@xzero that does not work to me,
have to check few more codecs from here - http://security.ubuntu.com/ubuntu/pool/universe/c/chromium-browser/?C=M;O=A
currently working only with the codec from "chromium-codecs-ffmpeg-extra_94.0.4606.81-0ubuntu0.18.04.1_amd64.deb"
My PC is:
Linux Mint 20.2 Cinnamon / kernel 5.4.0-89-generic
i386 codecs does not work to me.
