Just one note. You can use this more simple pipeline:
*gst-launch-1.0 uridecodebin
uri=https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm
<https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm>
! x264enc ! mp4mux ! filesink location=sintel_trailer.mp4*
