Unable to change state GST_STATE_PLAYING

[amitchawla]

Hi,

I am using the following pipeline, where I am reading from the network

"tcpserversrc blocksize=4194304 host=192.168.100.58 port=3000 ! 
 decodebin async-handling=true name=demux ! 
 autoaudiosink async-handling=true demux. ! 
 imxeglvivsink async=false"

I need to restart the pipeline, when new data is coming through the network. 
The initial state is that, the above pipeline is playing normally -- the
pipeline is in GST_STATE_PLAYING.

then, I do the following operations : -

     set_pipeline_state(GST_STATE_PAUSED);
     set_pipeline_state(GST_STATE_READY);
     set_pipeline_state(GST_STATE_NULL);
     --- enable_fresh_data_from_network --- ;
     set_pipeline_state(GST_STATE_READY) ;
     set_pipeline_state(GST_STATE_PAUSED) ;
     set_pipeline_state(GST_STATE_PLAYING) ;

It goes to GST_STATE_NULL normally.
But I notice that the pipeline state never changes to GST_STATE_PLAYING from
GST_STATE_PAUSED. It is stuck at GST_STATE_PAUSED. 
The status of the operation returns  GST_STATE_CHANGE_ASYNC always. I have
used gst_element_get_state but it always returns GST_STATE_CHANGE_ASYNC.

I enabled GST_STATES debug output. The log output shows all the elements
moving to GST_STATE_PLAYING eventually but the, the stream doesn't start
playing. 

But when I tried to grab the bus messages, I noticed that I don't get state
change message to PLAYING on the bus, I only get state change message upto
PAUSED.  
 
I would be very thankful, if anyone could provide some explanation. 

regards
Amit
