<p>
|
||
No configuration is required if you intend to run everything on a single
|
||
machine, and if you acquired Ardour from
|
||
<a href="http://www.ardour.org"
|
||
title="http://www.ardour.org">http://www.ardour.org</a>.
|
||
Everything is pre-configured and included with the download/install.
|
||
</p>
|
||
|
||
<h2>Single Machine</h2>
|
||
<p>
|
||
If you compile Ardour from source, or have installed it from a 3rd party
|
||
repository, three additional tools will need to be installed manually,
|
||
which are used by Ardour to provide video features:
|
||
</p>
|
||
<ul>
|
||
<li>xjadeo (the video monitor application): <a href="http://xjadeo.sf.net"
|
||
title="http://xjadeo.sf.net" rel="nofollow">http://xjadeo.sf.net</a></li>
|
||
<li>harvid (a video decoder used for the thumbnail timeline): <a
|
||
href="http://x42.github.com/harvid/" title="http://x42.github.com/harvid/"
|
||
rel="nofollow">http://x42.github.com/harvid/</a></li>
|
||
<li>ffmpeg, ffprobe (used to import/export video, extract soundtracks and
|
||
query video information): <a href="http://ffmpeg.org" title="http://ffmpeg.org"
|
||
rel="nofollow">http://ffmpeg.org</a></li>
|
||
</ul>
|
||
<p>
|
||
Ardour requires xjadeo ≥ version 0.6.4, harvid ≥ version 0.7.0 and ffmpeg (known to work versions: 1.2, 2.8.2)
|
||
</p>
|
||
|
||
<p>
|
||
The Ardour development team is in control of the first two applications. ffmpeg
|
||
however can be a bit of a problem. To avoid conflicts with distribution packages,
|
||
Ardour looks for <code>ffmpeg_harvid</code> and <code>ffprobe_harvid</code>.
|
||
</p>
|
||
<p>
|
||
All four applications need to be found in <code>$PATH</code> (e.g.
|
||
<code>$HOME/bin</code> or <code>/usr/local/bin</code>). For convenience the
|
||
binary releases of harvid include ffmpeg_harvid and ffprobe_harvid, but if
|
||
your distribution provides suitable ffmpeg commands you can also just create
|
||
symbolic links:
|
||
</p>
|
||
<kbd class="cmd lin">sudo ln -s /usr/bin/ffmpeg /usr/bin/ffmpeg_harvid</kbd>
|
||
<kbd class="cmd lin">sudo ln -s /usr/bin/ffprobe /usr/bin/ffprobe_harvid</kbd>
|
||
<p>
|
||
Binary releases are available from ardour.org as well as an installer script:
|
||
<a href="https://github.com/Ardour/ardour/blob/master/tools/videotimeline/install_video_tools.sh"
|
||
title="https://github.com/Ardour/ardour/blob/master/tools/videotimeline/install_video_tools.sh"
|
||
rel="nofollow">install_video_tools.sh</a>.
|
||
</p>
|
||
<p>
|
||
The easiest way to install the video-utilities is by running the following
|
||
line in a terminal:
|
||
</p>
|
||
<kbd class="cmd lin">sh -c "$(curl -s -L http://git.io/tVUCkw)"</kbd>
|
||
|
||
<h2>Studio Setup</h2>
|
||
<p>
|
||
Please read the info in the previous section to familiarize yourself with
|
||
the tools involved first. Setting up a proper A/V post-production studio
|
||
can be a complicated task. As much as we streamline and simplify the
|
||
<em>single machine</em> setup, the <dfn>studio setup</dfn> is focused on modularity.

<li>TODO:</li>
|
||
<li>Synchronization ardour → video-display-box should be accomplished by external
|
||
means jack-transport(netjack), MTC, LTC
|
||
(<abbr title="Open Sound Control - "postmodern MIDI"">OSC</abbr> and/or
|
||
ssh-pipe work but introduce additional latency + jitter)</li>
|
||
<li>Ardour launches <code>XJREMOTE</code> (environment variable, default 'xjremote' which comes with xjadeo).
|
||
</li>
|
||
<li>Either use a custom shell script that ssh'es into the remote box and launches/controls xjadeo there, selects the sync-source and passes though communication between ardour ⇔ xjadeo via ssh (xjadeo is launched stopped with the session).
|
||
</li>
|
||
<li>..or override xjremote's behavior – instead of IPC with a local running xjadeo-process, using <abbr title="Open Sound Control - "postmodern MIDI"">OSC</abbr> for example. xjadeo would run permanently and Ardour will just tell it to load files and set offsets via <acronym title="Open Sound Control - "postmodern MIDI"">OSC</acronym>. see <a href="http://xjadeo.git.sourceforge.net/git/gitweb.cgi?p=xjadeo/xjadeo;a=blob_plain;f=contrib/xjremote-osc" title="http://xjadeo.git.sourceforge.net/git/gitweb.cgi?p=xjadeo/xjadeo;a=blob_plain;f=contrib/xjremote-osc" rel="nofollow">xjremote-osc</a> example script.
|
||
</li>
|
||
<li>If the video server runs remotely, Ardour needs to be configured in Ardour > Preference > Video (hostname of the video-server).
|
||
</li>
|
||
<li>
|
||
Ideally the machines have a common shared folder (NFS or similar). Ardour's import (audio-extract) and export (mux) functionality depends on having access to the video file. Also Ardour's video-import transcodes the file into a suitable proxy-format that allows reliable seeking to any frame…
