<div dir="ltr">Hi Experts, I have a doubt regarding this pipeline (udpsrc -> fakesink) # gst-launch-0.10 udpsrc port=5060 ! rtppcmadepay ! alawdec ! fakesink Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: GstSystemClock On launching it from gst-launch, it stops at last statement above. I think, it is because of lack of data on port 5060. Is it correct understanding ? Similiarly, when I try to set the pipeline to PLAYING state from code, it returns GST_STATE_CHANGE_ASYNC and on trying to get again the state it blocks indefinitely. Here is the code... state_return = gst_element_set_state (mPlayBin, GST_STATE_PLAYING); GST_PLAYER_DEBUG("state_return = %d\n", state_return); if (state_return == GST_STATE_CHANGE_FAILURE) { GST_PLAYER_ERROR ("Fail to set pipeline to PLAYING\n"); goto EXIT; } else if (state_return == GST_STATE_CHANGE_ASYNC) { GstState state; // wait for state change complete GST_PLAYER_DEBUG("Wait for pipeline's state change to PLAYING...\n"); state_return = gst_element_get_state (mPlayBin, &state, NULL, GST_CLOCK_TIME_NONE); GST_PLAYER_DEBUG("Pipeline's state change to PLAYING\n"); if (state_return != GST_STATE_CHANGE_SUCCESS || state != GST_STATE_PLAYING ) { GST_PLAYER_ERROR ("Fail to set pipeline to PLAYING\n"); goto EXIT; } } Please help.
