.OGV File Extension
What is an OGV file?
An OGV file is a video file saved in the Xiph.Org open-source Ogg container format. It contains video streams encoded with one or more codecs, such as Theora, Dirac, or Daala, and may or may not store audio streams. Users often utilize OGV files to save video content for publishing on webpages.
The Ogg container format is a multimedia format that supports multiple video, audio, text, and metadata streams. You can compress each stream in the container with different compression methods. For example, the video stream in an Ogg container may be compressed with Theora compression, and the audio stream may be compressed with Vorbis compression.
The Xiph.Org Foundation, which develops Ogg, recommends that Ogg container files that only store audio data use the .ogg or .oga file extension (.OGG and .OGA files). Also, Xiph.Org recommends that Ogg container files that store video data use the .ogv extension (OGV files).
Common usage for OGV files
Web developers and content creators often utilize OGV files for sharing video content using the HTML5 <video> tag. However, they are generally referenced in the HTML source code with the .ogg extension, even though the files contain video content.
NOTE: Audio files that use the Ogg container are called Ogg Vorbis files, where "Vorbis" refers to the specific compression algorithm used for the audio data. The term "Vorbis" does not apply to Ogg video content.
How to open an OGV file
NOTE: Xiph.Org, the developers of the OGV format, provide a DirectShow codec pack that enables software developers to include support for OGV files in both open-source and commercial applications.
