WebMParser: set duration and dts correctly
- dts was not set earlier, although for WebM, we could assume that dts is the same as pts. - Calculate block duration with the difference with the next block if duration is not encoded, even if track default_duration is set. - Use track default_duration as a duration estimate for the last block. - This also removes opus duration computation from encoded data. Issues #67, #68 Change-Id: Icaa2769dcb2a89269ae014f44ad6a9262770aed2
