Notes

This filter is automatically invoked by the loader as part of image normalization. It compares the frame property top_field_first to the consumer property with the same name to determine if correction is needed. It performs field order correction by shifting the image down by one line. If you set the property meta.swap_fields=1 on the producer, then this filter swaps the fields of an interlaced frame in addition to any field order correction by shifting the image.
