Trouble compiling Pyffmpeg 2.2a on Windows for Python 2.7

[dsch...@gmail.com]

Hi all,

I'm trying to compile the newest version of pyffmpeg (2.2 alpha) for Windows, as I there doesn't seem to be a distro for Python 2.7.

After having solved some initial problems:

1) On r78 of setup.py, I had to adapt libinc variable to not append "\include" to the ffmpeg dir.

2) Again on r78, I had to change the incdir from a string  type to a list (otherwise you get an error msg you can't concatenate string and list).

3) The compilation then fails because gcc can't find libavutil/avconfig.h. This file has been gone for quite a while now in ffmpeg. I did find its contents on http://opendvs.googlecode.com/svn-history/r6/trunk/dvs/ffmpeg/libavutil/avconfig.h, so I added this file myself.

 
After that, the compilation process goes into a frenzy, and I get some many error messages I don't know where to start to solve them. Here's the output:

running install

skipping 'pyffmpeg.c' Cython extension (up-to-date)

Is there anybody who's been succesfully able to compile pyffmpeg for windows of could offer me any help with this?

What I think  are seeing is an offshoot of pyffmpeg being built against a very specific version of FFmpeg.  Seeing "deprecated" show up is a good inidication of a version issue. 

FFmpeg is a well maintained and rapidly developing product and the installation makes 

no determination on what version of ffmpeg is already installed on the box. Was this an oversight or was this supposed to be version agnostic ?

Thanks

Hi:

   I've been encounter the same problem when build the pyffmpeg2.0 on Ubuntu 11.10, but I finally compile it successfully. Though the environment may be different, but the

   following steps may helps you:

      1. You need to replace some strings in file pyffmpeg.c:

             replace all 'CODEC_TYPE_AUDIO' with 'AVMEDIA_TYPE_AUDIO'

             replace all 'CODEC_TYPE_VIDEO' with 'AVMEDIA_TYPE_VIDEO'

 

      2. Commented some code lines in file pyffmpeg.c:

             all code lines include 'CodecCtx->hurry_up ....' should be commented

 

      3. You also need to replace some strings in file pyffmpeg.py:

             (some places according to compile error messages)

              replace the '__init__' with '__cinit__'

 

      Now try again.

      Hope it can helps you.
