Users can browse by tags or directories and search with regular expressions, structured boolean logic or Python expressions. Its tag editor supports Unicode, batch changes and renaming files based on tags. Playback features include Replay Gain, shuffle, a configurable queue, podcasts, Internet radio and playlist import and export in XSPF, M3U and PLS formats. Plugins include integrations for MusicBrainz, CDDB, Last.fm, Sonos and Logitech Squeezebox; the feature page lists more than 80 contributed plugins. Podcast feeds are checked every two hours, and episodes can be downloaded. Radio streams support MP3 and Ogg Vorbis; other formats may need additional GStreamer plugins, and stations cannot be added to playlists or the play queue. Playback requires GStreamer or xine-lib. Quod Libet is free software under GNU GPL version 2 or later, though alternate terms may apply to some files or modules. The listed macOS 4.6.1 disk image is marked unofficial.

SMPlayer is a free media player for Windows, Linux, and macOS. It includes built-in codecs to play most audio and video formats without requiring external codecs. Listed formats include AVI, ASF/WMV/WMA, QT/MOV/MP4, RealAudio/RealVideo, Ogg/OGM, Matroska, MPEG-1/2, H.264, MPEG-4, MP3, AAC, AC3, and DTS. The player supports network playback, subtitles, hardware acceleration, and 4K playback. It provides a graphical interface for MPlayer and can also use mpv as its playback engine. SMPlayer remembers playback position and settings such as audio track, subtitles, and volume. Controls include playback speed adjustment, audio and video filters, audio and subtitle delay adjustment, and a video equalizer. It can play YouTube videos, search for subtitles through OpenSubtitles, and send local videos or online streams to Chromecast devices. The project is free and open source under the GPL, offers source code, and directs users to a forum for help and a bug tracker for reporting problems.
