[Insight-developers] Video and OpenCV issues

[Luis Ibanez]

Bill,

We made some progress with Xiaoxiao,
and push a patch 4:

Where the ITK_VIDEO_USE_*
variables were part of the problem,
http://review.source.kitware.com/#patch,sidebyside,2997,4,Modules/Video/IO/src/itkVideoIOFactory.cxx

but,...
still need to do further debugging.

We think that we are getting closer
to the final source of the problem.
