You'll want *-base (say, 0.10.30), *-good (=> 0.10.23) and *-bad (=>
0.10.19), and also libvpx. Newer is better. You may also need
shared-mime-info => 0.71-2, or equivalent MIME-type updates for your
system. [1]
If you happen to be running Ubuntu, these are satisfied by the
packages shipping with 10.10 (Maverick).
Can't speak for Matlab video renderer specifically, though.
