Comment (by jeeb):

 Yes, since 4.4 the AVFrame's metadata is being correctly passed onto the
 encoder for autodetection, unlike earlier where you'd have to specifically
 specify things for the encoder separately (this goes the same way for
 various other video frame metadata as well). So in a sense, flagging the
 frames as they should be interpreted is the "proper" way :) .

 That said, I have found the issue why `-top` wouldn't work (the override
 was being applied before the autodetection was handled, and thus getting
 overridden by the autodetection). I have now posted a patch to fix that,
 but as far as I can see that would match what `-field_order` would do
 (`tt` for `-top 1` and `bb` for `-top 0`). So if there's still some issue,
 then it's something else?
