Hi,

I have a couple more questions :

1. It looks like we output two frames for every input frame/field if 
mode is 1 or 3, else we output a single frame. Is this right?
2. The mplayer code has a correct_pts variable that seems to allow 
doubling of frame rate. Here is it safe to assume this is always 
allowed/true?
3. If I add a 'fields' member to AVFilterPicRef struct, how do I make 
sure it will be set to the right value (i.e. TOP_FIRST etc)?

Thanks
