'''OpenCodecs''' is a software package for enabling [[HTML5 video]] on [[Microsoft Windows]], particularly using the [[Theora]] and [[WebM]] codecs in [[Internet Explorer]]. It consists of:
* ''dshow'', [[Xiph.Org Foundation|Xiph]]'s [[DirectShow]] filters for their suite of [[Ogg]] formats, including Theora and [[Vorbis]]
* ''webmdshow'', the DirectShow filter for WebM maintained by [http://www.webmproject.org the WebM project]
* An [[ActiveX]] plugin adding HTML5 video capability to Internet Explorer older than version 9
The DirectShow filters support all DirectShow applications (like [[Windows Media Player]]), not just Internet Explorer.
