--- Comment #2 from Thiago Sousa Santos <thiagossantos at gmail.com> ---
>From the spec (5.3.2.1):

"For any regular Period the following holds: PeriodStart reflects the actual
time that should elapse after playing the media of all prior Periods in this
media Presentation relative to the PeriodStart time of the first Period in the
Media Presentation. The Period extends until the PeriodStart of the next
Period, or until the end of the Media Presentation in the case of the last
Period. More specifically, the difference between the PeriodStart time of a
Period and either the PeriodStart time of the following Period, if this is not
the last Period, or the value of the MPD at mediaPresentationDuration if this is
the last one, is the presentation duration in Media Presentation time of the
media content represented by the Representations in this Period."

It seems that the media inside a period has to be limited by the next period's
start or the total mpd duration. So IMHO we should restrict the
duration/segments to the period's length.
