Not on the Intel model: IPU7 drops them, as you expect. With 0x0329 at
1, the test-pattern frames match those at 0 with no shift, and the top
rows hold image data, not the embedded lines.

On the Snapdragon model it runs the other way: George's stream stops
with the status lines off and runs with them on, and on 16/10 his
vd55g1 build streamed with them off. So I agree the register itself
should not matter there; something else in v1 probably does, and George
can narrow it down on CAMSS better than I can. v2 leaves the register at
its default, which changes nothing on IPU7.
