What is Rygel?
Rygel is a collection of DLNA[1] (UPnP[2] AV) devices, implemented through a
plug-in mechanism.
== Important facts and features ==
* Specifically designed for GNOME (Mobile) and is therefore planned to be one
of the key new features of Maemo[3] platform in the Harmattan[4] release.
* Based on GUPnP[5].
* Written (mostly) in Vala language[6]
* APIs to ease the implementation of AV devices (currently only MediaServer[7]
version 2.0 specification[8].
* Export of on-disk media:
* tracker[9] plugin.
* media-export plugin: Recursively exports folders and files specified in
the user configuration. This plugin supports all
types of URIs that gio/gvfs and gstreamer can handle.
* Export of online media from 2nd German TV station[11].
* Export of media hierarchies provided by external applications through
implementation of D-Bus MediaServer spec[12]. Applications that utilize
this feature are:
* PulseAudio[13]: Provides streams for input/output devices on the system.
* DVB Daemon[10]: Provides live TV (DVB) channel streams.
* Export of GStreamer pipelines as media items on the network, specified
through gst-launch syntax in the user configuration.
* Audio and Video Transcoding: source format could be anything GStreamer's
decodebin2 can handle but output formats are currently limited to: mp3, PCM
and MPEG TS. Fortunately the transcoding framework is flexible enough to
easily add more transcoding targets.
