This is possible, but there's some issues, since our plugin may rely on
API that no longer exists in ffmpeg CVS. So we generally don't recommend
doing this. It's possible, however. If you have an external ffmpeg build
in /tmp/ffmpeg/, simply edit gst-ffmpeg/ext/ffmpeg/Makefile.am and
change the references to $(top_scrdir)/../libav*.la
to /tmp/ffmpeg/libav*/libav*.a. However, still, the above restriction

Most likely the recent separation of libavutil into its own lib in
ffmpeg CVS... I haven't updated gst-ffmpeg for that yet, I do have a new
autotools patch ready (available on request).

This information is in the ChangeLog file in gst-ffmpeg CVS.
