Thanks for the hint! It turned out (thanks to wesley) that the reason
was the missing audioresample plugin (before directsoundsink). I think
dropped packets shouldn't be a problem in my scenario (GBit switch and
just 2 PCs connected). But still i will keep that MTU-related problem in

Betreff: Re: Sending and receiving RTP audio
I think this is related to the data being lost during transmission, as I
faced similar issue in one project.
I fixed that by configuring rtppay in such a way that mtu is fixed and
of some 1400 bytes.
Not sure if you have similar issue.

I use OSSBuild with Gstreamer 10.7 (Beta4) on Win7 to transmit
test signal via UDP/Multicast. It works, but the sound is awful
gst-launch -v gstrtpbin name=rtpbin audiotestsrc ! audioconvert
rtpL16pay ! rtpbin.send_rtp_sink_1 rtpbin.send_rtp_src_1 !
port=5002 host=18.104.22.168 rtpbin.send_rtcp_src_1 ! udpsink
host=22.214.171.124 sync=false async=false udpsrc port=5007 !
gst-launch -v gstrtpbin name=rtpbin udpsrc
edia=(string)audio,channels=(int)1 ! rtpbin.recv_rtp_sink_0
rtpL16depay ! audioconvert ! directsoundsink udpsrc
uri=udp://126.96.36.199:5003 ! rtpbin.recv_rtcp_sink_0
rtpbin.send_rtcp_src_0 ! udpsink port=5007 host=188.8.131.52
I think it must have something to do with the 'caps' or a buffer
problem. Any ideas?
