On the operating systems on which SMPlayer has not yet been ported to, it is likely possible to run the application through binary compatibility with another Unix or Linux. This makes it quite portable, since MPlayer and Qt are already available on all major operating systems.

SMPlayer is built with Qt and is based on MPlayer. Packages Interface playing an audio file on Ubuntu 16.10 SMPlayer 0.6.7 on Windows Vista SMPlayer playing the movie Sintel on Ubuntu 12.04. Some of the features of SMPlayer are: holding a memory of the time position of each file it has played, audio/ video filters and equalizer, variable speed playback (it also allows for frame-by-frame playback, forwards or backwards), configurable subtitles with Internet fetch, YouTube & Radio & TV support with playback of up to 4K resolution at 60 fps, skinnable user interface, automatic support for EDL files, and Chromecast support (requires Google Chrome or Chromium and the 'webfs' package.) SMplayer has been localized in more than 30 languages. SMPlayer is free and open-source software subject to the terms of the GNU General Public License version 2 or later. SMPlayer is a cross-platform graphical front-end for MPlayer and mpv and forks of Mplayer using GUI widgets offered by Qt.
