OGV uses Xiph.org's Theora video codec in the Ogg container — a fully open, patent-free video format. FLV (Flash Video) was Adobe's proprietary streaming format, dominant on the web from 2005-2015 through YouTube, Vimeo, and millions of Flash-embedded websites. FLV supports H.264 or VP6 video with AAC, MP3, or Speex audio.
Despite Flash Player's end-of-life in December 2020, FLV remains required by legacy RTMP streaming servers, older content management systems, and Flash-based educational platforms that have not migrated to HTML5. Converting OGV to FLV enables open-source video content to be ingested by these legacy systems.
Some video archival workflows also require FLV as a delivery format for historical consistency when maintaining content libraries that span the Flash era.
FFmpeg decodes OGV's Theora video and Vorbis audio, then re-encodes to H.264 Baseline or Main Profile with AAC audio for FLV compatibility. VP6 encoding is also available for maximum Flash Player backward compatibility. Audio can be MP3 or AAC. The FLV container uses a tag-based structure where each packet is marked with a timestamp and stream type.
H.264 in FLV produces significantly better quality than Theora at the same bitrate. The converted FLV typically looks better than the OGV source at a similar or smaller file size. VP6 encoding is less efficient but ensures compatibility with the oldest Flash Player versions (6-8).
