linux gnome online video play issue

Question

I'm using arch linux with gnome.

All the online video always show buffering but my network seems available(at least fast enough to browse stackoverflow).Actually when I get to a particular spot of the video,the frame can be shown successfully while it is still buffering.btw,youtube's video preview(mouse hovering) is ok,i can see that.

youtube screenshot It was fine before I turn my desktop environment form xfce4 to gnome.

here is my /var/log/pacman.log

but i don't think any of it involves the problem ps:only this part involves removal,others are things like pacman -Syu

I've checked the Internet and turned off all the gnome extension,I also reinstalled ffmpeg,but obviously it's kind like online video thing。
