I just tested this patch on Ubuntu 9.04. With a little adjustment it
works:
NEW_AVFORMAT_INCLUDE_DIR=`if [ -n $$(pkg-config --cflags-only-I
libavformat) ]; then\
^
^^
-n option must be removed here exactly as in the previous libavcodec
test, since pkg-config returns a new line and not a zero string when
the include path is /usr/include.
However I'm not sure to understand why the patch is needed, does the
current version refuses to build on your Debian system because the
explicit include
'ADDITIONAL_OBJCFLAGS += -I/usr/include/libavcodec -I/usr/include/
libavformat' prevents the header to be corrrectly searched in /usr/
include/ffmepg/libav*?
This GNUmakefile as it is was working for me on older Ubuntu systems
using the same include path as yours.

Looks far better than the current hack :-) I still need to test this
patch and the previous one on an old Ubuntu system though.
I think the comment with the Ubuntu bug reference should be moved to
MKMediaFile.m too since this problem is Ubuntu specific. Do you have
the same issue on Debian too?
Cheers,
Quentin.
