+GStreamer uses a *large* array of tools and libraries, most of which are
+optional. We have attempted to make sure that any code that depends on
+optional libraries doesn't get built unless you have those libraries. If
+you find this not to be the case, please, let us know by filing a bug
+report at http://bugzilla.gnome.org/.
-a52dec 0.7.3
-avifile >= 0.6.0 (cvs)
+On Debian/Ubuntu, the easiest way to install most build requirements is:
+ sudo apt-get build-dep gst-plugins-good1.0
+
+Required tools:
+===============
+
+An extra set of tools is required if you wish to build GStreamer
+from git (using autogen.sh):
+
+autoconf >= 2.68 https://www.gnu.org/software/autoconf/
+automake >= 1.11 https://www.gnu.org/software/automake/
+gettext >= 0.17 https://www.gnu.org/software/gettext/
+libtool >= 2.2.6 https://www.gnu.org/software/libtool/
+pkgconfig >= 0.9.0 https://www.freedesktop.org/software/pkgconfig/
+
+Required libraries:
+===================
+
+Package: GStreamer
+Version: 1.x (same 1.x version as this package)
+Recommended: Latest 1.x
+URL: http://gstreamer.freedesktop.org/
+DebianPackage: libgstreamer1.0-dev
+Notes: The required version is updated frequently, so the version
+ listed in this file is often out of date. If you are compiling
+ from git master, you will usually need GStreamer core and
+ gst-plugins-base from git master as well.
+
+Package: GStreamer Base Plugins
+Version: 1.x (same 1.x version as this package)
+Recommended: Latest 1.x
+URL: http://gstreamer.freedesktop.org/
