couldn't find ffmpeg libraries

Hi there,
I compiled the code in Fedora 17 with 'make'. I then run some tests in README file.
I pass ./bin/ezvision --in=/home/cheng/builds/saliency-20120616/tests/inputs/ezframe#.pnm -T --out=display
However, when I tried to process movies, I got a core-dumped (see the details below). It seems the program couldn't find ffmpeg libs that is in /usr/include/ffmpeg in my machine.
[cheng@salsa ffmpeg]$ pwd
/usr/include/ffmpeg
[cheng@salsa ffmpeg]$ ls
libavcodec libavdevice libavfilter libavformat libavutil libpostproc libswresample libswscale
I modified configure.ac and changed ADDINC = "-I${source}" into this
ADDINC="-I${source} -I/usr/include/ffmpeg -I/usr/include/ffmpeg/libavcodec -I/usr/include/ffmpeg/libavformat -I/usr/include/ffmpeg/libavdevice -I/usr/include/ffmpeg/libavfilter -I/usr/include/ffmpeg/libavutil ....
but didn't work.
I wonder if anyone has suggestion for me to fix this.
Thanks,
czhang

Hi -
sorry about that, ffmpeg is quite hard to get to work because it changes all the time, so depending on which exact version you are running some adjustments are often necessary.
We usually have 2 tests for each library in configure.ac: one that tests for include files, and the other that actually compiles a little piece of code using the library. It looks like the second one may be failing in your case.
after you run configure, have a look at config.log and search for avcodec and similar. You will see which one failed. In configure.ac, search for AC_CHECK_LIB(avcodec
maybe the avcodec function we use in the small piece of test code does not exist in your version of ffmpeg, hence the code fails, and the configure script thinks ffmpeg is not installed.
