The classes are how they are structured. I am trying to send eos through
avimux but it freezes there. If I  send through srcPipeline it's successful.
I have look through the code but haven't come up with an answer. what i want
to do is send eos through unlink the  queue3,queue4,avimux and appsink. then
i will relink them back. I have done this before but don't understand why it
doesn't want to send through avimux. anyone know? I also have faksinks
connected to the vtee and atee for continuous play.

videoRecClass.cpp
---------------------
GstElement* srcPipeline;
deletepipeline();
linkpipeline();
setuppipeline();
unlinkpipeline();

PipelineClass.cpp
---------------------
_videoRecClass;

sendEosThroughAviMux(PipelineClass* pipe)
{
      GstElement* avimux =
gst_bin_get_by_name(GST_BIN(pipe->_videoRecClass.srcPipeline),"avimux");
      if(!gst_element_send_event(avimux,gst_event_new_eos()))
	{
                ImmediateLoopQuit();
	}
}
