aperçu
Library for decoding ATSC A/52 streams (AKA 'AC-3')
historique
a52dec is the command-line test decoder and distribution package for liba52, a C library for decoding ATSC A/52 audio streams, also known as AC-3.
The project started publicly as ac3dec in 1999 and evolved into a52dec/liba52 in 2001. The official ChangeLog records the first public ac3dec release in June 1999, the 0.7.0 liba52-era release in August 2001, and the 0.7.4 release in July 2002.
The project then had a very long quiet period after the 2004 0.7.5 development snapshot. In 2022, Adelie Linux imported the historically available SourceForge code into Git, declared the Adelie GitLab URL canonical for source control and issue tracking, and took over maintenance while trying to minimize churn.
The README names xine, VideoLAN, MPlayer, FFmpeg, drip, and GStreamer as projects that used liba52, which explains why distributions kept shipping a small standalone a52dec package long after upstream development slowed.
The a52dec program decodes ATSC A/52 files and can demultiplex MPEG-1 and MPEG-2 program streams. Typical use is running a52dec against an AC-3/A52 file, with options for multiplexed streams, output layer selection, optimization control, and dynamic range compression.
a52dec is interesting to package maintainers because it is a classic codec-library package with a tiny CLI, old CVS-era history, GPL licensing, dormant upstream years, and a later distribution-led maintenance handoff.
