Following the instruction:
http://ubuntuforums.org/showpost.php?p=9868359&postcount=1289 , I have
installed the   FFmpeg libraries in my Ubuntu system. At the beginning, it
seems to be fine. When I tested the libraries with the example program :
"libavcodec/api-example.c", an error message :
undefined reference to `avcodec_decode_video2'
will be shown in the project building process.

Does that mean what I installed is an old version of FFmpeg?

I am appreciated for any help.
