Re: Video package not working

[Nasreen P]

Sir,

  I am not familiar as much with the octave and it is new to me,so I really confuses with the code you are sent.I am using ubuntu 14.04 version and octave 3.8.1.I am actually doing video color transferring with respect to a reference image.so I am converting the video in  to different frames,then copying the color of reference image to each frame.But the color transfer in the case of image is successful.But i can't do it for video.If you help me in coding in octave please inform and it will be very helpful for my education and future.If I put my system in team viewer ,may you help me in coding? waiting for you replay.

Thank you

Nasreen P

Dear Developers,

I am working on my academic project and I want to convert the Matlab

project

in Ocatave. I tried to read the video in octave and it is showing error

always.

Libaavformat missing error.

It sounds like you are missing avformat library?
What version of octave are you using? What OS.

Is using the video package in octave, it appears in the unmaintained list,
which probably will mean that that the state of the package may not be good.

I tried to build the current video repository on Debian wheezy (stable) with one patch that remove the deprecated allocator:

hg clone http://hg.code.sf.net/p/octave/video octave-video
sudo apt-get install libavformat-dev libswscale-dev
cd octave-video/src
./bootstrap
./configure
make

After that the tests in addframe.cc:, avifile.cc, aviread.cc runs fine
