Subject: baseparse: use _set_duration to configure duration update interval
X-Git-Tag: RELEASE-0.10.33~148
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=668ad3836ac0c9a1c4771b260422b3aaff54ce22;p=platform%2Fupstream%2Fgstreamer.git

baseparse: use _set_duration to configure duration update interval

... as it logically belongs there as one or the other; either subclass
can provide a duration, or an estimate must be made (reguarly updated).
