error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

right, this error usually comes when ldconfig does not know where to search for the libraries, so, in order to help it out,  on my fedora/centos systems, i did the following:

cd /etc/ld.so.conf.d

add another file:  custom-libs.conf

inside, put :

/usr/local/lib

save,

then do ldconfig, et voila.

Enjoy
