Can you tell CUDA which field to keep when Deinterlacing? Then, with two instances of DGAVCDecodeNV, one could hack together a CUDA bobber.
Code:
a=DGAVCDecodeNV_AVCSource("00001_NV.dga", deinterlace=true, order=1)
b=DGAVCDecodeNV_AVCSource("00001_NV.dga", deinterlace=true, order=0)
Interleave(a,b)
