+Subject: [PATCH] vaapsink: downgrade to marginal
+
+Using vaapisink with default poky configuration results in an
+unresponsive display as of today because DRI2 rendering is currently broken
+in non composited environments [1] and libva doesn't support DRI3 [2].
+
+Downgrade vaapisink to marginal for now so playbin (and in turn gst-play
+and gtk-play examples) use xvimagesink or others out of box.
