OMP is an open-source music player being developed for Linux. It is programmed in C++ and some C using gtkmm3, GStreamer, TagLib, libconfig, libclastfm, and standard C and C++ libraries. It can play mp3, FLAC, Ogg, Ogg FLAC, ALAC, APE, and AAC(m4a container) files gaplessly and stores tracks in a database.
OMP is currently in an unfinished state, which means it is missing key features. Check the Projects Page on OMP’s GitHub to see planned features.
