Hmm, obviously we miss information on why it was not working.
Can you try to run python -v and to provide a trace of the imported modules,
as well as a log of what happened during the setup.py.

Can you try the new version of pyffmpeg ?

I'm getting this error too with the latest svn.

Refering to Issue 16,

This probably may be to the fact that you are trying to do the import from the
directory that contains
your import to "pyffmpeg".

The directory from which you are running python must not contain any of the 
following
"file" or "directory/file" :
  pyffmpeg/__init__.py 
  pyffmpeg/__init__.pyo
  pyffmpeg/__init__.pyc
  pyffmpeg.py
  pyffmpeg.pyo
  pyffmpeg.pyc
  pyffmpeg.so (if different from the one you want to work with !)

Once imported you may check the available symbols by doing :

import pyffmpeg
dir(pyffmpeg)

If you are in the wrong case it will return something like this :
  ['__builtins__', '__doc__', '__file__', '__name__', '__path__']

And you can then check at pyffmpeg.__path__ or pyffmpeg.__file__ to see that are
different 
from your system pyffmpeg.

A valid install will return you something like this :
>>> import pyffmpeg
>>> dir(pyffmpeg)
['AFFMpegReader', 'AVCODEC_MAX_AUDIO_FRAME_SIZE', 'AudioPacketDecoder', 
'AudioQueue',
'AudioTrack', 'FFMpegReader', 'Image', 'OUTPUTMODE_NUMPY', 'OUTPUTMODE_PIL', 
'PIL',
'PixelFormats', 'PyArray_DATA_content', 'PyArray_DATA_content_buffer', 
'Queue_Empty',
'Queue_Full', 'TS_AUDIO', 'TS_AUDIOVIDEO', 'TS_VIDEO', 'TS_VIDEO_PIL', 'Track',
'VideoStream', 'VideoTrack', '__builtins__', '__doc__', '__file__', '__name__',
'numpy', 'numpyarr_at', 'py_av_register_all', 'rwbuffer_at', 'sys', 'traceback']
>>> pyffmpeg.__file__
'/usr/lib/python2.5/site-packages/pyffmpeg.so'

Yeah i tried it in a directory outside of pyffmpeg.

I still get the message.

stream = pyffmpeg.VideoStream()
AttributeError: 'module' object has no attribute 'VideoStream'

Ok, 

Please tell us what the content of "dir(pyffmpeg)" on your system.

What does "pyffmpeg.__file__" return on your system ?

Maybe also:

import os
os.listdir(os.path.dirpath(pyffmpeg.__file__))

"dir(pyffmpeg)" gives:

['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']

os.listdir(os.path.dirpath(pyffmpeg.__file__)) gives

AttributeError: 'module' object has no attribute 'dirpath'

Ok just to make sure that directory wasn't doing anything I deleted the pyffmpeg
directory and now I get the old error back:

ImportError: /usr/local/lib/python2.6/dist-packages/pyffmpeg.so: undefined 
symbol:
av_reduce

Ok, good. 

Go back to issue 16 and give me the complete output of your 
"nm" commands.

[GoogleCodeExporter]

nm /usr/local/lib/python2.6/dist-packages/pyffmpeg.so|grep av_reduce
         U av_reduce
