  Success.  After a bit of experimenting I've gotten h.264 working at
the quirksmode website, and on Youtube.  Pale Moon browser requires...

gstreamer
gst-plugins-base
gst-plugins-good
gst-plugins-ffmpeg

  A confusing item is that gst-plugins-base and gst-plugins-good are in
media-libs/ but gst-plugins-ffmpeg and 77 others are in media-plugins/
Go figure.

  Nothing on my system requires 1.X and I prefer a lean system.

There is no need to remove the 1.x version of gstreamer (unless you
just don't need it anymore).  The 0.8, 0.10, and 1.x branches of
gstreamer are each slotted (well, the ancient 0.8 release is gone from
the tree as nothing uses it any more) specifically so that they can be
installed in parallel, and upstream actually supports doing so (which
is why the ABI version number is in the name of every library, plugin
directory, and executable).
