Bad Jitsi browser performance on Raspberry Pi 4B

Hi

I have a Jitsi server running on a strong dedicated Ubuntu server. People can join my meetings and have good performance. When I open the same meeting with chromium on my Raspberry Pi 4B 2GB RAM, my fps dips to about 3-5 fps with often couple seconds long freezes. My connection quality is all over the place although I have very good Wi-Fi and LAN doesn’t improve anything. But even when my connection quality is green or “good”, my fps is very low.
I have a cooler running that keeps the Raspberry pi below 45*C.
I have the NOOBS software installed, could this be a cause?

Anyone knows what the problem is here?

Thanks

You need to enable the hardware H264 decoder for chromium
