Move implementation status details to wiki.xiph.org. 

More recent versions of draft-sheffer-running-code suggest referring
to a wiki. We'd like to try maintaining the implementation status
separately.

<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.

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.

<section anchor="impl-chrome" title="Chrome">
<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.

<section anchor="impl-gstreamer" title="GStreamer">
<t>
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.

<section anchor="impl-ffmpeg" title="FFmpeg">
<t>
The popular media framework and conversion tool FFmpeg implements
some of this draft.
End trimming is not implemented, so file durations are not exactly
preserved.
This implementation is open source.

similar to FFmpeg.

<section anchor="impl-vlc" title="VLC">
<t>
VLC is another widely deployed implementation of demuxing, decoding, and
playback support for this draft.
It supports metadata, multichannel, start and end trimming, the gain field,
live streams, seeking, chained files (though seeking does not work
correctly with chained files), and multiplexing with other streams (e.g.,
video).
Opus support was added in version 2.0.4, released on October 18, 2012.
This implementation is open source.

<section anchor="impl-foobar2k" title="foobar2000">
<t>
A popular Windows application, foobar2000 implements read, write, and playback
support for this draft.
It supports metadata, multichannel, start and end trimming, the gain field,
live streams, chained files, and seeking.
Opus support was added in version 1.1.14, released on August 17, 2012.
Encoding support is implemented using opusenc from opus-tools.
This implementation is closed source.

<section anchor="impl-rockbox" title="Rockbox">
<t>
Rockbox is an established alternative firmware for portable music players
(typically small, embedded devices) that implements demuxing, decoding, and
playback support for this draft.
It supports metadata, start and end trimming, the gain field, and seeking.
It does not currently support multichannel or chained files.
Opus is currently only supported in development builds, though it is scheduled
to be included in the next stable release (3.13).
This implementation is open source.
