Video package

From Octave
Jump to navigation Jump to search

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

on Debian Jessie using "pkg -forge"

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

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

mxe-octave 4.0.1-rc3

You could try octave 4.0.1-rc3 from http://alpha.gnu.org/gnu/octave/ which is in testing - it has the ffmpeg libraries already in it, with the previous version of video package, which could be updated with

pkg -verbose -forge install video

using official mxe-build and ffmpeg binaries

This 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 https://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

octave-video 1.2.2 tries to find avresample which isn't included in the builds. Either patch configure.ac (remove the AC_CHECK_LIB avresample), rerun ./bootstrap and repack or download this patched version and install with

pkg -verbose install video-1.2.2.tar.gz

Load it before any usage:

pkg load video
