Get the clock pointer using the io_changed stream event. and update the clock before triggering the process The clock needs to be updated in the data loop thread and before triggering the process so move the calls to `pw_stream_trigger_process` from gstreamer thread context into the data loop thread context by invoking a callback and update the clock inside the data loop callback before the trigger
