Disclosed is a device (200) for providing supplemental processing information relating to encoded media content. The device (200) includes an identifier provider (225) configured to provide a pseudo-identifier as an alias of a media codec (235) employed for encoding the media content. An information provider (225) provides supplemental processing information defining post-decoding instructions for processing decoded media content obtainable by decoding the encoded media content. A file organizer co-organizes the pseudo-identifier provided by the identifier provider (225) and the supplemental processing information provided by the information provider (225) in a file to trigger abortion of decoding of the encoded media content by a legacy media terminal that does not recognize the pseudo-identifier and enables decoding of the encoded media content using the media codec. The file organizer then post-decodes processing of the decoded media content using the supplemental processing information by a media terminal that recognizes the pseudo-identifier. The file organizer generates a media container file that has at least one media track defining the media content and at least one media data box comprising the encoded media content. The identifier provider (225) provides, in the media container file, a sample entry box defining the pseudo-identifier and provides, in the sample entry box, a media format box comprising a codec identifier of the media codec. The information provider (225) provides, in the sample entry box, a supplemental processing information box comprising the supplemental processing information. |
