Subject: wavparse: ensure that any pending segment is sent before an EOS event is sent
X-Git-Tag: 1.22.0~1679
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f4f342aa7827834d486c7320be28c878eb27c4b0;p=platform%2Fupstream%2Fgstreamer.git

wavparse: ensure that any pending segment is sent before an EOS event is sent

Specifically fixes seqnum handling when an aggregator-based element
(audiomixer et al) is downstream and a seek is performed that
immediately causes an EOS from wavparse.
