Colorspace conversion DX11 - YUV to RGB

io · November 25, 2016, 7:26pm

So how to convert YUV to RGB in DX11? I tried the converter that comes with the Blackmagic Decklink DX11 plugin but it does not work.
Current case is Blackmagic ATEN 4K streaming to Datapath Vision E1s with OpenCV Videoin.

I implemented it but it does not work. We had an easy way out using an HDMI out from the PC. Anyway something that should be taken into account.
