Subject: event: add SELECT and UNSELECT stream flags for stream-start event
X-Git-Tag: 1.1.1~188
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=caa06788c31e5c229e7733757f9d7fd583330bac;p=platform%2Fupstream%2Fgstreamer.git

event: add SELECT and UNSELECT stream flags for stream-start event

So demuxers can signal which audio/video/subtitle streams should
be selected by default and which should not be selected
automatically.

API: GST_STREAM_FLAG_SELECT
API: GST_STREAM_FLAG_UNSELECT
