function call blocked

Hi Experts,

I have written a pipeline for udpsrc -> fakesink. udpsrc port=9000 ! rtppcmadepay ! alawdec ! audioconvert ! audioresample ! fakesink

But after setting the pipeline to PLAYING state, I get STATE_CHANGE_ASYNC then when I try to get the state using, gst_element_get_state, It gets blocked forever.

Any idea ?

Kind Regards

A get_state() will block for as long as all sinks have not received any
data. Are you sure there is data being sent on the both udpsrc?

Re: function call blocked

Yes. Data is there. In fact, I could hear the data when I put real sink. But the calls remains blocked forever....
