[Ffmpeg-devel] error while loading shared libraries: libavformat.so.50

[P. W.]

Hi,

I am new to ffmpeg programming. As the first step, I
started playing with the sample code from

http://www.inb.uni-luebeck.de/~boehme/avcodec_sample.0.4.9.cpp

I have the code compiled and built successfully on my
Linux Fedora Core 4 box. But when I run it using:

#./avcodec_sample.0.4.9 myvideofile.mpg

It produces the following error:

./avcodec_sample.0.4.9: error while loading shared
libraries: libavformat.so.50: cannot open shared
object file: No such file or directory

Can anyone provide a explanation of the cause of this
error and how to fix it?

Thanks,

PW
