Please explain how limiting to 8 lines could ever make any sense
whatsoever.
I'm not saying that it makes sense, I'm saying that it makes "more"
sense to crop a maximum value (eg. 8 lines which is the most common
case) independently of resolution and framerate, instead of having some
videos working up to 24 lines and some others up to 16 (like the
DesertStreet_Top-Bottom_1080p50_crop.264 sample I submitted).
But yeah, I agree it is not a very clean solution (feel free to call it
a dirty workaround) so it completely fine to drop the patch if it
doesn't meet the quality standards.

But realistically, if the encoder wants us to skip more, well, then
let's skip more. Maybe these are invisible MBs used as prediction (of
off-frame content) for future frames, e.g. in case of a zoom-out
scene? Maybe the encoder is playing magic here. Jason can probably
confirm that there are cases where this may be beneficial.

Annex B) as well as being a mandatory behaviour defined in the H.264/AVC
