Receive a stream with VLC

Receive an unicast stream
     vlc -vvv rtp://

Receive a multicast stream
     vlc -vvv rtp://@239.255.12.42

Receive an HTTP/FTP/MMS stream
     vlc -vvv
     vlc -vvv ftp://example/stream.xyz
    vlc -vvv mms://viptvr.yacast.fr/encoderfranceinfo

Receive a RTP stream available through RTSP
     vlc -vvv rtsp://

Receive a stream described by an SDP file
     vlc -vvv

Save a stream with VLC
    --sout file/muxer:stream.xyz
where:
    muxer is one of the formats supported by VLC's stream output, i.e. :
        ogg for OGG format,
        ps MPEG2-PS format,
        ts for MPEG2-TS format.
    and stream.xyz is the name of the file you want to save the stream to, with the right extension.

For example:
    vlc your_input_file_or_stream_here --sout=file/ps:go.mpg
    This is short hand for the more verbose
    vlc your_input_file_or_stream_here --sout="#std{access=file,mux=ps,dst=go.mpg}"

以上都是命令行接收方式，图形界面的网上很多介绍，用到的命令类似。
