[FFmpeg-user] symbol lookup error: /usr/local/lib/libavcodec.so.51: undefined symbol: faacDecOpen

[Jim Shupert]

friends,
I have attempted to reinstall ffmpeg.
i now get the following with the simplest of commands

js at VidCmp-7:~$ ffmpeg --formats
ffmpeg: symbol lookup error: /usr/local/lib/libavcodec.so.51: undefined 
symbol: faacDecOpen

if this is an unlinked lib -- how do i resolve ?

i have ubuntu 8.04
I was using 
http://www.rorexperts.com/installing-ffmpeg-in-ubuntu-t889.html as a how to


i see i 'have' a libavcodec.so.51
type: Link to shared , location :library /usr/local/lib

link target libavcodec.so.51.55.0
and i have a libavcodec.so.51.55.0
/usr/local/lib

how can i resolve this?

maybe i should  try a diffrent how to...
maybe my problem stems from a previous install??- i was attempting to 
get the 'latest'
  ( i have heard that is a good idea )

is this a known bug ( i saw *something* on launchPad )

but basically how can i get going.

and there is this when doing

sudo apt-get install libavcodec-unstripped-51 libavdevice-unstripped-52 
libavformat-unstripped-52 libavutil-unstripped-49 
libpostproc-unstripped-51 libswscale-unstripped-0

Reading package lists... Done
Building dependency tree       Reading state information... Done
E: Couldn't find package libavcodec-unstripped-51

so is that is I am missing libavcodec-unstripped-51 ---?

note: i had added the repo of mediaubuntu.org  ( 87.98.242.110 )


Thanks for any assistance!
