OK. I am not a ffmpeg developer and don't know anything about the patch. I 
only suggested 

  "The following allows ffplay to run:

  cd /usr/local/lib
  ln libavformat.so libavformat.so.50
  ln libavcodec.so libavcodec.so.51
  ln libavutil.so libavutil.so.49"

to demonstrate the scope of the failure and to provide a workaround to users 
who came across the same problem.

I have given the following information: 

  "After I have compiled ffmpeg using shared libraries and run make install, I 
  get the following error [when I try to run ffplay]:

  ffplay: error while loading shared libraries: libavformat.so.50: cannot open 
  shared object file: No such file or directory"


  "[I am using] Ubuntu 5.10. ldconfig -V reports:

????????ldconfig (GNU libc) 2.3.5 
????????Copyright (C) 2005 Free Software Foundation, Inc.

  In response to the other email, "make install" was run as root."

As suggested by M?ns Rullg?rd, the problem does not occur if I 
put /usr/local/lib in /etc/ld.so.conf.

Is there any further information that would be of use?
