This is at the moment the preferred way for windows users and assumes that you've installed Octave from the official MXE build from https://ftp.gnu.org/gnu/octave/windows/ to the default path.

as root:
   −
Download the ffmpeg binaries for windows from ffmpeg.zeranoe.com/builds/. You need the "32-bit Dev" and "32-bit Shared" archive. These instructions were tested with
+
make install

* Extract lib/* from ffmpeg-20160105-git-68eb208-win32-dev.7z to C:\Octave\Octave-4.0.0\lib

Download a patched version (no pkg_config check for ffmpeg and PixelFormat -> AVPixelFormat) from [[Media:video-1.2.1_win_ffmpeg.tar.gz]]

Compile and install from Octave with
  −
<code>
  −
pkg -verbose install video-1.2.1_win_ffmpeg.tar.gz

You can also use mxe-octave to include ffmpeg, there is already a target for it.

* On MXE-Octave with ffmpeg crosscompiled "clear all" after using "addframe" causes a segmentation fault

The MXE builds >= 4.0.1-rc3 already includes the ffmpeg libs so video should run out of the box.
Program received signal SIGSEGV, Segmentation fault.
