This is a networking library for use with SDL.

This is a sample library that allows you to use TrueType fonts in your
SDL applications.

This is a simple library to load images of various formats as SDL
surfaces. This library supports the BMP, PPM, PCX, GIF, JPEG, PNG,
TIFF and WEBP formats.

Speex is an Open Source/Free Software patent-free audio compression format designed for speech. The Speex Project aims to lower the barrier of entry for voice applications by providing a free alternative to expensive proprietary speech codecs. Moreover, Speex is well-adapted to Internet applications and provides useful features that are not present in most other codecs. Finally, Speex is part of the GNU Project and is available under the revised BSD license.

Speex is a patent free audio codec designed especially for voice
(unlike Vorbis which targets general audio) signals and providing good
narrowband and wideband quality. This project aims to be complementary
to the Vorbis codec.

WavPack is an open-source lossless audio codec.

The xz command is a very powerful program for compressing files.

* Average compression ratio of LZMA is about 30% better than that of
gzip, and 15% better than that of bzip2.

* Decompression speed is only little slower than that of gzip, being
two to five times faster than bzip2.

* In fast mode, compresses faster than bzip2 with a comparable
compression ratio.

* Achieving the best compression ratios takes four to even twelve
times longer than with bzip2. However. this doesn't affect
decompressing speed.

* Very similar command line interface to what gzip and bzip2 have.

A YAML parser and emitter in C++ matching the YAML 1.2 spec.

Zstd, short for Zstandard, is a lossless compression algorithm. Speed
vs. compression trade-off is configurable in small increments.
Decompression speed is preserved and remains roughly the same at all
settings, a property shared by most LZ compression algorithms, such
as zlib or lzma.

At roughly the same ratio, zstd (v1.4.0) achieves ~870%% faster
compression than gzip. For roughly the same time, zstd achives a
~12%% better ratio than gzip. LZMA outperforms zstd by ~10%% faster
compression for same ratio, or ~1–4%% size reduction for same time.

QToolButton with color popup menu with lets you select a color. The popup
featues a color dialog button which can be used to add custom colors to the
popup menu.

Ksnip is a Qt based cross-platform screenshot tool that provides many
annotation features for your screenshots.

cool-retro-term is a terminal emulator which tries to mimic the look and feel
of the old cathode tube screens. It has been designed to be eye-candy,
customizable, and reasonably lightweight.

This project is a QML port of qtermwidget.
