Thank you for getting back to me. What I was trying to do was run this audio UDP transmission script using the vorbis codec:<br><br>gst-launch-0.10 pulsesrc device=alsa_input.usb-046d_0809_B11D4DC2-02-U0x46d0x809.analog-mono ! audioconvert ! vorbisenc ! rtpvorbispay ! udpsink host=224.1.1.1 port=3000 auto-multicast=true<br> <br>This worked fine. The receiver script did not. <br><br>gst-launch-0.10 udpsrc multicast-group=224.1.1.1 auto-multicast=true port=3000 caps=application/x-rtp ! gstrtpjitterbuffer drop-on-latency=false latency=100 ! rtpvorbisdepay ! vorbisdec ! pulsesink<br> <br>Which reported that it "Could not decode stream" and "Could not switch code books"<br><br>I found, from other resources, that adding '-v' to the transmission script would reveal the correct, but lengthy, caps output but plugging that directly into the receive script did not work saying that erroneous pipeline: could not set property "caps" in element "udpsrc0".<br> <br>However, putting it between single quotes, which is something that I didn't think to do: worked. Thank you. <br><br><div class="gmail_quote">On Sat, Mar 24, 2012 at 5:01 AM, Tim-Philipp Müller <span dir="ltr"><<a href="mailto:t.i.m@zen.co.uk">t.i.m@zen.co.uk</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="im">On Sat, 2012-03-24 at 03:46 -0700, garrett wrote:<br> <br> > Hello, I have come across the same issue as the OP of this message.
