AVI at a glance

AVI

AVI grew from Microsoft's RIFF multimedia architecture, which is why its structure reflects chunked stream handling and older desktop-video assumptions.

FLAC at a glance

FLAC

FLAC grew inside the Xiph open-media ecosystem and later gained a formal RFC description, which strengthened its standing as a stable open lossless format rather than a niche hobbyist codec.
