Blocked when setting state to PLAYING

[deeps8us]

I have a gstreamer code with functions such as load_pipeline, play, stop and seek.
Using a testapp, in while (1) loop, I monitor for user input and call load / play / stop accordingly.
Since I have a while loop in testapp, I dont have g_main_loop running in my gstreamer code.

I can successfully do load and play. Problem is: once playing, it will no longer monitor for any other key input. It is like it went to blocked state. (Just like g_main_loop is running)
My play function is only having the line gst_element_set_state(play, GST_STATE_PLAYING);
What could be the issue.

Hi

Signals, messages and many other things require the GMainLoop running to work. If you have a while(1) you may try adding g_main_context_iteration() before completing a loop iteration. This will check for pending events. See more at:
