Penguin Subtitle Player GitHub release Build Status SourceForge Github All Releases penguin-subtitle-player

Penguin Subtitle Player is an open-source, cross-platform standalone subtitle player, as an alternative to Greenfish Subtitle Player, SrtViewer (Mac), SRTPlayer, JustSubsPlayer and Free Subtitle Player.

You download the subtitle file (.srt, .ssa, .ass, .vtt) from any sites you like and load it into the subtitle player. The subtitle player provides a translucent window which always stays on the top so that subtitles can be shown on top of the video without blocking anything.

With Penguin Subtitle Player, just open your favorite online streaming site, load the subtitle file into the player, and enjoy.

Check here for deployment details.


The easy way

  1. Download Qt with Qt Creator here
  2. Open the .pro file in Qt Creator
  3. You should be good to go (In case of some weird compilation errors, turn off the shadow build option in projects build settings)

The hard way

  1. Download Qt (Qt Creator is not required) here
  2. Run qmake
  1. Build from the makefile generated by qmake
  • G++ (Linux, Mac OSX): make
  • VC++ (Windows): nmake
  • MinGW (Windows): mingw32-make
  1. You should see the executable under build/debug or build/release

In case you would like to deploy a version which does not require Qt libraries in the client's system, consider statically build Qt then qmake with the static option, or change the config line in to

CONFIG += static \


  1. Run qmake "CONFIG+=test"
  2. Build from the makefile as described in the Building part
  3. Run the executable

Note: This project is using TravisCI for testing.


  1. Fork it!
  2. Create your feature branch: git checkout -b my-new-feature
  3. Commit your changes: git commit -am 'Add some feature'
  4. Push to the branch: git push origin my-new-feature
  5. Submit a pull request :D
