acceleration Information except empty lines for decoding and encoding:

I am using the official nvidia drivers

The Proton games, for example, work without issues, here is also a “stats for nerds” info from a 4k video on youtube:

I’ve tried most of the suggestions from other topics, installing ffmpeg is installed, I’ve ran chrome or brave with flags such as

flatpak run com.brave.Browser --use-gl=desktop \
--enable-accelerated-video-decode \
--enable-accelerated-video-encode \
--enable-features=VaapiVideoDecoder \
--disable-features=UseChromeOSDirectVideoDecoder \
--ignore-gpu-blocklist \
--enable-zero-copy

Still, I can’t seem to bring anything else to the brave://gpu table.

What am I doing wrong?

Try

google-chrome --enable-features=AcceleratedVideoDecodeLinuxGL,AcceleratedVideoEncoder

Thank you for your feedback @leigh123linux .

I’ve updated the flag, now both Video Decode and Video Encode show as green, still, my Video Acceleration Information is completely empty -

as I’ve understood, the VAI should be populated and should look like this:
