Will be easier to maintain and to make enhancements. Tested with Tizonia on Desktop. Also tested with Bellagio to make sure it does not crash when calling OMX_UseEGLImage and indeed it returns NotImplemented. Then gst-omx fallback to OMX_UseBuffer if it can and so on. Also tested on rpi to make sure there is no regression. https://bugzilla.gnome.org/show_bug.cgi?id=784365
