Try to find the reason why it causes artefacts. Are too many packets
getting lost?

You should also use rtpbin for RTP to be actually useful, and might also
want to use gst-rtsp-server for simplicity if you can use RTSP.

For rtpbin usage see gst-plugins-good/tests/examples/rtp. There are some
shell scripts that show how it can be used.


Apart from that you should consider to upgrade to GStreamer 1.x, e.g. by
using the binaries provided here by the GStreamer project:
http://gstreamer.freedesktop.org/data/pkg/android/1.2.2/
