The purpose of gstcompat.h is to couple the API differences among gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code in this compatibility layer shall be removed. Nevertheless, the gstcompat.h header should be kept, if new incompatibilites appear in the future, but it shall live in gst/vaapi, not in gst-libs. This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi. In order to avoid layer violations, gstcompat.h includes sysdeps.h and all the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h https://bugzilla.gnome.org/show_bug.cgi?id=745728 Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com> Signed-off-by: Sreerenj Balachandran <sreerenj.balachandran@intel.com>
