Subject: qmlglsink: Expose itemInitialized as property
X-Git-Tag: 1.19.3~509^2~1695^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a0d526a2a85f350576884c70cf40477fd0c2afd7;p=platform%2Fupstream%2Fgstreamer.git

qmlglsink: Expose itemInitialized as property

Instead of just signalling when ready exposing the state
as a property allows us to bind at any time if player is
loaded async.
