Hi all !

  After calling avcodec_decode_video from an interlaced video file I get a
valid filled AVFrame structure : interlaced_frame and top_field_first
AVFrame's values are set to 1.
  How do I get the top field ? From line 0, 2, 4, 6, 8 ? And bottom field ?
>From line 1, 3, 5, 7,... ?

  Thanks in advance...

  Thomas.P
