+
+You will need to have mpeg4ip installed. If you install it on the same drive, with the top level directory
+name of /mpeg4ip, you will have to do nothing other than move the faad2_plugin.dll from the Release or
+Debug directory to the same directory as the other mpeg4ip plugins.
+
+If you install it somewhere else, you will have to change the include paths and link paths in the project
+settings for faad2_plugin to the proper directory. Look for /mpeg4ip (or \mpeg4ip) and change all occurances
+of these in the file.
+
+It might be best to hand-edit the faad_plugin.sdp file with wordpad and use the search and replace function.
