Issue in vorbisdec

[W.A. Garrett Weaver]

Thank you for getting back to me. What I was trying to do was run this
audio UDP transmission script using the vorbis codec:

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

This worked fine. The receiver script did not.

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

Which reported that it "Could not decode stream" and "Could not switch code
books"

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".

However, putting it between single quotes, which is something that I didn't
think to do: worked. Thank you.
