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 Windows

You can use mxe-octave to include ffmpeg, there is already a target for it.

Known bugs

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

Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 1956.0xdd4] 0x77d6e3c6 in ntdll!RtlInitUnicodeString () from C:\Windows\SysWOW64\ntdll.dll (gdb) bt
