Hi everybody, I have the beta version of Opera cause I had a bug in the stable version, the bad thing is that in the beta version I can't see videos on Drive, Facebook, Instagram, etc. I know that it is due to the Chromium Codecs. I already searched for the Codec that serve in the version of my browser but I couldn't find it, somebody have these lib or know where to find it?

My S.O. : Debian10.

thanks and excuse me my bad english
