Subject: dashdemux: Use the smallest queue value to define buffering state
X-Git-Tag: 1.19.3~507^2~13579
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3a055ac2d10b055749c3aff6ee5555e9538ec69d;p=platform%2Fupstream%2Fgstreamer.git

dashdemux: Use the smallest queue value to define buffering state

The smallest queue should be used to prevent blocking the download
thread when a stream has too much data buffered, leaving the other
streams starving from fragments
