Hi, I am working with RTSP streaming using darwin streaming server. . audio and video streaming is working fine with the TCP protocol. I am tryng to play the audio using  udp protocol. audio is just playing for aroun 5 seconds..after that no audio. I tried with the gst-launch and separate application.. both are giving same result... This test vector consists of both audio as well as video.. can any body suggest me to find out the bug.. I am giving below the gst-launch command gst-launch rtspsrc  location=rtspu://196.168.1.110/sample_50kbit.3gp !  rtpamrdepay  !  amrnbdec !  osssink advance thanks.. Trimurthulu
