It only outputs this for plugins that are built conditionally, which
are the plugins in the sys/ and ext/ directories. Plugins that are
built no matter what (like sinesrc) are listed.

I'm leaving this bug open as this is somehow confusing anmd the output
of configure should better reflect what is done there (and maybe
include hints on what to do to get plugins to built that are not built
currently).

Something related I'd like to see:

A configure flag like '--enable-all-plugins' that turned everything on (or at
least the useful plugins one would need for the bulk of the media on the
Internet)? I was looking for something like this so I could test out some of my
videos on totem-gstreamer CVS and report bugs against it. As it is the
'configure --help' output of gst-plugins is pretty daunting.

For that, I'd suggest to read the 'REQUIREMENTS' file for all optional packages,
or just install the RPMs. The RPMs for gst-plugins/-ffmpeg contain all useful
plugins, at least the ones provided by us (RedHat removes some for licensing
reasons).

--enable-all-plugins not likely to get added without a patch. Even with a patch
its semantics would be a bit dodgy -- best to check the configure output
instead. More of a job for a distro.

Agreed about the gst/ plugins. Added a patch to plugins-base to show gst/
plugins, should be added to other plugin modules shortly.
