Hello:
EveryOne, Thanks for your help!
Now my problem is that: my client player and the stream server
are behind different NAT ,after client player connect the stream serve by
rtsp protocal,the stream serve begin send the video rtp packets,but the rtp
packets can not arrive to the client player. The cause maybe is that: the
rtp packets can not find the the client player client rtp port because the
Nat. I think if mapping all the udp port it is too trouble,The software vlc
can solve this problem,but I do not known how it do?
