audio/video packages for ubuntu

[JD]

Wouldlike to install several audio/video libraries,
that provide flac, vorbis, wma, wmv, mpX....etc

except I do not know the exact package names.

How does one query the ubuntu repos using wildcards
as is done with yum on redhat distros:
yum list available "*flac*"

andit lists every available package containing the word flaci
in the "enabled" repos in /etc/yum.repos.d/

Thanx.
