14 # @BLURB: Helps building core & split gstreamer plugins.
15 # @DESCRIPTION:
16 # Eclass to make external gst-plugins emergable on a per-plugin basis
17 # and to solve the problem with gst-plugins generating far too much
18 # unneeded dependencies.
19 #
20 # GStreamer consuming applications should depend on the specific plugins
21 # they need as defined in their source code. Usually you can find that
22 # out by grepping the source tree for 'factory_make'. If it uses playbin
23 # plugin, consider adding media-plugins/gst-plugins-meta dependency, but
24 # also list any packages that provide explicitly requested plugins.
