Hi Vitali, well luckily cuda saved me from having any penalties - since i do rgb to nv12 on cuda it actually does not matter if take the pixels from top or from bottom:D If I manage to get our university to a stable spot then (currently I am experiencing hangs with Windows 10 and the OpenGL redirection but I wont bother anyone here till I've gathered some adequate evidence) yeah, I can try to provide a patch for this:) As I said, it is simply an inconvenience not a show stopper so I can live with this.
