RFC 5334 Ogg Media Types September 2008
1. Introduction
This document describes media types for Ogg, a data encapsulation
format defined by the Xiph.Org Foundation for public use. Refer to
"Introduction" in [RFC3533] and "Overview" in [Ogg] for background
information on this container format.
Binary data contained in Ogg, such as Vorbis and Theora, has
historically been interchanged using the application/ogg media type
as defined by [RFC3534]. This document obsoletes [RFC3534] and
defines three media types for different types of content in Ogg to
reflect this usage in the IANA media type registry, to foster
interoperability by defining underspecified aspects, and to provide
general security considerations.
The Ogg container format is known to contain [Theora] or [Dirac]
video, [Speex] (narrow-band and wide-band) speech, [Vorbis] or [FLAC]
audio, and [CMML] timed text/metadata. As Ogg encapsulates binary
data, it is possible to include any other type of video, audio,
image, text, or, generally speaking, any time-continuously sampled
data.
While raw packets from these data sources may be used directly by
transport mechanisms that provide their own framing and packet-
separation mechanisms (such as UDP datagrams or RTP), Ogg is a
solution for stream based storage (such as files) and transport (such
as TCP streams or pipes). The media types defined in this document
are needed to correctly identify such content when it is served over
HTTP, included in multi-part documents, or used in other places where
media types [RFC2045] are used.
2. Changes Since RFC 3534
o The type "application/ogg" is redefined.
o The types "video/ogg" and "audio/ogg" are defined.
o New file extensions are defined.
o New Macintosh file type codes are defined.
o The codecs parameter is defined for optional use.
o The Ogg Skeleton extension becomes a recommended addition for
content served under the new types.
