DVD Video Movie File magic bytes (.vob)
.vob file signature: 00 00 01 BA | application/octet-stream
Category: Video
DVD Video Object (VOB) is a container format defined for the DVD-Video standard and maintained by the DVD Forum. It is used to store video, audio, subtitles, and navigation data for DVD movie titles, menus, and bonus content. VOB files are a legacy format associated with optical disc playback; they are generally safe, though some implementations may include complex multiplexed streams that can challenge older software.
