RealDataTransport (RDT)

The Real Data Transport protocol is used by realPlayer and other players to transport media samples. RDT frames can either be interleaved within the controlling RTSP connection or can be setup over a separate UDP stream.

Protocol dependencies


The RDT dissector is very nearly complete.

Preference Settings

Display Filter

A complete list of RDT display filter fields can be found in the display filter reference

Capture Filter

You cannot directly filter RDT protocols while capturing. However, if you know the RTSP port used (tcp port 554 by default), you can filter on that (this will work at least for the case where RDT frames are interleaved within the RTSP connection)
