Structure of stream output

Stream output is the name of the feature of VLC that allows to output any stream read by VLC to a file or as a network stream instead of displaying it. Different kind of processing can be applied to the stream during this process (transcoding, re-scaling, filters, re-muxing...). Stream output includes different modules, each of them having different capabilities. You can chain modules to enhance the possibilities.

Here is the list of the modules currently available:

• standard allows to send the stream via an access output module: for example, UDP, file, HTTP, ... You will probably want to use this module at the end of your chains.

• transcode is used to transcode (decode and re-encode the stream using a different codec and/or bitrate) the audio and the video of the input stream. If the input or output access method doesn't allow pace control (network, capture devices), this done "on the fly", in real time. This can require quite a lot of CPU power, depending on the parameters set. Other streams, such as files and disks are transcoded as fast as the system allows it.

• duplicate allows you to create a second chain, where the stream will be handled in an independent way.

• display allows you to display the input stream, as VLC would normally do. Used with the duplicate module, this allows you to monitor the stream while processing it.

• rtp streams over RTP (one UDP port for each elementary stream). This module also allows RTSP support.

• es allows you to make separate Elementary Streams (ES) out of an input stream. This can be used to save audio and video streams to separate files, for instance.

Each of these modules may take options. Here is the syntax that you must use:

% vlc input_stream --sout "#module1{option1=parameter1{parameter-option1},option2=parameter2}:module2{option1=...,option2=...}:..."

NOTE: Some of the module options (option1 in the example) have to be set, others are optional. Option parameters (parameter-option1 in the example) are always optional. These option parameters are also often very advanced settings. If you don't understand their description, this certainly means that you don't need them.

You may also use the following syntax :

% vlc input_stream --sout-module1-option1=... --sout-module1-option2=... --sout-module2-option1=... --sout-module2-option2=... ...

For example, to transcode a stream and send it, use:

% vlc input_stream --sout '#transcode{options}:standard{options}' 

Description of the modules

standard (alias std)

This module saves the stream to a file or sends it over a network, after having muxed it.

The available options are:

access

This option allows to set the medium used to save or send the stream. This is a compulsory option. Available options are:

• file: saves the stream to a file.

Use the append option to append the stream to an existing file instead of replacing it.

• udp: streams to a UDP unicast or multicast address.

Item options are:

• • caching= to set the time VLC should buffer data before sending it;
  • ttl=<ttl> to set the ttl of the sent udp packets;
  • group=<amount of packets> to sent packets by burst instead of one by one;
  • late= to drop packets that arrive too late at this stage of the chain;
  • raw if you don't want to wait until the MTU is filled before sending the packet.

• http: streams over HTTP.

Item options are:

• • user=<user name> to enable HTTP basic authentication and set the user;
  • pwd=<password> to set the basic authentication password;
  • mime=<mime type> to set the mime type returned by the server.

• https: streams over HTTP, using a secured SSL connection.

Item options are the same as for http and:

• • cert=<path to certificate>to set the certificate to use;
  • key=<path to key> to set the private key file the server should use for the SSL connection;
  • ca=<path to certificate> to set the path to the root CA certificates to use for SSL;
  • crl=<path to certificate> to set the revocation certificate to use for the SSL connection.

• mmsh: streams using the Microsoft MMS protocol. This protocol is used as transport method by many Microsoft's softwares.

Note that only a small part of the MMS protocol is supported (MMS encapsulated in HTTP). Item options are the same as for the http module.

• rtp: streams over RTP. Please note that this is a legacy module. It doesn't allow RTSP and can only be used to stream TS streams. Please have a look at the rtp stream output module for a more compliant and complete RTP streamer.

Options are the same as for the udp setting.

</itemizedlist> </sect3> <sect3><title>mux=</title>

This option allows you to set the encapsulation method used for the resulting stream. This option has to be set. Available options are:

<itemizedlist>

<listitem>ts: the MPEG2/TS muxer. This the

standard muxer used to stream MPEG 2. This muxer can be used with any access method. Supported codecs are MPEG 1/2/4, MJPEG, H263, H264, I263, WMV 1/2 and theora for video, MPEG audio, AAC and

a52 for the audio stream. Item options are: pid-video=<pid>

encryption.</listitem> <listitem>ps: the MPEG2/PS muxer. This the standard muxer for MPEG

