how do you know its upside down? did you view it in gdb, a hexeditor
mplayer, ffplay?

and how does imgresample/convert behave?

also DONT use anything microshit related to test that, as avi&asf do
have randomized vertical orientation for raw formats (not strictly true
MS has written a clear and totally senseless set of rules)

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
