That's because mp4mux needs to write headers and tables after all the
data has been processed. If you just control-C, the file will be closed
without mp4mux having an opportunity to finalise everything.

Pass -e to gst-launch-1.0, then it should finalise everything also on
Control-C. (If you write an application, do
gst_element_send_event(pipeline,gst_event_new_eos()) and then wait for
the EOS message on the bus before setting the pipeline to NULL state).
