[gst-devel] About RTSP server--streaming mp3 files

Mon Mar 16 11:15:27 CET 2009

Today , I use gstreamer as a streamer receiver.
My pipeline is like this : 

gst-launch -v  rtspsrc location=rtsp://192.168.1.45:1554/test  latency=10  !
rtpmpadepay ! fakesink

However , I still can not receive the stream. The message is following:
