+Have you noticed gstreamer0.10-decoders and gstreamer0.10-decoders-audio ? 
+Those can do the same as your point 2. but for all plugins independent of 
+the source packages. So basically task- packages for gstreamer plugins 
+that totem, other players and transcoders/editors can use.
+
+That way you get meta packages for demuxers, muxers, audio-decoders, 
+audio-encoders, video-decoders, and video-encoders which depend on the 
+standard/typical plugins.
