Check out the "playbin" element:

  gst-launch-1.0 playbin uri=<your_media>

Mind that "uri" is different from "location", for instance you'll need
to prepend "file://" to the path of local files.

You can configure many of playbin properties with gst-launch-1.0, see
"gst-inspect-1.0 playbin".

The playbin element does all that internally.

Check also gst-play-1.0 for a quick way to use GStreamer from
the command line.
