+Subject: [PATCH 4/6] [glplugin] enable gldeinterlace on OpenGL ES
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+1.Porting the exist deinterlace shader and OpenGL callback
+  to be compatible with OpenGL ES.
+2.Add a our blur vertical shader to gldeinterlace.
+3.Add a property named “method” to let user choose which
+  deinterlace function to use. Default to choose blur vertical
+  method for better performance.
+
+Upstream-Status: Backport [1.9.1]
