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
