pad is flushing?

This post was updated on .
*pipeline*
------------------------------------------------------------------------------
                                                                      ----src_1
       ------ rtph264depay --- h264parse ---- vtee ----- src_2
rtspsrc
       ------ rtpmp4gdepay --- aacparse ----- atee ----- src_2
                                                                     ------src_1

*src_1*
----------
vtee ---- queue ----
                   avimux1 ----- appsink1
atee ---- queue ----

*src_2*
----------
vtee ------ queue ----
                       avimux2 ----- appsink2
atee ------ queue ----

I have the following pipeline that use in c++ that I switch between each
branch on the tees. I will eos on one branch and start recording on the
other.

*Stop Branch*
---------------
Block teePads,Eos through queues,unlink queues from tee, null each
element,unblock the tee,release pads
*
Start Branch*
---------------
request pads on tees,link pads to queues, play each element

*Problem*
----------------
for some reason when I go to start the branch after it was null last time I
stopped it, the last flow return was flushing. why would that be? It doesn't
happen every time I go to start a new one it just happens to occur the one
time. The branch doesn't start correctly so I have to stop it. If i try to
stop it it can't block the tee that is flushing. What would be the reason?
any ideas?

I'm not for sure but it might have worked to re-initiate the tee pads if they
are flushing.

GstElement* atee = gst_bin_get_by_name(GST_BIN(pipeline),"audiotee");
GstEvent* FlushStopEvent = gst_event_new_flush_stop(FALSE);
GstPad* pad = gst_element_get_static_pad(atee, teePadName.c_str());
if (gst_pad_get_last_flow_return(pad) == GST_FLOW_FLUSHING)
      gst_element_send_event(atee, FlushStopEvent);

Well I guess this didn't work at all. The rest of the pads beyond the tee are
fine. for some reason at the tee pad src_2 or src_1 are flushing even though
I released the pads from the tee. It just happens randomly.

Re: pad is flushing?

killerrats
if you remove the probe then release the pad from the tee could the flushing
affect right when I remove the probe? So If stop the flushing on each
element before removing the probe could that be the answer to my problem?

for Example:

tee ---- queue
       <--- flushing

tee ---- queue
       <--- flushing
