4Subject: [PATCH 4/6] [glplugin] enable gldeinterlace on OpenGL ES
5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
91.Porting the exist deinterlace shader and OpenGL callback
10 to be compatible with OpenGL ES.
112.Add a our blur vertical shader to gldeinterlace.
123.Add a property named “method” to let user choose which
13 deinterlace function to use. Default to choose blur vertical
14 method for better performance.
15
16Upstream-Status: Backport [1.9.1]
