For a project that I have to submit, I have to perform a streaming
among 2 computers (with RTP protocol) using VLC media player, and then
capture the packets with Wireshark in order to evaluate eventual packet
losses. I have got two questions:
As a first step I tried to use the same computer both for sending
and for receiving the stream: I opened the RTP network stream on
another window of VLC media player and the video is effectively shown.
However Wireshark captured the transmitted/received packets, but it
shows them in the log file as a list of UDP packets (layer 4 instead of
layer 7) and I can’t have access to any sequence number and,
consequently, I can’t find out anything about eventual packet losses.
How can I set up Wireshark in order to have displayed the protocol used
at layer 7 instead or 4? Or anyway, how can I have displayed the RTP
sequence of packets instead of the UDP ones?
Alternatively do anyone know any ACTIVE source of online streaming
that broadcasts using RTP protocol and that would allow me to perform a
capture of RTP packets? It would be ok also with RTSP: in other words I
need to obtain a Wireshark log file with some consecutive sequence
numbers in order to evaluate the packet losses
Thanks a lot for your answers!
