On a video DVD(Digital Video Disc or Digital Versatitle Disc), you can see various types of files which contain Audio, Video, Subtitle, Chapters, Menu and many others system file information which are required to play a DVD. Video Object, aka VOB is the file than contains the audio and video materials of any DVD. Normally files in VOB format may be encrpted. To want to play VOB files on more devices, many guys long for converting VOB to a wider used video format – MP4 for streaming on more deivces.
Why to Convert VOB to MP4?
Reason one: Files in VOB format have a .vob filename extension and are typically stored in the VIDEO_TS directory at the root of a DVD. The VOB format based on the MPEG program stream format, but with additional limitations and specifications in the private streams. The MPEG program stream has provisions for non-standard data (as used in VOB files) in the form of so-called private streams. VOB files are a very strict subset of the MPEG program stream standard. While all VOB files are MPEG program streams, not all MPEG program streams comply with the definition for a VOB file.
Reason two: Almost all commercially produced DVD-Video titles use some restriction or copy protection method, which also affects VOB files. Many DVD-Video titles are encrypted with Content Scramble System (CSS). Decryption and authentication keys needed for playing back encrypted VOB files are stored in the normally inaccessible lead-in area of the DVD and are used only by CSS decryption software. In some countries, their usage can be a violation of law (e.g. for non-personal use).
