Documentation:Streaming HowTo/Command Line Examples

Examples for advanced use of VLC's stream output (transcoding, multiple streaming, etc...)

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,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,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,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,sdp=sap,name="TestStream"},dst=rtp{mux=ts,dst=192.168.1.2}}' 

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},dst=rtp{mux=ts,dst=192.168.1.42}}' 

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},select="program=12345",dst=rtp{mux=ts,dst=239.255.12.43}, 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}}' 

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},dst=rtp{mux=ts,dst=192.168.1.12}"}' 

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,sdp=sap,name="OriginalStream"},dst="transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{mux=ts,dst=239.255.1.3,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}' 

Recording a live video stream:

% vlc http://example.com/live.asf --sout="#duplicate{dst=std{access=file,mux=asf,url='C:\test\test.asf'},dst=nodisplay}" 

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}' 

RTSP live streaming

Stream with RTSP and 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

RTSP on-demand streaming

See Documentation:Streaming HowTo/VLM.

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=192.168.1.2:1212,url_video=192.168.1.2:1213}' 

• on the client side:
  • to receive the audio:

% vlc udp://@:1212

• • to receive the video:

% vlc udp://@:1213

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.
