There is a race with playbin2, it works sometimes and sometimes not.

I would like to put the bug in another way. 
If you try to run the attached test_5sec_audio_delay.flv stream, using 
gst-launch-0.10 -v filesrc location=test_5sec_audio_delay.flv ! decodebin2 !
fakesink, 
you will see that the pipeline will hang since its not able to preroll. It
seems that there is one empty queue and one full queue (plz refer the attached
logs). Since the empty queue condition is not being checked, the full queue
waits for more space to happen, but neither its size is increased nor the data
is consumed since other queue is still empty. This I cross verified by changing
the  max-size-time property of multiqueue from 5 sec to 10 secs in decodebin2.

Also you can check test_4.9sec_audio_delay.flv which works properly with above
pipeline.


A thought: In case of mp3 the audio queue can easily get empty by consuming all
data without generating any sample, and hence not prerolling.
