Chapter 3. Advanced streaming using the command line

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=<time in ms> 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=<time in ms>

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 This can only be used to stream MPEG-TS over plain RTP. Support for this option has been

removed in VLC 0.9.0 and latter. You should use the rtp stream output module instead. Options are the same as for the

udp setting.

mux=

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

Available options are:

• 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> to set the PID of the video track, pid-audio=<pid> to set the PID of the audio track,

pid-spu=<pid> to set the PID of the subtitle track, pid-pmt=<pid> to set the PID of the PMT (Program Map Table),

tsid=<id> to set the ID of the resulting TS stream, shaping=<shaping delay in ms> to set the minimum interval during

which the bitrate of the stream will remain constant, for variable bitrate streams, use-key-frames uses I frames as limits

for the shaping intervals, pcr=<PCR interval in ms> allows to set at which interval Program Clock References will be

sent, dts-delay=<delay in ms> allows to delay PTS (Presentation Time Stamps) from the DTS (Decoding Time Stamp)

from the given time, crypt-audio allows to enable encryption of the audio track using the CSA algorithm, csa-ck=<key

as a 16 character word> allows to set the key used for CSA encryption.

• 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.
