Artem, you are probably right, but it was really a one-liner:



But either case, I guess the user will probably still need to take a
look at the description to understand how to "avoid specifying" the
vid_hdr_offs ;-)
So no real benefit supporting ",,"
Bit more intuitive, though.

Anyways, saw you already pushed, thanks.

We have 0 as the default value already, no need to have the second way
to specify the same.
