How to set the path in Linux

Help when I do 'ffmpeg', I get

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

However, when I do LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib ffmpeg, I get 

FFmpeg version SVN-r26402, Copyright (c) 2000-2011 the FFmpeg developers

Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

Use -h to get full help or, even better, run 'man ffmpeg'

Can someone tell me how to set this permanently. I am a newbie to the linux command window. I saw something about editing the /etc/ld.so.conf file, but I don't know how to do that exactly. Any help will be appreciated

Edit one of these files:

  1. /etc/profile
  2. ~/.bash_profile
  3. ~/.bash_login
  4. ~/.profile

And add: LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib ffmpeg

Then reboot

You can set 

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

in your .profile or .bashrc file (depending on the shell you're using). That way it'll get set for each shell process you open.

This modification will be particular to you. Editing the /etc/ld.so.conf file is a system-wide modification.
