wondering if you could explain a little bit more though.  Sorry, I'm
very much an octave and Matlab newbie, so my knowledge of this stuff is
scarce.  When you say to "try the hg repo" what do you mean?  I went to
that link and it has a bunch of different files.  I went into the src
folder and there are a bunch of files there too.  I'm not sure what I
need to download from there.  Would you mind explaining a bit more?  Do
I need anything from that link? or do I just install ffmpeg,
libavformat-dev, libswscale-dev, liboctave-dev (for mkoctfile) and then
run your patch there?

I never build octave or an octave-forge package for windows so I won't
be a help here. Btw, for windows there is AFAIK a MinGW build, a MSVC
build, a cygwin and a experimental MXE build.

But as I can see from the octave wiki
http://wiki.octave.org/Octave_for_Windows#Octave-3.6.4-mingw_.2B_octaveforge_pkgs
there should be a working video package with Octave-3.6.4-mingw and
octaveforge pkgs.

So my suggestion for you is:
Try to install
http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.4%20for%20Windows%20MinGW%20installer/
read the Octave3.6.4_gcc4.6.2_sourceforge_readme.txt thoughtfully and
install the forge packages. You should then have also a working video
package.

Hope that helps, Andy
