thanks for the info. so it seems chromium need to co-work with VLC when there is 4k video.I wouldn't expect this to work. VLC can only do 4k video on the Pi 4 by using a carefully optimised pathway which avoids putting video frames through the GPU. Chromium's rendering will all go through the GPU so it won't be able to keep up with 4k on Pi4.
Even on a Pi5 1080p60 video playback in chromium/firefox works the GPU very hard.
