LinuxQuestions.org - symbol lookup error: /usr/lib/libavcodec.so.51: undefined symbol: av

Hello again peeps

Can someone help me?

I am trying to run a program script, but every time I try to run it I get this:

Code:

symbol lookup error: /usr/lib/libavcodec.so.51: undefined symbol: av_crc04C11DB7

Can someone please explain what this error is, and how I can fix it?

So far, I think its a link problem???? but I am not sure. If I search for the file I get this:

Code:

lrwxrwxrwx 1 root root      21 2009-01-22 16:15 libavcodec.so -> libavcodec.so.51.40.4

lrwxrwxrwx 1 root root      21 2008-06-26 10:41 libavcodec.so.51 -> libavcodec.so.51.40.4

if I run a ldd on the script I get this output:
