Joining the conversation, as I had to patch this too to get mediakit to
build ;)

This is not only Debian, but also Gentoo, Arch and every future
distribution release that will include a ffmpeg snapshot that more recent
than march 2008 (afaik that was when the switch was made)
The ffmpeg project has reorganized their include paths, using separate
subdirectories for every sub libraries.
So libavformat headers are in .../libavformat, libavcodec ones in
.../libavcodec, etc
Usual fix to work on both current ffmpeg and old one is to check for
libavcodec/libavcodec.h at configure time, cache the result (config.h or
something like that) and include depending on it libavcodec.h or
libavcodec/libavcodec.h. sox for example behaves like that.

pkg-config returning only "-I/usr/include/ffmpeg" instead of something like
"-I/usr/include/ffmpeg/libavcodec -I/usr/include/ffmpeg/libavformat .." is
not a packaging problem, upstream designed it so. Many projects depending
on ffmpeg have updated to the new include paths (xine, vlc, blender, ...)
Anyway here after a quick sed line mediakit compiles fine ;)
sed -i -e "s#avcodec.h#libavcodec/avcodec.h#" \
-e "s#avformat.h#libavformat/avformat.h#" \
MKMediaFile.h
