From Julen Garcia, "Here there is a small plugin I use to play video files. It is based on GStreamer http://gstreamer.freedesktop.org and I have used the FFmpeg plugin as inspiration."
From Robert Osfield, fixed handled of row widths so that they are padded to a 4 byte boundary as certain row widths were being rendered incorrectly. git-svn-id: http://svn.openscenegraph.org/osg/OpenSceneGraph/trunk@14604 16af8721-9629-0410-8352-f15c8da7e697
