9.2. Examples9.2.1. 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}:
standard{access=udp,mux=ts,url=239.255.12.42,sap=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}:
standard{access=udp,mux=ts,url=239.255.12.42,sap=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=standard{access=udp,mux=ts,url=239.255.12.42,sap=TestStream}}'
|
9.2.2. Multiple streaming
Send a stream to a multicast IP address and a
unicast IP address
:
% vlc -vvv input_stream --sout '#duplicate{dst=
standard{access=udp,mux=ts,url=239.255.12.42,sap=TestStream},
dst=standard{access=udp,mux=ts,url=192.168.1.2}}'
|
Display the stream and send it to two unicast IP
addresses
:
% vlc -vvv input_stream --sout '#duplicate{dst=display,dst=
standard{access=udp,mux=ts,url=192.168.1.12},
dst=standard{access=udp,mux=ts,url=192.168.1.42}}'
|
9.2.3. 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=standard{access=udp,mux=ts,url=239.255.12.42,sap=TestStream},
dst=standard{access=udp,mux=ts,url=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=standard{access=udp,mux=ts,url=192.168.1.2},
dst=standard{access=udp,mux=ts,url=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=
standard{access=udp,mux=ts,url=239.255.1.2,sap=OriginalStream},
dst="transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:
standard{access=udp,mux=ts,url=239.255.1.3,sap=TranscodedStream}"}'
|
9.2.4. HTTP streaming
Stream in HTTP
:
on the server, run
:
% vlc -vvv input_stream --sout '#standard{access=http,mux=ogg,url=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,url=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,url=server.example.org:8080}'
|
9.2.5. 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
:
Stream in multicast the video and dump the audio in
a file
:
% vlc -vvv input_stream --sout '#es{access_video=udp,mux_video=ts,url_video=239.255.12.42,
access_audio=file,mux_audio=ps,url_audio=audio-%c.%m}'
|
 |
You can also combine the es
module with the other modules to set-up even more complex
solution
