Module: gather
Type Stream output
First VLC version -
Last VLC version -
Operating system(s) all
Description Recycle video and audio elementary streams when possible
Shortcut(s) -

Makes it possible to stream a playlist without any noticeable interruption on input change on the client side.
The audio and video streams must all have the same characteristics (codecs, bit rate, dimensions, etc.).

Example

% vlc playlist.m3u --sout "#gather:std{access=http,mux=asfh,dst=:8080}" --sout-keep

If your playlist items use different codecs or have different sizes, it is advised to transcode. For example:

% vlc playlist.m3u --sout "#transcode{vcodec=DIV3,vb=512,width=640,height=480,acodec=mp3,ab=128,samplerate=44100,channels=2}:gather:std{access=http,mux=asfh,dst=:8080}" --sout-keep

It is unclear whether using --sout-keep automatically sets gather automatically or not http://forum.videolan.org/viewtopic.php?f=14&t=80695
