--------------------------------------+-------------------------------------
 When trying to bundle libavcodec from ffmpeg with application and using
 install_name_tool one will get following error:

 install_name_tool: changing install names can't be redone for:
 MyApp.app/Contents/Frameworks/libavcodec.dylib (for architecture i386)
 because larger updated load commands do not fit (the program must be
 relinked)

 This can be fixed by adding following parameter to ffmpeg's configure
 options:
         --extra-ldflags=-headerpad_max_install_names

 After compiling ffmpeg again, install_name_tool can be used with
 libavcodec.dylib just fine.
