Hi all

I need to send RTP/UDP/IP(v4 and v6) traffic continuously through vlc. Currently it is sending UDP/IP traffic (saw in wireshark capture) most of the time and only some times it is sending RTP traffic. I cannot find out the exact scenario of sending RTP packets continuously

I selected RTP packets in the vlc player, but still it sends udp traffic.

Can any one Pls tell me..

Thanks in advance

It sends RTP when it's configured to send RTP.

Hi Remi,

I configured vlc to send RTP packets, but some times it is sending only UDP packets. I am using version 1.0.0.

It is not continuously sending RTP packets. I have to start and stop the both vlc's and after some 5 tries only it is sending RTP packets (thro' wireshark i saw the packets)

Senthil..

Maybe wireshark does not detect RTP properly...

Wireshark is pretty dumb by default, so yeah, it won't detect the RTP properly. Try running wireshark or tshark with -d udp.port=1234,rtp (obviously replace the port you are sending traffic to) - this tells wireshark to decode the traffic to udp port 1234 as RTP, and you might find that all the packets are actually RTP when you do this.

Also if you haven't enabled rtcp-mux then your client will sent RTCP packets as well, these might show up as UDP if you haven't set up your sniffer to decode the traffic as RTCP.

Edit: Also if you're unaware, RTP is a UDP protocol.

Hi all!

I have the same problem. I am working with the VLC, streaming a video using RTP. i have captured the packets in the client with wireshark but i have only UDP packets, not RTP packets. i need to make a stream analysis but i cannot without RTP packets... ¿How can I configure wireshark to have RTP packets?

Thanks in advance!
