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.

• 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.

• 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.

• asf: the Microsoft ASF muxer. This is the standard muxer used for streaming by Microsoft’s softwares. Is also used as

container for WMA audio ﬁles. This muxer can be used with the ﬁle and HTTP output methods. Supported codecs are

MPEG 4, MJPEG, WMV 1/2 for video, MPEG audio, a52 for audio streams.

Item options are: title=<title>, autor=<author>, copyright=<copyright message>, comment=<comments>,

rating=<rating> allow you to set what will be displayed in the according ﬁeld of the stream comments.

• asfh: this is a special version of the ASF muxer, that should be used for MMSH streaming. MMSH is the only supported

output method. Supported codecs are the same as for ASF.

Item options are the same as for ASF.

• avi: the Microsoft AVI muxer. This is very common 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.

• 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.

dst=

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.

• If the ﬁle output method is used, dst is the complete path where the ﬁle should be saved.

• If the udp or rtp output method is used, dst is the unicast or multicast destination address and, optionally, UDP port, in

the form address:port.

• 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.

sap

Use this option if you want VLC to send SAP (Session Announcement Protocol) announces. SAP is a service discovery

protocol, that uses a special multicast address to send a list of available streams on a server.

Note: This option can only be enabled with the udp output method.
