Hello All,
This is kishore from INDIA. we are developing an MPEG2 Streaming server on windows. Actually my problem is, After sending the RTSP SETUP Response to client ( VLC Player ) i am not getting any further RTSP Request from client. And also the existing connection has been forcibly closed by the client. I am describing the total Session Details below. please see, and kindly tell me what exactly the problem is. And one more problem is the connection between my Server and Client has been forcibly closed by the Client.

"livedotcom error: PLAY failed No RTSP session is currently in progress" suggests that its the problem of liblivemedia library that is the live555 libraries that VLC use for rtsp streaming. One possibility would be to check the live555.cpp file in modules/demux folder which contains the Play method and trace the error. Other possible thing would be to trace the error in the live555 library code.
