I am having an issue watching hd (720 or 1080) videos on Ubuntu 21.04 fresh install. I get really high cpu usage (50% on all cores) which is pretty high for a 720p vid. I tried watching the same video on vlc (hw acceleration) and it works perfectly fine. I even tried a 4k video and it works fine cpu usage < 20%. Why is chrome consuming so much cpu?
flags enabled:
Here is what I have tried: sudo apt install intel-media-va-driver
CPU usage on vlc with 4k video h265, vlc is on second line, gnome for some reason takes a HUGE screenshot (6MB, had to compress):

EDIT:
Okay, this may be something more deep than I originally thought. Ubuntu has performance settings powersave, balanced, and performance. Setting it to performance works great and everything seems normal. But checking the governer:
sudo apt-get install cpufrequtils
Check the governer cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor powersave powersave powersave powersave powersave powersave powersave powersave
I set the governer to performance and now it looks to be working much better:
sudo nano /etc/default/cpufrequtils
and setting:
GOVERNOR="performance"
Then restarting the service
sudo systemctl restart cpufrequtils
EDIT 2:
Following along with what Michal Przybylowicz said, it looks like the decoder is not a hardware decoder? What is going on here? Why isnt chome or ubuntu using the hardware decoder?
EDIT 2.5: Here is the output of vainfo:

and whats up with this issue:

I also saw this when loading retroarch, I tried launching chrome after setting sysctl dev.i915.perf_stream_paranoid=0 and it made no change, still sw decoder.
It looks like others have been having the same issue: https://www.reddit.com/r/chrome/comments/n6qywt/hardware_acceleration_fail_in_chrome_on_linux/