2 files(.mpg). It can be used with the file and http output methods. Supported codecs are MPEG 1/2 and MJPEG for video, MPEG audio and a52 for

audio streams. The only available item option is dst-delay=<delay

in ms>. It allows to delay PTS (Presentation Time Stamps) from the DTS (Decoding Time Stamp) from the given

time.</listitem> <listitem>mpeg1: the standard MPEG 1 muxer. This muxer should be

used instead of ps with MPEG 1 video streams, when saved to a file or

streamed over HTTP. Supported codecs are MPEG 1 and MPEG audio. Items options are the same as for the PS muxer.</listitem> <listitem>ogg: the ogg muxer. This is the muxer from the Xiph

project. It can be used with the HTTP and file output methods. Supported codecs are MPEG 1/2/4, MJPEG WMV 1/2 and Theora, audio streams can be vorbis,

flac, speex, a52 or MPEG audio. There is no item option for this muxer.</listitem> <listitem>asf: the Microsoft ASF muxer. This is the standard muxer

encapsulation format for MPEG 4 files. The only supported output method is file. Supported codecs are MPEG 1/2/4, H263, H264 and I263 for video,

MPEG audio and a52 for audio streams. There is not item option for this muxer.</listitem> <listitem>mpjpeg: the multipart jpeg muxer.

This encapsulation format is mostly used on surveillance video cameras with an integrated web-server. Such streams are usually embedded in web-pages and seen with standard Internet browsers, as they are seen as a succession of jpeg images. The only supported output method is HTTP. The only usable codec is MJPEG. No sound track can be muxed

in such streams. No item option is available for this muxer.</listitem>

</itemizedlist> </sect3>

<sect3><title>dst=</title>

This option allows to give informations about the location where the stream should actually be saved or sent. Here is the meaning of the dst option

depending on the parameter used for the access

option.

output method is used, dst is the unicast or multicast destination address and, optionally, UDP port, in the form

address:port.</listitem> <listitem>If the http,

https or mmsh output method is chosen, dst is the address, port and path of the local network interface on which the server should listen for requests. If no address is given, VLC will listen on all the network interfaces. These information have to be supplied using the address:port/path

syntax.</listitem>

</sect3>

<sect3><title>select=</title>

This options can be used to duplicate only a part elementary streams of a complete stream. Several criteria can be given, by separating each of them with a comma. For criteria that need a parameter, such as

es and program, you can also specify a range, using the syntax

criteria=num_start-num_end. Available parameters are:

<itemizedlist>

<listitem>program=: duplicate only

elementary streams belonging to the selected program (or SID). This option only works with MPEG2/TS

streams.</listitem> <listitem>noprogram=: do not duplicate

elementary streams belonging to the selected program (or PID). This option only works with MPEG2/TS

streams.</listitem> <listitem>es=: duplicate only the

elementary stream with the selected

id.</listitem> <listitem>noes=: do not duplicate

the elementary stream with the selected

id.</listitem> <listitem>video: duplicate only video elementary streams.</listitem> <listitem>novideo: do not duplicate video elementary streams.</listitem> <listitem>audio: duplicate only audio elementary streams.</listitem> <listitem>noaudio: do not duplicate audio elementary streams.</listitem> <listitem>spu: duplicate only subtitle elementary streams.</listitem> <listitem>nospu: do not duplicate subtitle elementary streams.</listitem>

</itemizedlist>

Example:

#duplicate{dst=std{...},select="program=100-200,novideo"}

This duplicate chain will only output the non

video elementary streams belonging to the programs

which PID are between 100 and 200.

</sect3>

</sect2>

<sect2><title> Miscellaneous </title>

Here are a few additional global options:

<sect3><title>--sout-all, --no-sout-all</title>

Enable streaming of all ES (default disabled). By default VLC will

only stream one audio ES and one video ES (the first ones). If you

enable sout-all, all ES (audio, video and SPU) will be streamed.

</sect3>

<sect3><title>--sout-keep, --no-sout-keep</title>

Keep sout open (default disabled) : use the same sout instance across the various playlist items, if possible.

</sect3>

<sect3><title>--no-sout-audio</title>

This options allows to disable audio in the outputted stream.

</sect3>

<sect3><title>--no-sout-video</title>

This options allows to disable video in the outputted stream.

</sect3>

</sect2>

<sect2><title>Simplified Syntax</title>

The stream output also offers a simplified syntax, with which you can only you use the standard module main options:

<prompt>% </prompt><userinput>vlc input_stream --sout access/mux:url</userinput>

where access,

mux and url are as defined in the options of the standard module.
