If after compiling FFMPEG on Fedora you get the following error message, it can be fixed quite simply:
ffmpeg: error while loading shared libraries: libamrnb.so.3: cannot open shared object file: No such file or directory
First go into the following directory
cd /etc/ld.so.conf.d
Create a file a new file with an editor of your choice called : custom-libs.conf
Inside that file add the following line and save:
/usr/local/lib
Next exit your editor and type:
ldconfig
FFMPEG should now run problem free.
Thanks for that mate! worked like a dream.
