OGV is the Ogg container with video tracks inside — usually Theora, sometimes VP8 or Dirac. Theora itself descended from VP3, a codec On2 Technologies open-sourced in 2001; Xiph.Org maintained it into Theora 1.0 (2008). The .ogv extension was formalized around 2007 to give video-bearing Ogg files a clearly different extension from audio-only .ogg or .oga.

OGV’s moment came in the late 2000s when the HTML5 <video> tag was still figuring out which codec to bundle by default. Firefox, Opera, and Chrome added Theora playback; Safari and IE refused on licensing grounds. Wikipedia mandated OGV for all video uploads in 2010. Then WebM (VP8, 2010; VP9, 2013) arrived with better compression and the open-codec baton passed. Today OGV is mostly a Wikipedia and museum-grade-archive format.

CIEKAWOSTKI I
FAKTY.

Wikipedia requires all uploaded video to be in OGV or WebM — you cannot upload an MP4.

Theora inside OGV descends from VP3, an On2 codec open-sourced in 2001 — years before On2 was bought by Google and created VP8/VP9.

Between 2008 and 2012, HTML5's default "open" video was OGV — until WebM overtook it.

A single Ogg container can multiplex Theora video, Vorbis audio, and Kate subtitles all in one .ogv file.

Theora's compression efficiency lagged H.264 by a generation, which is why WebM/VP9 overtook it among open codecs.

ZALETY I
OGRANICZENIA.

Zalety

Patent-free codec (Theora) and container (Ogg).
Mandatory for Wikipedia uploads — preserves public-domain video.
Good for small educational clips.
Open-source reference implementations.

Ograniczenia

Compression lags H.264 by ~40% at equal quality.
Hardware decoders never adopted Theora.
WebM (VP9/AV1) is the modern open-codec choice.
iOS and Safari never supported Theora natively.
