[FFmpeg-devel] Interlaced video decoder help needed

I've decided to extend lavc VC-1 decoder to handle at least some of
interlaced video stuff. Looks like format with two fields is most
common so I'm going to implement it first.

How can I make decoder handle field-interlaced video (modify strides for
it, handle macroblock/draw_slice() stuff etc)? Finding answers in
mpegvideo.c probably will double amount of work.
