Stream Forward

[karhuFI]

Hello,

I'm using VLC 0.9.9 on Windows Server, trying to forward rtp packet from a network (192.168.0.0/24) to another network (10.10.0.0/24).
I capture rtp packet with the following command line :

"c:\Program Files\VideoLAN\VLC\vlc.exe" udp://@10.10.10.100:1234.
Rtp packet seems to be reveive because when i look at statistics i can see there are input packet from the source.

but there are no rtp packets forwarded, using the following command line :
:sout=#duplicate{dst=rtp{dst=192.168.0.3,port=1234,port-audio=1234,port-video=1236}}

There are 2 networks card on my VLC's computer. one on 192.168.0.0/24 and the other on 10.10.0.0/24 network.

any ideas ?

Cheers,
Karhu

Any idea ?
I don't know what is wrong...maybe the command lines !?

[Rémi Denis-Courmont]

If the input is RTP then why the heck do you open it as a raw UDP stream? No wonder it's not working.

[karhuFI]

Yes, true true my mistake

Well now it's working to relay rtp packet ! Ok, it's almost working cause to relay rtp packets from one network to the other i need to call 2 instances of Vlc..
The first instance, which is listening on 192.168.0.0/24 network and forward the stream to 10.10.10.0/24 network and the other instance, listening on 10.10.10.0/24 and forward the stream to 192.168.0.0/24 network.. And when i call 2 instances of VLC, one of them is not working..I mean one of the following command is not working !! maybe cause i am calling simillar library !?
I need some help

Below are the 2 commands line !!

"c:\Program Files\VideoLAN\VLC\vlc.exe" -vvv rtp://@10.10.10.100:5678 :sout=#duplicate{dst=rtp{dst=192.168.0.3,port=1234,port-audio=1234,port-video=1236}} :sout-keep

"c:\Program Files\VideoLAN\VLC\vlc.exe" -vvv rtp://@192.168.0.100:1234 :sout=#duplicate{dst=rtp{dst=10.10.10.3,port=1234,port-audio=1234,port-video=1236}} :sout-keep

Thanks.

[karhuFI]

Other question, is it possible to listen on 2 inputs streams and relay it to 2 output Ips ?

[karhuFI]

Well i used :input-slave=rtp to listen for the other stream. But how to specify the good output for the input-slave stream !? is there any output-slave ??

[Rémi Denis-Courmont]

duplicate and select can specify which elemetary stream to send where. This is explained in the streaming howto.

Hi everybody,

I am able to catch rtp audio stream from sip phone, where audio is on 1234 port. With the following line everything
is fine and rtp packets are well relayed to 10.10.10.0/24 network.

"c:\Program Files\VideoLAN\VLC\vlc.exe" -vvv rtp://@192.168.0.100:1234 :sout=#duplicate{dst=rtp{dst=10.10.10.3,port=1234,port-audio=1234,port-video=1236}} :sout-keep

The idea is now to catch the video witch is send trough rtp on 1236 port but there is no rtp packets coming on vlc input. When i start wireshark i can
see the video is sent to 192.168.0.100:1236 with rtp protocol..so when i start vlc with :

"c:\Program Files\VideoLAN\VLC\vlc.exe" -vvv rtp://@192.168.0.100:1236 there is no input stream or whatever..
i'm a bit wondering what is wrong

below the log file and the command line for rtp video packets:
"c:\Program Files\VideoLAN\VLC\vlc.exe" -vvv rtp://@192.168.0.100:1236 :sout=#duplicate{dst=rtp{dst=10.10.10.3,port=5002,port-video=5004}} :sout-keep

Yes I have the same problem

in a SIP Call I received two UDP flow (Voice RTP) and Video (H.263). I can listen the audio stream in a UDP port. However I can't watch the Video.

Using wireshark I see the video packets.

What can I do? Thanks for your help!
