The support for buffer exports in VA-API was added in version 0.36. These interfaces are for interop with EGL, OpenCL, etc. GStreamer-VAAPI uses it for a dmabuf memory allocator. Though, gstreamer-vaapi has to support VA-API versions ranging from 0.30.4, which doesn't support it. This patch guards all the buffer exports handling (and dmabuf allocator) if the detected VA-API version is below 0.36. https://bugzilla.gnome.org/show_bug.cgi?id=746405
