Facing problems during WMP RTSP Streaming

[venu]

Hi everyone,
We are developing an RTSP Server to stream mpeg4 and h264 video data muxed in asf and receive them on Winows Media Player 11. The muxing is done by gstreamer's ffmpeg muxer element.

During the session establishment the following RTSP messages are exchanged between the server and the client:

After these exchanges our Gstreamer pipeline starts streaming RTP data to the client port number 1848. We are confirming this after capturing the packets using Wireshark .But the WMP isnt' playing back the data. The statistics in WMP show the "packets received" as 0.

We have tried all the possible means but still in vain. Please send me some advises so that this issue can be resolved asap.

Thanks in Advance

WMP mentions a particular port number during SETUP to where the data has to be streamed during RTSP Session establishment. But when we stream RTP data to that particular port no WMP does not receive those streams as is shown in the statistics.

If there is something wrong in the data we send does WMP discard the data? We aint getting any error messages regarding the data that is being streamed.

Why is WMP showing "packets received" as 0 though data is sent to that port itself.

Please help
