That's why videoparse was using a string and parsing it manually. Moving away
from that, and deprecating the original wasn't very nice here.

Ok. Clearly no one have used the strides and offsets, it's probably too hard to
use atm anyway. Was the frame-stride name discussed ? Cause cause stride really
means a line, making frame-stride pretty weird. It's in fact the frame-size or
buffer-size imho.
