+Summary: build ffmpeg libs as shared libs
+
+From Bug#104208:
+
+"I was thinking this is a problem of ffmpeg libs not being built
+shared.  Right now the ffmpeg plugin links to ibavcodec.a and
+libavformat.a.  I think the theory is that we have to change the build
+so that ffmpeg's configure script is called with --enable-shared.  I
+did this and can provide the patch but I'm not sure it matters. 
+ffmpeg only builds libavcodec.so not libavformat.so.  Just fixing one
+of the libs probably isn't enough.  Plus if you look at the ffmpeg
+build scripts it's not like it even bothers to use the flag to do
+-fPIC.  This is ok on x86 but not many other archs.  It looks like the
+solution may be to work on the ffmpeg build so it uses the
+BUILD_SHARED flag to use -fPIC and build shared lib for libavformat
+too.  Yuck."
+
+Attached is a partial patch.  This will build libavcodec as a shared lib. 
+However, libavformat is still setup to build as a static lib.  Further work
+is needed to build that shared too.
