Troule Shooting：openRTSP無法接收internet packet

Streaming over TCP

By default, incoming data (RTP and RTCP packets) are streamed using UDP. If, however, you have a broken Internet connection that (for whatever reason) does not pass incoming UDP packets, then you can ask that the incoming data be streamed over TCP instead. (It will use the same TCP connection as RTSP.)

To do this, add the option

    -rtsp-stream-over-tcp 

to MPlayer. (Note that TCP streaming can be used only with "rtsp://" URLs; it can't be used with sessions that are specified using a SDP file.)
