'''MPEG Elementary Stream''' (ES) refers to a family of compressed media formats defined by the [[MPEG-1]] and [[MPEG-2]] standards. An MPEG Elementary Stream can appear on its own as a file format, in which case the file can have only video or only audio. Or, it can be combined with other streams in a container format such as [[MPEG Program Stream]].

Most '''.mpg''' files use either MPEG Elementary Stream video format, or [[MPEG Program Stream]] format.

An [[MP3]] file is a type of MPEG Elementary Stream file, at least if it does not include [[ID3]] or similar metadata.

== Disambiguation ==
The term ''elementary stream'' can also refer generically to a single video or audio stream (whether one of the standard MPEG codecs or not), regardless of what layer it is at in the encoding process. So, it might be [[Packetized Elementary Stream|packetized]], and/or part of an [[MPEG Program Stream]].

== Identification ==
An MPEG video Elementary Stream begins with bytes {{magic|00 00 01 B3}}.

An MPEG audio Elementary Stream begins with {{magic|0xff 0xf?}}.
