Hi

I am trying to install the ffmpeg library to work with the vipr external (http://ben.musicsmiths.us/vipr.phtml), and when I placed the avutil-51.dll file into C:WindowsSYSWOW64, it gives me this error:

codec#0: Max.exe - Entry Point Not Found The procedure entry point av_image_copy_to_buffer could not be located in the dynamic link library avutil-51.dll

How can I fix it?
