GetAvailableVideoFrameCount() always returns 0
Posted: Thu Feb 15, 2018 10:36 pm
I am developing a machine vision application on OS X using an Intensity Extreme for capturing HDMI frames.
It turns out that IDeckLinkInput::GetAvailableVideoFrameCount() always returns 0. I hoped to use this method to skip frames when processing can't keep up, but now i have to find another way to achieve that. Is this a known issue in the driver or am i misunderstanding the purpose of this function? Will it only work with some specific capture devices?
