Walleij -Request for Comments: 3534 The Ogg Vorbis Community -Category: Standards Track May 2003 - - - The application/ogg Media Type - -Status of this Memo - - This document specifies an Internet standards track protocol for the - Internet community, and requests discussion and suggestions for - improvements. Please refer to the current edition of the "Internet - Official Protocol Standards" (STD 1) for the standardization state - and status of this protocol. Distribution of this memo is unlimited. - -Copyright Notice - - Copyright (C) The Internet Society (2003). All Rights Reserved. - -Abstract - - The Ogg Bitstream Format aims at becoming a general, freely-available - standard for transporting multimedia content across computing - platforms and networks. The intention of this document is to define - the MIME media type application/ogg to refer to this kind of content - when transported across the Internet. It is the intention of the Ogg - Bitstream Format developers that it be usable without intellectual - property concerns. - -Conventions used in this Document - - The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", - "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this - document are to be interpreted as described in RFC 2119 [2]. - -1. The Ogg Bitstream Format - - The Ogg Bitstream format has been developed as a part of a larger - project aimed at creating a set of components for the coding and - decoding of multimedia content (codecs) which are to be freely - available and freely re-implementable both in software and in - hardware for the computing community at large, including the Internet - community. - - Raw packets from these codecs may be used directly by transport - mechanisms that provide their own framing and packet-separation - mechanisms (such as UDP datagrams). - - - - -Walleij Standards Track [Page 1] - -RFC 3534 The application/ogg Media Type May 2003 - - - One such framing and content-separation mechanism is the real-time - transport protocol (RTP). RTP allows the streaming of synchronous - lossy data for broadcasting and similar purposes. If this function - is desired then a separate RTP wrapping mechanism should be used. A - wrapping mechanism is currently under development. - - For stream based storage (such as files) and transport (such as TCP - streams or pipes), Ogg codecs use the Ogg Bitstream Format to provide - framing/sync, sync recapture after error, landmarks during seeking, - and enough information to properly separate data back into packets at - the original packet boundaries without relying on decoding to find - packet boundaries. The application/ogg MIME type refers to this kind - of bitstreams, when no further knowledge of the bitstream content - exists. - - The bitstream format in itself is documented in [1]. - -2. Registration Information - - To: ietf-types@iana.org - - Subject: Registration of MIME media type application/ogg - - MIME media type name: application - - MIME subtype name: ogg - - Required parameters: none - - Optional parameters: none - - Encoding Considerations: - - The Ogg bitstream format is binary data, and must be encoded for - non-binary transport; the Base64 encoding is suitable for Email. - Binary encoding could also be used. - - Security Considerations: - - As the Ogg bitstream file is a container format and only a carrier of - content (such as Vorbis audio) with a very rigid definition (see - [1]), this format in itself is not more vulnerable than any other - content framing mechanism. The main security consideration for the - receiving application is to ensure that manipulated packages can not - cause buffer overflows and the like. It is possible to encapsulate - even executable content in the bitstream, so for such uses additional - security considerations must be taken. - - - - -Walleij Standards Track [Page 2] - -RFC 3534 The application/ogg Media Type May 2003 - - - Ogg bitstream files are not signed or encrypted using any applicable - encryption schemes. External security mechanisms must be added if - content confidentiality and authenticity is to be achieved. - - Interoperability considerations: - - The Ogg bitstream format has proved to be widely implementable across - different computing platforms. A broadly portable reference - implementation is available under a BSD license. - - The Ogg bitstream format is not patented and can be implemented by - third parties without patent considerations. - - Published specification: - - See [1]. - - Applications which use this media type: - - Any application that implements the specification will be able to - encode or decode Ogg bitstream files. Specifically, the format is - supposed to be used by subcodecs that implement, for example, Vorbis - audio. - - Additional information: - - Magic number(s): - - In Ogg bitstream files, the first four bytes are 0x4f 0x67 0x67 0x53 - corresponding to the string "OggS". - - File extension: .ogg - - Macintosh File Type Code(s): OggS - - Object Identifier(s) or OID(s): none - - Person & email address to contact for further information: - - Questions about this proposal should be directed to Linus Walleij - <triad@df.lth.se>.
