-Yes, we have no X dependency in any of our core modules. There are GStreamer
-applications that run fine without any need for X.  However, until our Linux

+Yes, we have no hard X dependency in any of our modules. There are many
+GStreamer applications that run fine without any need for X, for example
+streaming servers, transcoding applications, or audio applications that
+don't output any video. Other applications output video to a framebuffer,

-No. But many of the applications developed for GStreamer do, including our
