MPlayer Subtitle (MPSUB) is a text-based subtitle format created by the MPlayer multimedia player. This format is used to convert and display subtitles in sync with movie files, storing subtitle information in a plain text format that is compatible with MPlayer.
History
MPlayer Subtitle (MPSUB) is a subtitle format developed for the MPlayer media player, an open-source multimedia player first released in 2000. The subtitle format was created in 2001 by MPlayer developers to offer a simple and effective way to integrate subtitles with the player. While MPlayer and its subtitle format were widely used in the early 2000s, both have largely become legacy software, with newer, more advanced players and subtitle formats taking their place.
