I had one (dumb?) question about yadif :
Since the PicRef structure in libavfilter has no 'fields' member,
how do I find out if the image data in the buffer is
MP_IMGFIELD_ORDERED, MP_IMGFIELD_TOP_FIRST etc. Is it indicated in
the PixelFormat?
Ehm no, I believe we need to add it to the AVFilterPicRef struct.
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
