Help with syntax

[Rick T]

Greetings All

I'm having trouble getting the following line to work
I get an error "WARNING: erroneous pipeline: link without source element"

I think I narrowed it down to the audio section but I'm not sure how
to fix it can some one assist?

Thanks  See code below

gst-launch-0.10 v4l2src !
'video/x-raw-yuv,width=640,height=480,framerate=25/1' ! \
timeoverlay halignment=right valignment=bottom shaded-background=true ! \
clockoverlay halignment=left valignment=bottom text="M/D/Y:"
shaded-background=true time-format="%m/%d/%Y %H:%M:%S" ! \
tee name=t_vid ! queue ! xvimagesink sync=false t_vid. ! queue ! videorate ! \
'video/x-raw-yuv,framerate=25/1' ! xvidenc ! queue ! mux. ! \
audioconvert ! 'audio/x-raw-int,rate=44100,channels=2' \
