Determining the line stride for the alpha plane for NDIlib_FourCC_type_UYVA

How do I know what the line stride for the alpha plane is for NDIlib_FourCC_type_UYVA format, since it'll be a different stride than the YUV plane. Should I assume it's always tightly packed?
Thanks
 
I do not think it is safe to assume Alpha is always tightly packed. I believe the Alpha plane would use (stride / 2), similar to the chroma planes in the YV12 format.
