I've exactly the same problem and the same question.

I can stream my webcam from my computer (vista64) but i'd like to stream it automaticaly each time windows start up. And i'd like that to be like a hidden service, without having on the screen any sign of vlc.

I've tried several things without success.

Do you have an idea to help me?

Thanks a lot

You can copy the parameters from GUI. So something like

Thanks for your answer Where do i need to copy these lines? Is there something to write there to tell vlc to stream in background and not show any interface?

hello

thanks for your answer. one more thing i wanted was that i am using the vlc plugin in c# application. i have copied the parameters from the gui. however i dont know where to set the ttl parameter. in the gui if we set the ttl paremeter we cannot copy it like the rest of them. how to set the ttl paremter from outside.

Use dummy interface. -I dummy

however i dont know where to set the ttl parameter

--sout-rtp-ttl=<integer> Hop limit (TTL)
This is the hop limit (also known as "Time-To-Live" or TTL) of the
multicast packets sent by the stream output (0 = use operating system
built-in default).

in case you rtp.

hello

thanx a lot for the reply. i placed the ttl as mentioned by you in my code below. i have set the value to maximum coz the steream has to pass through multiple routers.howerver i am not able to view the stream at the client end. if i set the same parameters from the wizard then i am able to view the stream at other end. i think i am not setting the ttl parameter at a proper place. plase help me with this.

Dim vlc_opt As String() = New String() {":dshow-vdev=Acer crystel eye webcam" , ":dshow-adev=Realket audio input" , ":dshow-size=320x240", " :dshow-fps=30.000000", ":sout=#transcode{vcodec=h264,vb=256",scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=display,dst=std{access=udp,ttl=255,mux=ts,dst=239.255.12.14:1234}""}"}

I assume you are using 0.8.6 series. In that case you can try --ttl= so for example
":ttl=255 :dshow-vdev=Acer crystel eye webcam" , ":dshow-adev=Realket audio input" , ":dshow-size=320x240", " :dshow-fps=30.000000", ":sout=#transcode{vcodec=h264,vb=256",scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=display,dst=std{access=udp,mux=ts,dst=239.255.12.14:1234}""}"
