First of all, please use a recent version of GStreamer. What you use
there is 0.10 and not maintained anymore since almost 3 years. You can
get the latest binaries for Android here:
http://gstreamer.freedesktop.org/data/pkg/android/1.4.5/

Then, the best pipeline for playing RTSP streams is
  playbin uri=rtsp://....

It will select the best available decoders and other elements required
to display your stream and output any audio streams.


But in your pipeline above the problem is that you use a tee element.
Instead just link the audio and video branches directly to rtspsrc.
rtspsrc is adding two source pads to itself, one for audio and one for
video.

Also you don't have to add a jitterbuffer like that. rtspsrc already
contains it internally and adding a second one won't make things work
better :)
