Ogg Vorbis Codec compressed Multimedia file (.ogv)
.ogv file signature | video/ogg
Ogg Video (OGV) is an open multimedia container format based on the Ogg specification, developed and maintained by the Xiph.Org Foundation. It is commonly used to store video and audio streams for web playback, archiving, and open-format media distribution in browsers and media players. The format is generally safe to handle, although like other media files it should still be opened with up-to-date software to reduce codec-related vulnerabilities.
