What is a OGV file?
Open-source video format for web HTML5 playback
OGV files are video files that use the Xiph.Org's open source Ogg container format; may contain video streams that use one or more different codecs, such as Theora. OGV files are primarily used to play webpage video content (usually within video tags within the HTML5 spec). Xiph.Org have a DirectShow codec pack that enables software developers and content creators to include support for OGV files in both open-source and commercial applications. OGV files are a binary stream media container format that combines several codecs of texts, subtitles, audio and video data. OGV files are not called OGG Vorbis files; ‘Vorbis’ is reserved for OGG files which are audio-only files that use the ‘Vorbis’ compression algorithm.
