I have this video playback issue with my Raspberry Pi 4b, 8GB of RAM. My operating system is UBUNTU Desktop, 64 bit version.

spinn2046@UbuntuDesktop:~$ uname -a
Linux UbuntuDesktop 5.11.0-1027-raspi #30-Ubuntu SMP PREEMPT Thu Jan 13 12:52:48 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux

My processor type, hardware platform and operating system are all aarch64 architecture.

I'm just a Linux beginner, so this is all I know:

spinn2046@UbuntuDesktop:~$ uname -sr
Linux 5.11.0-1027-raspi
spinn2046@UbuntuDesktop:~$ uname -v

The YouTube videos are choppy no matter the quality.

1080p the same as 480p or even 240p, they are very choppy, to the point I cannot normally watch them. They look like 4 fps.

Movies played using VLC (1920x1080) are the same - look like 4 fps.

I've found "stats for nerds" on YouTube and there is 1768 dropped out of 3566 frames, while playing 240p video. All 4 CPU cores usage is above 80% during YouTube playback of 240p video.

Sound is smooth and normal quality.

Even mouse pointer is annoyingly slow - to the point I need to wait 4 it. I want to use my Raspberry Pi 4b to watch theatrical movies on my TV or big 21:9 computer display and at the moment it's impossible.

EDIT:Something's really improved after I've upgraded to Ubuntu 21.10 and had Firefox updated to the newest version available on snapd.
