Libdmapsharing is a library you may use to access, share and control the
playback of media content using DMAP (DAAP, DPAP & DACP). Libdmapsharing
also detects audio AirPlay services; coupled with the AirPlay support
in PulseAudio or GStreamer, this can allow an application to stream audio
to an AirPlay device. The library presently supports Linux and other
POSIX-based systems. It is written in C using GObject and libsoup. The
DMAP family of protocols are used by products such as Apple iTunes,
Apple iPhoto, and the Roku SoundBridge family to share media such
as music and photos.
