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.
