+Subject: [PATCH 4/4] subparse: set need_segment after sink pad received
+ GST_EVENT_SEGMENT
+
+subparse works in push mode, chain funciton will be called once
+up stream element finished the seeking and flushing.
+if set need_segment flag in src pad event handler, the segment
+event will be pushed earlier, result in the subtitle text will
+be send out to down stream from the beginning.
+
+Upstream-Status: Inappropriate [i.MX specific]
