Network Working Group L. 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.

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 isShow full document text
