Hey,
I`m trying to capture video from ARRI Alexa camera. to get correct preview or record to arriraw I have to extract metadata from VANC (lines 9 - 11).
if I enable video as single sdi (bmdVideoInputFlagDefault) I can see and extract correct metadata from VANC. but single SDI means that I receive just half of frame and when I enable input as dual 3d (bmdVideoInputDualStream3D) ANC values always 64 - Luma and 512 - Chroma what means ANC OFF.
Is this correct behavior? do I need to set any flag to have proper vanc in dual mode?
Kind Regards,
Alex
