If it’s just a customized version of labwc‘ YouTube playback is still slow with Firefox‘，So it’s possible。
Labwc customized version (supports 1080p streaming hardware decoding)，Only VPU driver, no GPU driver, So hardware decoding of streaming media is possible, but video output requires a CPU, and when the CPU is busy, video playback may be slow.
So when the playback speed is slow, try lowering the monitor resolution to see if it can improve playback speed。
wlr-randr --output HDMI-A-1 --mode 1920x1080
wlr-randr --output HDMI-A-1 --mode 1366x768
Finally, a reminder that the key to hardware decoding for this version of streaming media is to use Firefox119.
This system has been fully upgraded with apt, except for Firefox119.
It can also be fully upgraded with apt in the future, except for Firefox119.
