-What follows is a brief summary of major implementations of this

- draft, and their status.

-Note that this section should be removed before final publication

- as an RFC as per <xref target="draft-sheffer-running-code"/>.

-<section anchor="impl-opus-tools" title="opus-tools">

<t>

-The initial development implementation of this draft was in the

- opusenc, opusdec, and opusinfo command-line utilties, part of the

- opus-tools package and repository.

-While still 'development' status (pre-1.0) these utilities are

- in active public use, and have shipped with some recent Linux

- distributions and in homebrew.

-Together they implement basic read, write and playback support of

- Ogg Opus files including metadata, multichannel, start and end

- trimming, the gain field, live streams, and chained files, but currently do

- not support seeking.

-This implementation is open source.

-<section anchor="impl-opusfile" title="opusfile">

-<t>

-The opusfile library is a separate implementation of this draft as a helper

- library for demuxing and decoding.

-Like opus-tools, it supports metadata, multichannel, start and end trimming,

- the gain field, live streams, and chained files.

-Its primary focus is efficient seeking, including over HTTP(S) and in chained

- streams.

-It currently does not create Ogg Opus files.

-This library is in early development and is not widely deployed, though several

- projects are currently using it, including xmms2, taglib, and cmus, and it is

- shipped in some Linux distributions and in homebrew.

-This implementation is open source.

-<t>

-The Firefox web browser is a widely deployed implementation of

- this draft.

-Basic playback support with the HTML5 &lt;audio&gt; element, including start

- and end trimming, the gain field, live streams, multiplexing with other

- streams (for, e.g., the &lt;video&gt; tag), and seeking, was added in

- Firefox 15, in production release starting August 28, 2012.

-Multichannel support was added in Firefox 17, in production release

- starting November 20, 2012.

-Metadata support was added in Firefox 18, in production release starting

- January 8, 2013.

-Chained file support (as streams only, with seeking disabled) was added in

- Firefox 20, in production release starting April 2, 2013.

-This implementation is open source.

-<t>

-Google's Chrome web browser has support for this draft with the

- HTML5 &lt;audio&gt; element in M25 and M26, the dev and

- canary channels respectively as of January, 2013.

-This implementation currently does not support end trimming, the gain tag,

- chained files, or the .opus extension.

-Both M25 and M26 require passing --enable-opus-playback to the executable

- to enable support at the time of this writing.

-This implementation is based on open source code in

- Chromium and WebKit.

-The GStreamer media framework includes an implementation of

- this draft.

-It supports metadata, multichannel, start and end trimming, the gain field,

- live streams, chained files, multiplexing with other streams (e.g., video),

- and seeking.

-Support was first added in early 2011, and is part of the 0.11 and 1.0.x

- releases.

-The code implementing this draft is in the gst-plugins-bad collection,

- which generally indicates unsupported and/or experimental code,

- despite its release status.

-This implementation is open source.
