[Libav-user] Reading field by field of an interlaced video

I want to estimate the motion between two fields of an interlaced
video. Currently I run a loop of av_read_frame() and
avcodec_decode_video2() to read the video. But I guess that when
avcodec_decode_video2() finishes reading a frame, it must have been
de-interlaced the two fields of a frame to the complete frame.
I have no idea how I can read field by field of the video. Please give
me some pointers to start with.
thanks in advance.
