The automatically generated pipeline depends entirely on the media
itself and the set of plugins you have installed - playbin/decodebin
and friends are looking at the stream properties and searching for the
plugin with the highest rank which can be plugged there. The best place
to look at is usually the media graphs (.dot files) after playbin was
able to play something (I do this regularly, as my pipelines are
usually worse than the ones created by playbin).

Also the full-screen behavior depends the videosink configuration, so
hard to give universal answer, as none will fit all cases.
