#
prooblem with gst-rtsp-server tcp connection ,no pbm in udp
#
-----------------------------------------------------------------
#
 
#
I am using gst-rtsp-server as streaming server and Realplayer as streaming clinet.It is in wan so that i need tcp connectionn always for better clarity.In the client side i setted up always use tcp as protocol and specify timeout of 20000 milleseconds as timeout.But didnt get working.Follwoing is the server side(gst-rtsp-server) log message of network traffic i got.I dont know what is the problem happening here!!!!!If it changed to udp then it worked.

But if the streaming server is Darwin,both quicktime and realplayer are working.But gst-rtsp-server is working only with vlc.In case of vlc,i used vlc --rtsp-tcp rtsp://10.0.0.145:8554/test.mp4.And it is in wan.it worked.




following is the log messages of server side when the client is realplayer.
