Once again Here i am not suspecting the gstreamer.. Please dont think this bug
from gstreamer point of view .. but i need from playbin point of view what it
requires .. or else please suggest me for any reference ... 

And one more thing here i am changed my filter architecture.. Previously i am
using only one filter for doing all(Demuxing,Decoding,Rendering). But now i
have both AudioSink and Video Sink elements in Chain. Here sink elements i am
added for Gstreamer supporting...
So Now I have 3follwing Filters
1. MyDemuxer      Codec/Demuxer With Rank 300
2. MyAudioSink    Sink/Audio    with Rank 300
3. MyVideoSink    Sink/Video    with Rank 300

with this filters Follwing chain working fine.

gst-launch-0.10 filesrc location=/home/sample_mpeg4.mp4 ! MyDemuxer name=demux
{demux.audio_00 ! MyAudioSink }  {demux.video_00 ! MyVideoSink }

where as same thing is not fine with Playbin...????

My other Observations:

When i am testing my chain with -m option i mean (gst-launch-0.10 -m filesrc..)
& (gst-launch-0.10 -m Playbin....)
here i am giving debug log:

1.gst-launch-0.10 -m filesrc
