Solve the "recompile with -fPIC" error when compiling OpenCV with FFMPEG

The error happens while one wants to compile OpenCV with FFMPEG on 64 bits linux. Adding the parameter "--enable-pic" is not enough. Both the --enable-shared and --enable-pic need to be included when configuring ffmpeg:

./configure --enable-shared --enable-pic

I have successfully compiled on Fedora 64 bits. Good luck.
