Have a look at the gst-launch-ext script in gst-plugins in CVS. It uses
this:

gst-launch filesrc location="test.avi" ! decodebin name=d { d. ! queue !
ffmpegcolorspace ! xvimagesink } { d. ! queue ! audioconvert !
audioscale ! osssink }

You can later on decide to s/decodebin/elements/, e.g. for a DIVX4/5
file:

gst-launch filesrc location="test.avi" ! avidemux name=d { d.video_00 !
queue ! ffdec_mpeg4 ! ffmpegcolorspace ! xvimagesink } { d.audio_00 !
mad ! audioconvert ! audioscale ! osssink }

HTH,

Ronald
