|
| 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 https://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 [http://www.tech-chat.de/files/video-1.2.1_win_ffmpeg.tar.gz video-1.2.1_win_ffmpeg.tar.gz (sha1sum 3ef5b0dca471175daf769bd813b6de7fa85759df)]
| |
| or grab the source and apply [http://www.tech-chat.de/files/video-1.2.1_win_ffmpeg.patch this patch]
| |
| | |
| Compile and install from Octave with
| |
| <code>
| |
| pkg -verbose install video-1.2.1_win_ffmpeg.tar.gz
| |
| </code>
| |
| | |
| Load it before any usage:
| |
| <code>
| |
| pkg load video
| |
| </code>
| |
| | |
| === mxe-octave ===
| |
| You can also use mxe-octave to include ffmpeg, there is already a target for it.

| = Known bugs = | |
| * On MXE-Octave with ffmpeg crosscompiled "clear all" after using "addframe" causes a segmentation fault
| |
|
| |
|
| <code>
| | 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.
