How to stream video from webcam using Gstreamer?

How to stream video(and if it possible audio too) from webcam using Gstreamer? I already tried to stream video from source, but I can't stream video from webcam on Windows. How I can do this?

Client: 

    VIDEO_CAPS="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H263-1998"
DEST=localhost
VIDEO_DEC="rtph263pdepay ! avdec_h263"
VIDEO_SINK="videoconvert ! autovideosink"
LATENCY=100
gst-launch -v gstrtpbin name=rtpbin latency=$LATENCY                                    \
           udpsrc caps=$VIDEO_CAPS port=5000 ! rtpbin.recv_rtp_sink_0                   \
             rtpbin. ! $VIDEO_DEC ! $VIDEO_SINK                                     \
           udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0                                   \
           rtpbin.send_rtcp_src_0 ! udpsink host=$DEST port=5005 sync=false async=false

Server:

DEST=127.0.0.1
VOFFSET=0
AOFFSET=0
VELEM="ksvideosrc is-live=1"
VCAPS="video/x-raw,width=352,height=288,framerate=15/1"
VSOURCE="$VELEM ! $VCAPS"
VENC="avenc_h263p ! rtph263ppay"
VRTPSINK="udpsink port=5000 host=$DEST ts-offset=$VOFFSET name=vrtpsink"
VRTCPSINK="udpsink port=5001 host=$DEST sync=false async=false name=vrtcpsink"
VRTCPSRC="udpsrc port=5005 name=vrtpsrc"
gst-launch gstrtpbin name=rtpbin
            $VSOURCE ! $VENC ! rtpbin.send_rtp_sink_2
          rtpbin.send_rtp_src_2 ! $VRTPSINK 
              rtpbin.send_rtcp_src_2 ! $VRTCPSINK
            $VRTCPSRC ! rtpbin.recv_rtcp_sink_2

You will have to use GStreamer 1.3.90 or newer and the ksvideosrc element that is available only since that version.

And then you can stream it just like any other input... the details depend on what codecs, container format, streaming protocol and network protocol you want to use. The same goes for audio, that works basically exactly the same as video.

http://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/tests/examples/rtp here you can find some examples that use RTP for streaming. Server side and client side examples, audio-only, video-only or both. And also streaming from real audio/video capture sources (for Linux though, but on Windows it works exactly the same... just with the Windows specific elements for that).
