Description

I don't know if I'm missing it, or if it's out of focus for this plugin,
but I couldn't find a comfortable way to take a picture from a CaptureFrom* component,
like a *.snapshot method that follows the same workflow set for video, same output same processing etc.

I tried to force it by recording exactly one frame to img sequence but it's never too precise, taking 2 frames sometimes, and it creates a folder for each sequence.
