The Dmapd project provides a GObject-based implementation of DMAP sharing. Dmapd features support for both DAAP (iTunes) and DPAP (iPhoto), support for realtime transcoding of media formats not natively supported by clients, and support for many metadata formats, such as those associated with Ogg Vorbis and MP3 (e.g., ID3). It has been used on OpenWrt Linux-based systems with as little as 32MB of memory to serve music, video, and photograph libraries containing thousands of files.
