Beyond the continued flow of new performance optimizations via hand-written Assembly, with the FFmpeg project it’s also interesting to monitor their ever-expanding scope of supported audio/video formats. The newest to land in FFmpeg Git is support for AHX audio files.
AHX is short for the Abyss’ Highest eXperience. AHX is from the late 90’s and is used for creating Amiga Commodore 64 like synthetic tunes. AHX support on Linux has been available via an XMMS plug-in and similar while now can also be decoded by the versatile FFmpeg multimedia library.
Along with adding the AHX support, the slew of patches merged to FFmpeg Git overnight also include adding a ADPCM Silicon Graphics N64 decoder for the Nintendo 64 as well as a number of other formats.
