I'm hoping that playbin will build a decent decode pipeline and I can then use the frames in fakesink to create an OpenGLES texture which I can render in my app. This also gives a portable way of rendering the video where I want, at the size I need and without and decoration. I was hoping that glupload may help make this more efficient, but I can't even get gst-plugins-gl to build at the moment.
