*[[Annodex]]&nbsp;– an encapsulation format, which interleaves time-continuous data with CMML markup in a streamable manner
*[[Icecast]]&nbsp;– an open source multi-platform streaming server (software)
*[[Icecast|Ices]]&nbsp;– a source client for broadcasting in Ogg Vorbis or MP3 format to an icecast2 server (software)
*IceShare&nbsp;– an unfinished peercasting system for Ogg multimedia (no longer maintained)

=== OpenCodecs ===
''OpenCodecs'' is a software package for Windows adding DirectShow filters for the [[Theora]] and [[WebM]] codecs. It adds Theora and WebM support to [[Windows Media Player]] and enables [[HTML video]] in [[Internet Explorer]]. It consists of:
* ''dshow'', Xiph's [[DirectShow]] filters for their suite of [[Ogg]] formats, including Theora and [[Vorbis]]
* ''webmdshow'', the DirectShow filter for WebM maintained by the WebM project
* An [[ActiveX]] plugin adding HTML video capability to Internet Explorer older than version 9

=== QuickTime Components ===
''Xiph QuickTime Components'' are implementations of the [[Ogg]] container along with the [[Speex]], [[Theora]], [[FLAC]] and [[Vorbis]] [[codec]]s for [[QuickTime]]. It allows users to use Ogg files in any application that uses QuickTime for audio and video file support, such as [[iTunes]] and [[QuickTime Player]].

Since QuickTime Components do not function in [[macOS Sierra]] and above, the project was discontinued in 2016.<ref>{{cite web |url=https://www.xiph.org/quicktime/ |title=XiphQT discontinued |date=13 June 2016 |website=Xiph.org }}</ref>
