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.
