No.

Afaict, our "flip" detection is generally wrong, not (or at 
least not always) should the encoder (in this case loco) 
trigger flipping images, but (at least in some cases) the 
encoder / muxing software - VirtualDub - is responsible for 
the upside-down picture.
This would also explain ticket #511.

(Yes, I usually absolutely refuse to commit patches I did not 
test before, I thought it better to omit "forgotten in r4097".)
