[gst-devel] Going to PAUSE for a task-based source element: dead lock

I am writing a source element reading network
packets. It spawns a GstTask to create
buffers and push them to source pads.
A problem arise when I try to go to the PAUSE
state. In the change_state() function, I ask
the task to stop processing packets, and then
wait for its acknowledgement. The task
continues its work but is blocked when
I guess that gst_pad_push() blocks as soon as
the parent element goes to PAUSE state... But
this does not work for me as I have to handle
an asynchronous control stream to request to
actual network source to stop sending
packets. Even then, there may be a few
pending packets that I need to process before
actually going to PAUSE.
I would like to know if gstreamer is able to
handle such a situation, or if I am just try
to do something that is not allowed by
Thank very much you for your help!
