Hello!
I'm trying to experiment with ffmpeg for the iPhone and have run
into a snag.
I followed the installation instructions from here:
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html
After I did that I added the libavcodec.a to my project in xcode.
I also set my header search path to the folder where the libraries are.
It appears that I can compile and run on the iPhone simulator -
however when I compile for the actual device I get a linking error of:
Building target “VideoFun” of project “VideoFun” with configuration
“Debug” — (1 error)
cd "/Users/jmastro0517/Documents/iPhone Apps/VideoFun"

I've been beating my head against a wall for a week now and any help
is greatly appreciated.
Thanks, Joe.
