If I were you I would try this pipeline (please note the queues, that
should decouple the elements - use the queues luke!):
gst-launch-0.10 v4lsrc device=/dev/video0 ! "video/x-raw-yuv",width=320,height=240 !
ffmpegcolorspace ! theoraenc bitrate=80 ! queue ! mux.
alsasrc device="maestro3" ! audioconvert ! vorbisenc ! queue ! mux.
oggmux name=mux ! filesink location=test.ogm
I have no *cast running and won't install it, but replacing the filesink
with shout2send. You will also have to adjust the alsasrc line, but this
gives me a ogg container with muxed vorbis sound and theora video.
HTH
