[vlc-devel] Facing problems during WMP RTSP Streaming

Wed Dec 3 06:25:59 CET 2008

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
