Wireshark · Ethereal-dev: Re: [Ethereal-dev] Streamed MPEG2 TS dissector

[Alex <home@xxxxxxxxxxxxxxx>]

Hi Alejandro,

In the context of voice/video over IP, you're right, the payload is 
negotiated.

Initially I am interested in purely video streaming applications, as 
VideoLAN's vlc media player, that just streams RTP with MPEG2 TS payload 
without previous negotiation. Another vlc client listens for the stream 
at a mutually agreed port.

As a starting point, this setup is easier to undertake.

Thanks a lot for your comments,
Alex
