google chrome – Website with video use much CPU after hours

I have a webpage (VueJS) that show videos like this https://imgur.com/LLNq8qW

I run it in server aws (8 vcpu, xvfb+chrome), it was fine at the beginning. But after 1-2 hours. The server ran out of CPU. The chrome process take 300-400% CPU ( RAM still fine ). I tried to debug with chrome developer tools but still have no clue.
