I've been looking at Apple's web and it seems that is not possible to
use quicktime api on Linux.
There are some free/open alternatives, e.g. libquicktime at
http://libquicktime.sourceforge.net/
I'm a linux user with no idea of api programming.
Is there any easy way to read/write frames with other programs and
then read the frames with octave?
You could use some program to convert the movie to a sequence of images
in whatever format you prefer.
I'm afraid I can't provide a pointer to such a program for Linux, but
I'm sure there are a number of options.
If you can get hold of a Mac or a Windows machine, download Quicktime
and upgrade it to "Pro" version ($30). You can then do export a movie
as an image sequence.
I just need to do some simple calculations using every three frames on
a movie.
Well, once you have an image sequence, read it into octave and do
whatever you please. Octave-forge provides some additional functions
for reading images. See http://octave.sourceforge.net/index/ , look
under Image processing.

Your advice is truly appreciated. Thanks,
