DLNA/UPnP Linux Server with Coherence

Coherence is a DLNA/UPnP Media Server written in Python which exports local files or online media to UPnP clients. Coherence fetch the media files from several sources such as:

• Local applications media collections, like those from Rythmbox or Banschee,
• Audio-CD or DVB
• Online services like Flickr, last.fm, YouTube, Picasa Web Albums and other.

Other sources can also be added thanks to Coherence plug-in architecture. The media server supports transcoding (currently experimental) that is to convert media files in another format.

Coherence toolkit also contains other packages such as:

• Coherence-Config: a cross-platform GUI frontend for ‘Coherence’.
• Cadre: a picture DLNA/UPnP MediaRenderer which can display pictures from the local filesystem or from a MediaServer.
• Mirabeau: An application level proxy for UPnP devices which allows to share your UPnP content between two or more local networks over the Internet. It uses XMPP as a transport (work in progress).
• UPnP-Inspector:  a graphical UPnP Device and Service analyzer, and a debugging tool. Detected devices are displayed in a tree-view where actions can be called and state-variables be queried.
• Plugins or extensions for other applications to open them to the UPnP world via Coherence framework.  Totem, Nautilus, Rythmbox and Banshee are some applications that can take advantage of Coherence DLNA/UPnP framework.

The Coherence toolkit is known to work on various Linux flavors, BSD, (Open)Solaris and Windows. Since it is written in Python it is cross-platform and can be supported by different architecture such as x86, arm, mips, ppc etc..

Developers can also make use of Coherence framework as it provides a:

• SSDP server
• MSEARCH client
• Server and client for HTTP/SOAP requests
• Server and client for Event Subscription and Notification (GENA)
