Codec is short for coder/decoder.
For [http://discerning.com/topics/audiovideo/video_encoding.html portability to almost all decoders], we recommend
using the [[MPEG-1]] standard of vcodec=mp1v, acodec=mpga, and mux=mpeg1. See the [[MPEG]] Wiki page for more details on the other MPEG standards.

To save a file in a different codec, you can use the transcoding [[wizard]] or [[transcode]] from the [[command prompt]] with a command like this:
:vlc file --sout='#transcode{vcodec=''mp1v'', vb=''1024'', acodec=''mpga'', ab=''128''}:std{access=file, mux=''mpeg1'', url=''C:\file_name.mpg''}'

MPEG

2006-12-09T09:37:02Z

Olawlor: Added examples for MPEG-1 and MPEG-4 video, and added a link to the Codec page.

{{wikipedia|MPEG}}
MPEG refers to a set of standards created by the [http://www.chiariglione.org/mpeg/ Moving Picture Experts Group]. MPEG refers to several video, audio and [[container]] formats; see the full list at the [[Codec]] page.

An MPEG file is a file using an MPEG container (these are called ''mpeg1'', ''ts'', ''ps'', and ''mp4'' for MPEG-4).

== Creating an MPEG File with VLC ==
To make an MPEG file, you need to:
* Pick a container (see [[#Muxers|below]])
* Transcode the audio and video to formats able to be held in the container: in general this is the MPEG video and audio formats only. Check the [http://www.videolan.org/streaming/features.html compatibility information] in the official documentation, but be warned that while vlc allows any codec and mux, most other players support only a few combinations!

== MPEG-1 and 2 ==
{{wikipedia|MPEG-1}}
{{wikipedia|MPEG-2}}

* Video codec: '''mp1v''', '''mp2v'''
* Audio codec: '''mpga''', '''mp2a''', '''mp3'''
* Muxer: '''ts''', '''ps''', '''mpeg1'''

MPEG-1 is a video and audio compression format, used in [[Video CD]]s. It is compatible with a large number of software and hardware devices.

Here is an example of how to transcode an AVI into a portable MPEG-1 video from the [[command prompt]]
<blockquote>
vlc ''file.avi'' --sout='#transcode{vcodec=mp1v, acodec=mpga}:std{access=file, mux=mpeg1,url=''file.mpg''}'
</blockquote>

MPEG-2 is used in digital television and [[DVB]]. It is also used as the format for [[DVD]]s. The biggest advantage of this format over MPEG-1 is in its support for interlaced pictures; MPEG-2 can cleanly compress interlaced video, while MPEG-1 internally only works on progressive-scan video, so interlacing must be faked.

Here is an example of how to transcode an AVI into an MPEG-2 video from the [[command prompt]]
<blockquote>
vlc ''file.avi'' --sout='#transcode{vcodec=mp2v, acodec=mpga}:std{access=file, mux=ps,url=''file.mpg''}'
</blockquote>

=== MPEG-1 Audio ===
MPEG-1 also contains several audio compression formats:
* '''mpga''' is MP1 or MPEG-1 (Part 3) Layer 1
* '''mp2a''' is MP2 or MPEG-1 (Part 3) Layer 2
* '''mp3''' is [[MP3]] or MPEG-1 (Part 3) Layer 3

=== Muxers ===
MPEG-2 specified 2 [[container]] formats, ts and ps. Containers hold video and audio information in them, and package them up so it can be sent over a network or stored on disk.
* '''ts''' (Transport Stream) should be used to store or send data where data loss will probably occur, such as over a network.
* '''ps''' (Program Stream) should be used to store or send data where data loss is not likely, such as on a DVD.

Both ps and ts can transport MPEG-4 Video, but only ts can send MPEG-4 Audio. In addition, MPEG-4 specifies it's own muxer, '''mp4''' (see [[#MPEG-4|below]])

== MPEG-3 ==
{{wikipedia|MPEG-3}}
A largely unused audio and video compression format.
* Note that the amazingly common [[MP3]] audio files are actually '''MPEG-1 Layer 3''' audio, not MPEG-3.

== MPEG-4 ==
{{wikipedia|MPEG-4}}
* Video codec: '''mp4v''' ('''m4v''')
* Audio codec: '''mp4a''' ('''m4a''') - this is [[AAC]].
* Muxer: '''mp4'''
MPEG-4 is a flexible audio and video compression format. The format describes audio and video compression, with a container format for streaming across networks and saving to disk. It also contains optional extra features, including [[DRM]] and [[subtitles]]. These extra features are only included in software if needed. MPEG-4 can provide better quality than MPEG-2 at low bitrates.

Here is an example of how to transcode an AVI into an MPEG-4 video from the [[command prompt]]
<blockquote>
vlc ''file.avi'' --sout='#transcode{vcodec=mp4v, acodec=mpga}:std{access=file, mux=mp4,url=''file.m4v''}'
</blockquote>

Olawlor: Added a link to the cool MPEG-4 wiki page, and gave a better pointer to the mp4 mux.

''See Also the [http://www.videolan.org/doc/vlc-user-guide/en/ch02.html Official documentation: list of modules]''

''For more information of codecs in general, look at [[wikipedia:Codecs|Wikipedia]] and [http://wiki.multimedia.cx wiki.multimedia.cx].''

Codec is short for coder/decoder.
For portability to almost all decoders, we recommend
using the [[MPEG-1]] standard of vcodec=mp1v, acodec=mpga, and mux=mpeg1. See the [[MPEG]] Wikipedia page for more details on the other MPEG standards.

To save a file in a different codec, you can use the transcoding [[wizard]] or [[transcode]] from the [[command prompt]] with a command like this:
:vlc file --sout='#transcode{vcodec=''mp1v'', vb=''1024'', acodec=''mpga'', ab=''128''}:std{access=file, mux=''mpeg1'', url=''C:\file_name.mpg''}'

Olawlor: Delete porno spam links; add example of how to call vlc.

[[wikipedia:Codec|Codec]] is short for coder/decoder.
For portability to almost all decoders, we recommend
using vcodec=mp1v (MPEG 1 video), acodec=mpga (MPEG 1
layer 1 audio), and mux=mpeg1 (MPEG 1 multiplexing).

The minimal command to transcode from a capture card to
a portable MPEG file is thus:
vlc v4l:// :v4l-norm=1: '--sout=#transcode{vcodec=mp1v,vb=2030,audio-sync,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=file,mux=mpeg1,url="out_file.mpg"}}'

These MPEG files have been verified to work with:

* Windows Media Player 10
* Apple QuickTime Player 7
* XINE 1.0
* ffplay
* xanim 2.80 (no audio)

MP4 audio

Olawlor:

MPEG-4 audio is an advanced, complicated audio format. It includes AAC for high bitrates, multilingual tracks, text-to-speech modes for very low bitrates, the ability to synthesize instrumental sounds (similar to MIDI), and more. See the [http://www.tnt.uni-hannover.de/project/mpeg/audio/faq/mpeg4.html MPEG-4 Audio FAQ] for details. In vlc, you enable MPEG-4 audio with 'acodec=mp4a'.

MPEG audio

Olawlor:

MPEG 1 layer 1 and layer 2 audio are more primitive, but more portable versions of the incredibly popular "MP3" (MPEG 1 Layer 3) audio format.
See the [http://www.tnt.uni-hannover.de/project/mpeg/audio/faq/mpeg1.html MPEG 1 Audio FAQ] for details. These are selected in vlc with "acodec=mpga" (for Layer 1) and "acodec=mp2a" (for Layer 2). Also see [[MP3 Audio]] page.
