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.
