I have been trying to do this for hours, but have been unsuccessful.

I can compile the library into static library files (.a) without
issue, but I cannot link to them. My compilation just completely
ignores them. I've been searching for solutions for hours, like
-static and such. Nothing works! Only the old shared .so libraries are
recognized, using -lavcodec for example.

So I think, well why don't I compile ffmpeg as shared. I use this:
$ ./configure --enable-shared --enable-debug --disable-stripping

Which leads to my next problem, the error message:
LD	libavcodec/libavcodec.so.55
/usr/bin/ld: libavcodec/mqc.o: relocation R_X86_64_32 against
`.rodata' can not be used when making a shared object; recompile with
libavcodec/mqc.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
make: *** [libavcodec/libavcodec.so.55] Error 1

So I attempt to use
./configure --enable-shared --enable-debug --disable-stripping
./configure --enable-shared --enable-debug --disable-stripping

But neither stop the error about fPIC from occurring.

Any ideas?
