ardour-harvid-bin (ardour video tools) If Ardour is compiled from source, or installed from a 3rd party repository, three additional tools will need to be installed manually, which are used by Ardour to provide video features and allow direct export your session to mp3. For video support Ardour requires - xjadeo ≥ version 0.6.4 (available in SlackBuilds.org), - harvid ≥ version 0.7.0 and - ffmpeg (known to work versions: 1.2, 2.8.2, 5.0) The last two are made available by this package. To avoid conflicts with Slackware packages, Ardour looks for ffmpeg_harvid and ffprobe_harvid. If you only need mp3 export, xjadeo is not required.
