Hi,
According to the Windows sample HolographicFaceTracking https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/HolographicFaceTracking, 'The HoloLens PV camera provides NV12 video images by default'. However, it seems that on your app, you acquire frames with BitmapPixelFormat Bgra8. How do you do that ?
Thank you for your help.

If you take a look at issue #19, you can see that it really does not work well. OpenCV does support data crushing though, if you really need that to happen.

Take a look at MediaFrameSourceGroup::GetSubtypeForFrameReader -- we are requesting the images to be converted to Bgra8.
