Gnome nautilus: howto enable the FLV preview

[Dario Lesca <d lesca solinos it>]

Hello! ... How To enable the FLV preview into Gnome Nautilus?

If I goto a folder witch contain .avi .mpg and .flv files, for .flv
files do not see the preview of video....

I have this pkg installed:

> $ yum --enablerepo livna list|grep -i -E '(totem|gstreamer)'|grep installed
> gstreamer.i386                           0.10.19-1.fc9          installed

What's missing?

Many thanks
