Compile ffmpeg.c and call its main() via JNI

I have built FFmpeg on Android. I am trying to call the main() in ffmpeg.c via JNI and pass it the arguments it expects exactly how you would from the command line. When I added the ffmpeg.c file to my android.mk I got a couple errors which were easily fixed by commenting out the "#if HAVE_SYS_RESOURCE_H" line at the top which allowed a couple includes to be brought in. After this I now have undefined reference errors which all point to the "cmdutils.h" include. Here are just a few of my compilation errors...
