Build on Py35, Win64

Merged Administrator requested to merge github/fork/caspervdw/build-win64 into master

Created by: caspervdw

After some hours of tinkering (thanks @beville for the helpful notes in #156 (closed)), I got PyAV working on my Win64 laptop with Python 35, using the binaries from https://ffmpeg.zeranoe.com/builds/ .

Prerequisites

  • Python35 on Windows is compiled using MSVC14, which can be obtained from Microsoft for free in the 'Visual C++ Build Tools 2015'. Using setuptools>=0.24, compiling and linking worked out-of-the-box for me. See here for more info.
  • Both the shared (for running) and dev (for compiling) packages (link), extracted in the same folder (e.g. C:\ffmpeg). Make sure C:\ffmpeg\bin and C:\ffmpeg\lib and C:\ffmpeg\include exist.
  • Add the ffmpeg bin folder to the PATH environment variable (e.g. C:\ffmpeg\bin)
  • Install Cython (?)
  • git clone or download & extract PyAV source

Build

From within the PyAV source directory

python setup.py build_ext --inplace --ffmpeg-dir=C:\ffmpeg

or

set FFMPEG_DIR=C:\ffmpeg
python setup.py build_ext --inplace`

This builds PyAV against a specific build of ffmpeg. Changing the ffmpeg binaries will get you a DLL not found error on import.

Test

  • nosetests pass
  • PIMS nosetests pass

I would like to get the wheel on conda, but as it is compiled against a specific ffmpeg version, these libraries would ideally be included. I am not sure how to do that properly.
