I'm not sure why you wanted to do this manually, but anyway. Here's a
pipeline that fits the media you have chosen. I have no idea about
fluvmcdec, so I have used avdec_wmv3, you may try and replace it.

gst-launch-1.0  \
  filesrc location=Amazon_1080.wmv ! asfdemux name=demux \
  demux. ! queue ! avdec_wmv3 ! theoraenc ! mux. \
  demux. ! queue ! avdec_wmapro ! vorbisenc ! mux. \
  oggmux name=mux ! filesink location=test.ogg

Obviously you will have to rewrite this pipeline for each media. A more
generic pipeline would be:

gst-launch-1.0  \
  filesrc location=Amazon_1080.wmv ! decodebin name=dec \
  dec. ! video/x-raw ! queue ! theoraenc ! mux. \
  dec. ! audio/x-raw ! queue ! vorbisenc ! mux. \
  oggmux name=mux ! filesink location=test.ogg

If fluwmvdec is a fit for the task and is ranked high enough, decodebin
bin will pick it automatically. All you have to care is to make sure it
is installed.
