amit's comments were extremely useful for me.
Also had to change line #22 at setup py for:
Extension("pyffmpeg", ["pyffmpeg/pyffmpeg.pyx"],
Got the same 6 compilation warnings.

needed to install libswscale-dev as well and found GetFrameTime() at line 631.
Thanks for pointing the stuff out.

pyffmpeg-read-only will cause:
/pyffmpeg.pyx:0:0: 'pyffmpeg-read-only.pyffmpeg' is not a valid module name
So don't do that. do mv pyffmpeg-read-only/ pyffmpeg
sudo apt-get install ffmpeg libavcodec-dev libavformat-dev libavutil-dev
python-dev
python-pyrex libswscale-dev libbz2-dev checkinstall
2) don't verify that /usr/include/ffmpeg was created (it isn't on my box, but
still work)
3) in "pyffmpeg.pyx", line #631 change the var type of "timestep" from type
"float"
to "int64_t", so that the function header would be:
def GetFrameTime(self,int64_t timestamp):
python setup.py build
sudo checkinstall python setup.py install

On modern Ubuntu Linux boxes,
For compiling the beta
The following packages are required :
* libavcodec-dev libavformat-dev libavutil-dev python-dev libswscale-dev
libbz2-dev
* python-PIL python-numpy
* Cython
If you have problem during the "cythonization" :
Try with the latest version of Cython.
Ubuntu Cython distribs were sometime a bit outdated.
There are still many warning while compiling the beta.
Please, let us know.

The Python Imaging Library (PIL) package name under Debian/Ubuntu is
python-imaging not python-pil.

Trying to install the new beta:
OS: Ubuntu 10.04 (Lucid)
Cython ver: 0.12.1 (latest version for today)
- All dependencies listed above are met.
- Turkish locale! Forgive me if I had to do something else prior to compilation.
Here's the output:

Hmm, I had a look at my development version, there is apparently no strange
character in the source.
Can you have a try with this latest version :
git clone "http://github.com/tranx/pyffmpeg.git/"
git checkout origin/beta
I believe I will update this release as pyffmpeg2 soon.

I tried with the latest git version; still the same.

Sorry, please don't take into consideration my previous comment as the branch
didn't actually change to origin/beta for my first attempt.
It could compile it successfully using the latest version.
Thank you.

Ok great, so I will update the package during the week, so that other users
don't face this bug. Feel free to ask more questions, if you have other issues
with the package.

Hi, I tried to compile pyffmpeg 2.1.beta on Ubuntu 8.04 with Cython 0.14, but I
always get the following error:
...
File "... /python2.5/site-packages/Cython/Compiler/TypeSlots.py", line 100, in fixed_arg_type
return self.format_map[self.fixed_arg_format[i]]
KeyError: 'T'
Does anyone know how to solve this error?

Hmm ,this is somehow an "internal compiler error", so this means that something
happened in the source code that was unexpected. My intuition, is that
generally Cython 0.14 users are on using python 2.6/2.7, and maybe there is
some unnoticed bug in-between python 2.5 and cython 0.14, I would try compiling
with older version of Cython, (or upgrading my python... but this is larger
operation)
It is also possible that there is something awkward in the source code of
pyffmpeg, but I cannot tell you if I don't know where the compiler crashed in
the source code...
'T' is supposed to be the key for the type for the self keyword in python.

This is a known problem that has already been reported but is still not fixed
in the trunk: http://code.google.com/p/pyffmpeg/issues/detail?id=33
It's a bug in pyffmpeg and sort of in Cython. The use of __new__ instead of
__cinit__ has been deprecated for years and Cython till 0.13 issued a warning,
but went on happily. Problem is, you normally don't see warnings with Cython.
From 0.14 on this fall back behaviour isn't supported any more, but Cython
still only issues a warning but doesn't raise an error. This ultimately leads
to the error above and you have no clue what initially went wrong from the
error message presented. Oh, by the way this is also a known issue for Cython
0.14 and hopefully someone fixes it.
