Hi all,
I've a playout software, based on the GMFPlay example, that, of course, plays
some mpeg2 video clips.
Depending on the edit software, I can obtain an upper field first or a lower
field first clip.
I have to play that clips through a decklink card and I need to be able to
play in the right way all the clips I have.
There is a way to do this, without re editing all the clips?
Thanks in advance... Maurizio
