I'm working on adding interlaced frame support for VC-1 and
has some question regarding AVCodecContext internals:
What do avctx->interlaced_frame, avctx->top_field_first
and avctx->repeat_pict affect if set by decoder?
And is it enough to set them and lavc will do the rest of work
or decoder also needs to output picture in standard format? 

As a side note: known EVO samples use progressive picture so
current decoder may be used for viewing.
