Transcoding

Transcode the input stream and send it to a multicast IP address with the associated SAP announce:

% vlc -vvv input_stream --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128,deinterlace}:
rtp{mux=ts,dst=239.255.12.42,port=5004,sdp=sap://,name="TestStream"}'

Display the input stream, transcode it and send it to a multicast IP address with the associated SAP announce:

% vlc -vvv input_stream --sout '#duplicate{dst=display,dst=
"transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128,deinterlace}:
rtp{mux=ts,dst=239.255.12.42,port=5004,sdp=sap://,name="TestStream"}"}'

Transcode the input stream, display the transcoded stream and send it to a multicast IP address with the associated SAP announce:

% vlc -vvv input_stream --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128,deinterlace}:
duplicate{dst=display,dst=rtp{mux=ts,dst=239.255.12.42,port=5004,sdp=sap://,name="TestStream"}}'

Multiple streaming

Send a stream to a multicast IP address and a unicast IP address:

% vlc -vvv input_stream --sout '#duplicate{dst=
rtp{mux=ts,dst=239.255.12.42,port=5004,sdp=sap://,name="TestStream"},
dst=rtp{mux=ts,dst=192.168.1.2,port=50000}}'

Display the stream and send it to two unicast IP addresses:

% vlc -vvv input_stream
--sout '#duplicate{dst=display,
dst=rtp{mux=ts,dst=192.168.1.12,port=50002},
dst=rtp{mux=ts,dst=192.168.1.42,port=50004}}'

Send parts of a multiple program input stream:

% vlc -vvv multiple_program_input_stream 
--sout '#duplicate{dst=rtp{mux=ts,dst=239.255.12.42,port=5004},select="program=12345",
dst=rtp{mux=ts,dst=239.255.12.43,port=5004}, select="video,program=1234-2345"}'

This command sends the program of the input stream which id is 12345 to 239.255.12.42 and all video programs with id between 1234 and 2345 to 239.255.12.43.

Transcoding and multiple streaming

Transcode the input stream, display the transcoded stream and send it to a multicast IP address with the associated SAP announce and an unicast IP address:

% vlc -vvv input_stream --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128,deinterlace}:
duplicate{dst=display,dst=rtp{mux=ts,dst=239.255.12.42,sdp=sap://,name="TestStream"},
dst=rtp{mux=ts,dst=192.168.1.2,port=50006}}'

Display the input stream, transcode it and send it to two unicast IP addresses:

% vlc -vvv input_stream --sout '#duplicate{dst=display,
dst="transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:
duplicate{dst=rtp{mux=ts,dst=192.168.1.2,port=50008},
dst=rtp{mux=ts,dst=192.168.1.12,port=50010}"}'

Send the input stream to a multicast IP address and the transcoded stream to another multicast IP address with the associated SAP announces:

% vlc -vvv input_stream --sout '#duplicate{dst=
rtp{mux=ts,dst=239.255.1.2,port=5004,sdp=sap://,name="OriginalStream"},
dst="transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:
rtp{mux=ts,dst=239.255.1.3,port=5004,sdp=sap://,name="TranscodedStream"}"}'

HTTP streaming

Stream in HTTP:

  • on the server, run:

    % vlc -vvv input_stream --sout '#standard{access=http,mux=ogg,dst=server.example.org:8080}'
    
  • on the client(s), run:

    % vlc http://server.example.org:8080
    

Transcode and stream in HTTP:

% vlc -vvv input_stream --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:
standard{access=http,mux=ogg,dst=server.example.org:8080}'

For example, if you want to stream an audio CD in Ogg/Vorbis over HTTP:

% vlc -vvv cdda:///dev/cdrom --sout '#transcode{acodec=vorb,ab=128}:
standard{access=http,mux=ogg,dst=server.example.org:8080}'

RTP streaming

Stream in RTP:

  • on the server, run:

    % vlc -vvv input_stream --sout '#rtp{dst=192.168.0.12,port=1234,sdp=rtsp://server.example.org:8080/test.sdp}'
    
  • on the client(s), run:

    % vlc rtsp://server.example.org:8080/test.sdp
    

Note

You can remplace the rtsp URL by a http one, a file path (prefixed with file://) or sap:// to export the sdp file using one of these methods instead of rtsp.

RTSP

See VLM - Multiple streaming and Video on demand

MMS / MMSH streaming to Windows Media Player

% vlc -vvv input_stream --sout '#transcode{vcodec=DIV3,vb=256,scale=1,acodec=mp3,ab=32,channels=2}:std{access=mmsh,mux=asfh,dst=:8080}'

VLC media player can connect to this by using the following url : mmsh://server_ip_address:8080 .

Windows Media Player can connect to this by using the following url : mms://server_ip_address:8080 .

Use the es module

Separate audio and video in two PS files:

% vlc -vvv input_stream --sout
'#es{access=file,mux=ps,url_audio=audio-%c.%m,url_video=video-%c.%m}'

Extract the audio track of the input stream to a TS file:

% vlc -vvv input_stream --sout '#es{access_audio=file,mux_audio=ts,url_audio=audio-%c.%m}'

Stream in unicast the audio track on a port and the video track on another port (NOTE: This will not only work with VLC 0.8.6 or older - FIXME?)

  • on the server side:

    % vlc -vvv input_stream --sout
    '#es{access=rtp,mux=ts,url_audio=192.168.1.2:50002,url_video=192.168.1.2:50004}'
    
  • on the client side: to receive the audio:

    % vlc rtp://@:50002
    

    to receive the video:

    % vlc rtp://@:50004
    

Stream in multicast the video and dump the audio in a file:

% vlc -vvv input_stream --sout '#es{access-video=udp,mux-video=ts,dst-video=239.255.12.42,
access-audio=file,mux-audio=ps,dst-audio=audio-%c.%m}'

Note

You can also combine the es module with the other modules to set-up even more complex solution.
