You have to set the multipass-cache-file property to some filename,
which is used to store the statistics of the first pass and then use
that same filename for the second pass.

E.g.

gst-launch-0.10 videotestsrc num-buffers=1000 ! theoraenc
multipass-cache-file=/tmp/bla multipass-mode=first-pass ! oggmux !
filesink location=test.ogg

gst-launch-0.10 videotestsrc num-buffers=1000 ! theoraenc
multipass-cache-file=/tmp/bla multipass-mode=second-pass ! oggmux !
filesink location=test.ogg
