Help for how to enable realvideo in gstreamer in Android platform

[Bonder Wu]

Hi, All

    I am a newbie in gstreamer. I have integrated gstreamer in Android
platform. Now I want to enable realvideo in gstreamer in Android
platform, I do the following things:
1. Enable gst-plugins-ugly/gst/readmedia/ for demuxer
2. Enable gst-plugins-bad/gst/real/ for codec

But it can not work. the log says that:
10-25 19:00:29.476 D/GstPlayer( 1783): [1792], DEBUG
GstPlayerPipeline.cpp:1434, prepareAsync(): Wait for pipeline's state
