Mt : media table, store of in-memory display surfaces The following diagram shows the typical data flow and relevant commands between the main API objects:įt : frame table, maps of logical frames to the logical screen, corresponds to OpenGL textures

The source archive contains a custom mplayer version “MPlayer-1.0rc1-glstream” which should be compiled separately. The video compression format is based on a custom mplayer output mode “glstream”. – liblzf : fast compression, used by lbuffer The LUA scripting engine is provided and extended using these libraries which need to be compiled and installed: – SDL_vnc : simple multithreaded VNC client for SDL – SDL_bgrab : libbgrab interface for SDL, multithreaded v4l-based framegrabber interface The following locally provided custom libraries need to be also compiled and installed:

– liblzf : fast compression, used by lbuffer and custom mplayer – libbgrab : v4l interface, used by SDL_bgrab – freetype : TTF rendering, used by SDL_ttf – ffmpeg : video codecs, used by custom mplayer – SDL_ttf : font support and text drawing – SDL : simple direct media lib, core for graphics These should be installed as development packages prior to compiling smplayer2: The core mediaplayer depends on many secondary libraries common to a Linux distribution.

Since the player requires hardware accelerated OpenGL support, the proprietary drivers (i.e. last used version was Mandriva Linux 2008.1). The smplayer2 code is designed to compile and run on a 32bit Linux installation (i.e. – various utility functions written in LUA code – utility APIs (byte buffer, bit manupulation, compression, etc.) – smplayer2 specific objects and functions Smplayer2 extends it with the following APIs: Lua is a very compact, relatively fast and easily extensible functional programming language. Smplayer2 uses the LUA programming engine for screen and media setup and to control the display while the player is running. These make callbacks to scripts wich control visualizers. The program thread executes the media script and performs all “work” in controller- and visualizer-coroutines (not real threads).

The drawing algorithm allows for flatfield calibration (keystone). The graphics thread controls the drawing of OpenGL textures at a fixed rate to the physical screen.

The software implements a multithreaded scriptable “game loop”. Other than that, it is a very unique and capable piece of software that can help solve unique media display problems in a neat way. – Currently no (or very limited) audio support. – Scripts are not easy to program and debug lack of IDE. This is done using a custom mplayer binary and the files may consume a lot of disk space. – video must be converted into proprietary file format (stream of compressed textures) before playback. – many image sources (images, video clips, webcam, VNC) – contains many utility commands for controlling display script (i.e. – contains many commands for drawing graphics and text to screen – can handle several SD and HD streams concurrently – allows for flat-field calibrated synchronized playback on up to 2 screens It is based on a Linux PC with OpenGL graphics acceleration.

The smplayer2 software was created as a frontend driver for digital signage project and has since been used in some media-art installations.

The software is © Andreas Schiffler, aschiffler at, but released under a liberal OSS license. This is the source archive for smplayer a Linux+OpenGL based LUA scriptable mediaplayer that supports HD video playback and custom digital IO controls it was used as Digital Retina media art installation by Jill Scott in Version 2.0.
