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


* ffmpeg-20160105-git-68eb208-win32-shared.7z
On the Octave prompt:
* ffmpeg-20160105-git-68eb208-win32-dev.7z


Now
>> pkg install -forge video


* Extract the bin/*.dll from ffmpeg-20160105-git-68eb208-win32-shared.7z to C:\Octave\Octave-4.0.0\bin
== On Windows ==
* Extract include/* from ffmpeg-20160105-git-68eb208-win32-dev.7z to C:\Octave\Octave-4.0.0\include
  (You should now, for example, see C:\Octave\Octave-4.0.0\include\libavutil\version.h)
* 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
</code>
 
=== mxe-octave ===
You can also use mxe-octave to include ffmpeg, there is already a target for it.

The video package is part of the Octave Forge project and tries to implement the video functions from matlab. It should compile with ffmpeg and libav.

Installation[edit]

on Debian Jessie using "pkg -forge"[edit]

sudo apt-get install libavutil-dev libavformat-dev libswscale-dev libavcodec-dev

On the Octave prompt: 

>> pkg install -forge video

on CentOS Linux release 7.2.1511 (Core) with GNU Octave Version 3.8.2[edit]

yum install octave-devel
yum install libvorbis  yasm freetype zlib bzip2 faac lame speex libvpx libogg  libtheora  x264 XviD openjpeg15 opencore-amr
wget https://libav.org/releases/libav-11.4.tar.gz
tar xzf libav-11.4.tar.gz
cd libav-11.4
./configure --enable-pic
make -j 4

as root: 

make install

On the Octave prompt: 

>> pkg install -forge video

On Windows[edit]

The MXE builds >= 4.0.1-rc3 already includes the ffmpeg libs so video should run out of the box.
