someone did this？please give me some information！ Thanks

Hello,

When I output a texture/FBO, the colors are correct in the window on Mac OS but the red and the blue colors are inverted on the SDI output/monitor (I made the verification with a color bars pattern).

I haven't found the way to change the pixel format (BMDPixelFormat?) in the ofxDeckLinkOutput class.
Is there a setting to change on my output object so the Decklink outputs the colors in the right order?

Here is my system in case this helps :

• MacPro4,1 + Mac OS 10.9.5
• DeckLink Studio 4K
• Blackmagic Desktop Video 10.5.4

Thanks

Thank you for your work on ofxDeckLink. The add-on works fine in YUV mode, but I cannot get (RGB or ARGB) values from the data coming from the Blackmagic.

The call for Input.setup() is:
bool start(BMDDisplayMode mode = bmdModeHD1080p30, bool use_rgb_colorspace = false);

If I leave the use_rgb_colorspace as false, I can draw the data to screen, but I can't access the pixels properly because the format is YUV. If I set use_rgb_colorspace as true, I see only black on the screen.

Is there another way to enable RGB for the add-on?

Blackmagic UltraStudio Mini Recorder
Decklink SDK 10.8 (also tried 10.9)
openFrameworks 0.9.8
OS X 10.12.6
MacBook Pro

I am trying to use this addon in a windows environment and cant seem to get it to compile. It fails due to not having CoreFoundations. Has anyone had any luck getting this working?
