How to install pyffmpeg on Ubuntu 8.04

[GoogleCodeExporter]

Since I am not a member of the project - take this with caution:

1) use Synaptic (or apt-get/aptitude) to install the following packages:
ffmpeg, libavcodec-dev, libavformat-dev, libavutil-dev, python-dev,
python-Pyrex

2) verify that /usr/include/ffmpeg was created

3) in "pyffmpeg.pyx", fix line #584 (arguments of function "GetFrameTime"),
namely, 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):

4) if you got here, you should not be editing anything else ... (unlike
other protocols in this project's post) just go to the project folder on
your machine

5) 'python setup.py build' (I got about 6 compilation warnings ...)

6) I use 'checkinstall' as an installation tool but it is not a must:
'sudo checkinstall python setup.py install'

7) enter whatever you wish when asked by checkinstall and there-you-have-it !

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Ubuntu Cython distribs were sometime a bit outdated.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.

[GoogleCodeExporter]

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.

ok thank you, with cython 0.12 it compiles fine.

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.
