gst-launch-1.0 v4l2src ! tee name=t \
    t. ! queue ! videoscale ! video/x-raw,width=640,height=480 ! \
            videoconvert ! autovideosink
    t. ! queue ! videoscale ! video/x-raw,width=360,height=240 ! \
            videoconvert ! autovideosink -v


(if you're still on 0.10, replace videoconvert with ffmpegcolorspace and
gst-launch-1.0 with gst-launch-0.10).

The same should work with different inputs as well of course, and you
can add more t. ! queue ! ...  branches.
