v4l2src is part of gst-plugins-good.

Make sure it exists with


 gst-inspect-{0.10|1.0} v4l2src

Make sure it did not get blacklisted for some reason with:

 gst-inspect-{0.10|1.0} -b

Make sure you have the right binary, by looking for a file called
libgstvideo4linux.so usually somewhere in /usr/lib/gstreamer-{0.10|
1.0}/plugins/
