Installation requirements.

[M Armstrong]

Hello,

I’m relatively new to Python and pyffmpeg, however it looks like a
useful application for streaming mpeg video. Are there any
installation instructions/information available? do I have to use
Python2.6?, which version of ffmpeg should I install?

Any help would be appreciated.

Thanks in advance,

Marc.

Hi Marc, 

I haven't work on pyffmpeg for issues.

I am sorry there are a couple of known issues... expecially with modern version of cython.

Normally, you should be able to build with any version of python / ffmpeg, if you understand what building a C program means else... but this is maybe not true... and then you'd better keep to the prebuild.

I planned to set up a build bot to avoid that problems... did not have time so far...

Are you on MAC/ PC/ Win 32 /  Win 64 ?

Thanks for the email, I will try to add pyffmpeg to my buildbot.

Hi Bertrand,

Thanks for getting back so quickly. I am using Windows 7 and have
installed Python 2.6.6.

I have downloaded the following dlls
avcodec-52.dll
avcore-0.dll
avdevice-52.dll
avfilter-1.dll
avformat-52.dll
avutil-50.dll
swscale-0.dll

and installed them in my SysWOW64 directory.

I had to google and download these dlls individually, so am concerned
that they may not all be correct. Is there a known reliable source for
downloading ffmpeg? What is the ffmpeg version compatible with
pyffmpeg?

When I try to import ffmpegreader I get the following error (which has
been mentioned in another thread)

ImportError: DLL load failed: The specified procedure could not be
found.

Do I have to install PIL and numPy?

Marc.

I believe there are some build compatible... but I cannot be sure yet (They are quite old now).

Let's make it simple install all the ffmpeg dll in the windows/system32 directory (this is a bit brutal but this way you will be sure they will be found by python).

You can use some tool like "procmon" to check if a file is not found by python.

You need either PIL or numpy or both.

I recommend numpy.

At the moment I have been using the 32bit dlls and installed in
syswow64 - which is the 32bit directory. Just to clarify, should I
download the 64bit dlls and install in the system32 directory? -
bearing in mind the backwards meanings of the system32 and syswow64
folders in windows 7.

If so, which 64 bit version of ffmpeg should I download?

Regards,

Marc.

I have made some progress. I went to http://ffmpeg.zeranoe.com/builds/
and downloaded version ffmpeg-0.7.1-win32-shared. Copying the dlls to
the syswow64 folder gets rid of the error.

The problem appears to be that I was downloading the dlls individually
by googling given that pyffmpeg is not compatible with the latest
version of ffmpeg.

Thanks very much for your help.

Marc.
