## Historique du projet et usages

libmpeg2 is a free GPL C library for decoding MPEG-1 and MPEG-2 video streams, distributed with the mpeg2dec test program. It represents the small, focused multimedia libraries that predate the dominance of larger codec frameworks.

### Historique du projet

The official download page lists mpeg2dec 0.1.7 on November 2, 2000 with MPEG-1 and MPEG-2 support, an integrated demuxer, and standards-compliance work. Later releases added a new libmpeg2 API, 4:2:2-profile decoding, robustness improvements, and platform optimizations.

The 2008 libmpeg2 0.5.x releases brought newer compiler and system support, SSE2 and ARM optimizations, aspect-ratio handling, and installation/pkg-config fixes. The official project page also notes VideoLAN maintainers joining the project.

### Historique d'adoption

libmpeg2 became a reusable decoder dependency because it was portable C code with a narrow library purpose and a bundled test program. The batch input lists broad package-manager coverage across Homebrew, Debian-family, Fedora-family, Arch, MacPorts, Nix, and openSUSE ecosystems.

Upstream lists projects using libmpeg2, including xine, VideoLAN, MPlayer, GStreamer, XBMC, HandBrake, and other media tools, showing its historical role as a shared MPEG decoder component.

### Modes d'utilisation

Downstream software uses libmpeg2 to decode MPEG-1 and MPEG-2 streams. Packagers and developers can use mpeg2dec as a simple test program and rely on the official conformance test-suite notes on the download page.

### Pourquoi les passionnés de paquets s'y intéressent

For package maintainers, libmpeg2 is notable as a compact codec library with hand-written CPU optimizations, GPL licensing, pkg-config metadata, and a long tail of reverse dependencies. It persists because legacy media formats and decoder dependencies remain relevant long after newer codecs appear.

### Chronologie

- 2000-11-02: mpeg2dec 0.1.7 release with MPEG-1 and MPEG-2 support.
- 2002-11-27: mpeg2dec 0.3.0 release with a new libmpeg2 API.
- 2003-12-23: mpeg2dec 0.4.0 release with 4:2:2-profile decoding and robustness work.
- 2006-09-19: mpeg2dec 0.4.1 portability and bugfix release.
- 2008-07-12: libmpeg2 0.5.0 release with SSE2 and ARM optimizations.
- 2008-07-19: libmpeg2 0.5.1 release fixing header installation and pkg-config files.
