History

This filter checks for interlaced video frames and marks these by preceding them with a custom downstream event (simply an empty structure called 'detectinter'). Subsequent (dynamic/adaptive) de-interlacing can then be done by a downstream de-interlacing filter that recognizes this custom mark, such as fields.
