=== using official mxe-build and ffmpeg binaries === | |||
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. | |||
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 | |||
* ffmpeg-20160105-git-68eb208-win32-shared.7z | |||
* ffmpeg-20160105-git-68eb208-win32-dev.7z | |||
Now | |||
* Extract the bin/*.dll from ffmpeg-20160105-git-68eb208-win32-shared.7z to C:\Octave\Octave-4.0.0\bin | |||
* 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. | |||

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