Stream and Re-transmit Webcam

[wsjunior]

Hello guys,

Going direct to the point:

1 - I have a webcam plugged into a computer in my LAN and it doesn't have an external IP, so I would like to stream my webcam to anyone on Internet.
2 - I have access to another computer which has an external IP like 200.130.15.X and the port 1935 is open.
3 - I would like to start streaming from the computer in my LAN and send this stream to this computer with an external IP and make it re-transmit the stream to the internet, so anyone would access it throught http://200.130.15.X:1935

Question: How to do that?

I'm using Debian Squeeze and I would like some command line solutions/examples, could anybody help me with this?

I'm able to start stream locally in my LAN computer with this command:

vlc v4l:///dev/video0 --sout '#transcode{vcodec=theo,vb=256}:standard{access=http,mux=ogg,dst=:1935}'

And the if I open another instance of VLC and open http://127.0.0.1:1935 it works.

How do I send this same stream to 200.130.15.X:1935 and make it retransmit it to Internet being acessible throught http://200.130.15.X:1935?

Did you try to redirect the HTTP to the internal one?

You need to setup port forwarding on your NAT/firewall. The procedure is dependent on your vendor, and is out of scope of this forum.

The two computers are in different places and networks.

I would like to start a ˜vlc stream server˜ on the computer that have external IP like 200.130.15.X using the port 1935.

The other computer doesn't have external IP and isnt connected to the same network. It would be like a "vlc client" that would connect to the vlc stream server.

The only connection between them is throught SSH.

This is the way I do it for my Foscam babycam using a CentOS minimal installation with vlc installed.

/usr/bin/vlc -I dummy "http://172.13.23.111:8080/videostream.c ... 32&rate=11" --no-sout-audio --sout '#standard{access=http{user=someusername,pwd=somepassword},mux=ogg,dst=0.0.0.0:8888}' &

I wrote a couple scripts to kick off a couple different versions of those strings (differing framerates on different ports) and tossed them into my rc.local file, which fires the feeds up on startup.

I then poked a hole in my firewall for the stream server on port 8888, using time-based access lists. So now any host from the outside running vlc can hit it with the following:
vlc http://someusername:somepassword@mydomain.com:8888

Family can now watch our baby on their iPads, Androids, and vlc media players. This has been bulletproof for well over a year running 3 different streams serving tens of simultaneous connections. CPU on the stream server is nill, since this is pretty much just network socket action.
