Suggested value of File Encoding (M128)

The following text is recommended for inclusion in the File Encoding (M128) element when the Encoding contains an MPEG-4 video encoded using the MP file format.

The content of the DocumentData element is an MPEG-4 video stream encoded in the MP file format. The file conforms to the following parts of ISO/IEC 14496 ‘Information Technology – Coding of audio-visual objects’, Part 1:2004 (including Amd 1: 2005 and Amd 8:2004), Part 2:2004 (including Cor 1:2004, Amd 1:2004, and Amd 2:2005), Part 3:2004, and Part 14:2003 (including Cor 1:2006). The file has been encoded using Base64, which is defined in IETF RFC 2045 ‘Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies’, Section 6.8 ‘Base64 Content-Transfer-Encoding’.

The following text is recommended for inclusion in the File Encoding (M128) element when the Encoding contains an MPEG-4 video encoded using the AVC file format.

The content of the DocumentData element is an MPEG-4 video stream encoded in the AVC file format. The file conforms to the following parts of ISO/IEC 14496 ‘Information Technology – Coding of audio-visual objects’, Part 1:2004 (including Amd 1: 2005 and Amd 8:2004), Part 2:2004 (including Cor 1:2004, Amd 1:2004, and Amd 2:2005), Part 3:2004, Part 10:2005, and Part 15:2004 (including Cor 1:2006, and Amd 1:2006). The file has been encoded using Base64, which is defined in IETF RFC 2045 ‘Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies’, Section 6.8 ‘Base64 Content-Transfer-Encoding’.

The following text is recommended for inclusion in the File Encoding (M128) element when the Encoding contains an MPEG-4 video, but it is not known if it is encoded using the MP or AVC file format.

The content of the DocumentData element is an MPEG-4 video stream encoded in the AVC or MP file format. The file conforms to the following parts of ISO/IEC 14496 ‘Information Technology – Coding of audio-visual objects’, Part 1:2004 (including Amd 1: 2005 and Amd 8:2004), Part 2:2004 (including Cor 1:2004, Amd 1:2004, and Amd 2:2005), Part 3:2004, and either Part 14:2003 (including Cor 1:2006) OR Part 10:2005, and Part 15:2004 (including Cor 1:2006, and Amd 1:2006).
