Overview

FLV is closely associated with Adobe Flash video ecosystem.
FLV is usually selected for workflows that center on editing, mastering, streaming delivery.

Interesting Context
FLV is inseparable from the Flash era of online media, when browser plugins rather than native video elements dominated streaming video experiences.
FLV belongs to the Adobe Flash publishing era, streaming servers, early online video platforms, and archived courseware or media libraries that were built for browser plugins.
Modern transcoders and players still support it because so much historical content exists in FLV, but active web delivery has moved elsewhere.
Its ecosystem is now defined by migration, extraction, and preservation.
