Actually, the application bases on a SIP protocol to Play/Playbak streaming
with sip INVITE.

And the pipeline as following:
recordingbin ! mpegpsmux ! rtpmp2pspay ! udpsink

And the recordingbin is responsible for SEEK handing, I succeed in
fast-forward with SEEK, but just like what I have talked above.
