+xbmc (2:12.0~git20121117.0151446-1) experimental; urgency=low
+
+  * For XBMC Frodo (v12.0), XBMC will be built and run using XBMC's internal
+    fork of FFMpeg. The specific branch that the fork is forked from is
+    FFMpeg's 10.2 branch.
+    .
+    The decision was made to use the internal copy of FFMpeg because a
+    large amount of work would be required in order to get XBMC building
+    and running with both FFMpeg and Libav. In the case of Debian and it's
+    derivatives, there would have been no benefit in getting XBMC at least
+    working with FFMpeg installed as system libraries, since Debian
+    currently only has Libav.
