raw if you don't want to wait until the MTU is filled before sending the packet.

late= to drop packets that arrive too late at this stage of the chain.

group= to sent packets by burst instead of one by one.

ttl= to set the TTL of the sent UDP packets.

caching= to set the time VLC should buffer data before sending it.

udp: streams to a UDP unicast or multicast address.

Use the append option to append the stream to an existing file instead of replacing it : This option allows to set the medium used to save or send the stream. This module saves the stream to a file or sends it over a network, after having muxed it. In the following documentation, single bullet points represent options and double bullet points represent item options (sub-options) :ĭescription of the modules standard (alias std) This can be used to save audio and video streams to separate files, for instance.Įach of these modules may take options.

es allows you to make separate Elementary Streams (ES) out of an input stream.

rtp streams over RTP (one UDP port for each elementary stream).

Used with the duplicate module, this allows you to monitor the stream while processing it.

display allows you to display the input stream, as VLC would normally do.

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

Other streams, such as files and disks, are transcoded as fast as the system allows it. This can require quite a lot of CPU power, depending on the parameters set. If the input or output access method doesn't allow pace control (network, capture devices), this will be done ' on the fly', in real time.

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.

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.

Here is the list of the modules currently available :

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