[Vignesh Venkatasubramanian]

ffmpeg | branch: master | Vignesh Venkatasubramanian <vigneshv at google.com> | Tue Apr 21 16:36:52 2015 -0700| [4f287a3c5007db853e4f1098ab194f9337e2f7da] | committer: Michael Niedermayer

webmdashenc: Add minimumUpdatePeriod

DASH spec requires the presence of either duration of the period
or the minimumUpdatePeriod element. This patch adds the
minimumUpdatePeriod element hardcoded with the value 0 as the
manifest will never be updated for WebM DASH Live streams. Also
updating the fate test reference file.
