AA-lib is a low level gfx library just as many other libraries are. The main difference is that AA-lib does not require graphics device. In fact, there is no graphical output possible. AA-lib replaces those old-fashioned output methods with a powerful ASCII art renderer. The API is designed to be similar to other graphics libraries.
Audiality is a highly scalable and portable audio engine and synthesizer. MIDI files are used in combination with scripting and modular synthesis, to minimize file sizes and maximize flexibility. Audiality can be used as a music and sound effects player in multimedia productions, or as a realtime MIDI synthesizer.
BZFlag is a 3D, multiplayer, tank battle zone, capture the flag game that pits players against each other in a networked environment. It runs on Windows 95/98/NT/2000, Linux, MacOS 10.x, Irix, Solaris, and others. An OpenGL accelerator is highly recommended, but it is playable with 3D in software.
The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
FFmpeg is a tool for converting audio, video, and subtitles. It includes libavcodec, the leading open source codec library. It also includes libavformat (implementing muxers and demuxers), libswscale (for very fast video scaling), and libavfilter (an advanced video filter system supporting arbitrary filter graphs), and libavutil (a utility library intended to supplement libc). A simple multimedia player is included too. An experimental streaming server for live broadcasts is also included.
FXL Template an easy to use template engine offering all the basic features of a template system. It supports simple text/array assignments, blocks, and nested blocks. Well-used regular expressions and the simple template syntax are responsible for quick template processing. The template markup is quite easy to learn, even for those not into programming. A Memcache extension for high traffic pages is freely available.
LGI is a lightweight GUI library and application framework. It supports cross-platform widgets, threads, Unicode, a multi-language resource file in XML (with graphical editor), drag and drop, common dialogs, network support with implementations of common protocols, and an HTML control.
