pipeline does not re-enter playing after some play-pause cycle

[alessand01]

Hi all,
I'm working on a gstreamer application written in c++. I have two different pipelines streaming two video sources through two UDPsink. If I run the application the streaming works without problems for at least 1 hour. But if try to pause and play the two videos, after a while on of the two pipeline does not enter the PLAYING state and the 'gst_element_get_state' (called after 'gst_element_set_state') returns the GST_STATE_CHANGE_ASYNC value and it mantains the PAUSED state.
The PLAY-PAUSE switch is made internally the application, using the 'gst_element_set_state' function, once with GST_STATE_PAUSE and one with GST_STATE_PLAYING.

I'm working on this problem during the last two days without any progress... Please someone help me!

Thanks!

EDIT:
I forgot to say that after every PAUSED, before set the PLAYING, I change the udpsink port value.
And then.. it works for about 10 cycle, and after the PLAYING can't be entered!

Hi,

Can you send some debug logs? You can run your program with the
following environment variables:

GST_DEBUG="*:6" GST_DEBUG_NO_COLOR=1

Redirect error output to a file, compress that file and send it.

Thanks!

Hi,

Are you waiting for GST_MESSAGE_ASYNC_DONE event on a bus after pause/play  to continue doing anything else?

Thank you Vivia and Mikl,
I'm not waiting for the the GST_MESSAGE_ASYNC_DONE event, and as a newbie I don't know how to wait for that. I will do some researches, and if I can't resolve the issue I will come back here to ask help (posting the debug output as Vivia has suggested!)

Thank you guys!!
