Putting a video inside another video

Yeah i got it working now, i forgot to use decodebin. 

Final pipeline : 

gst-launch-1.0 -ve videomixer name=mixer sink_1::alpha=0.5 sink_1::xpos=50
sink_1::ypos=50 ! videoconvert ! autovideosink sync=true \
          filesrc location=FILE1 ! decodebin name=db ! queue2 ! mixer. \
          filesrc location=FILE2 ! decodebin ! queue2 ! mixer. \
          db. ! audioconvert ! pulsesink

This also plays first videos sound. Any advice about improvements? How
should i encode the raw videos coming out from decodebin for more smoothness
and/or performance?
