[FFmpeg-user] Changing scan type (progressive<->interlaced) without reencoding.

As the title says, is this at all possible? My concern is mostly with mpeg2
and h264 that have content of one type but encoded/marked as another. Most
notably content that has progressive video but stored interlaced. So I'm
probably talking about a bit stream filter here because just setting the
"field_order", "top" etc. flags when rewrapping does nothing.But I have not
found anything in the official docs that suggest this is currently possible
so it would be nice if some of you developers could shed some light on this.
