Another thing I notice is that you are using "video/x-raw-yuv", that
type was used in 0.10 and no longer exist in 1.0+. Should be video/x-
raw,... Are you trying to use obsolete 0.10 rather then 1.0+ (e.g.
1.10.3) ?

And another error you did, "rtpvp8vpay" is named "rtpvp8pay". You have
an extra v in there.

Final note, Opus is more common then vorbis these days, but both should
work.

Actually, I meant to set this to it's minimum, try deadline=1. 0 is the
default, it means no deadline, and is really slow.

Have you enabled debug traces ? E.g. for warning and error, set the
environment GST_DEBUG=3.

Nicolas

p.s. A working 1.0 example using test-launch:

GST_DEBUG=2 ./test-launch \
  "v4l2src device=/dev/video0 \
     ! videoconvert ! vp8enc deadline=1 end-usage=cbr \
     ! rtpvp8pay pt=96  name=pay0 \
   pulsesrc ! audioresample ! audioconvert ! vorbisenc \
     ! rtpvorbispay pt=0 name=pay1"
