I bought Poweramp and Poweramp eq.Think you for your wonderful software.
I hope to be able to use eq on bilibili or other video players.
Thanks.

Wait a minute,I just found bilibili in player list,emememm. I uninstalld Poweramp eq and reinstalled, and bilibili also not in any list.
About three days later, I found bilibili in player list,not in advanced list.
It works now.
