I'd prefer option 2 :-)
Regarding to 1 and 3, sometimes a user task may blocked there waiting for a
signal(from user). If GstVideoDeocder or GstPad force to gst_pad_stop_task,
they need make a hook to notify user to wakeup the task first then stop the
task. and if there's hook to notify, there's no need for GstVideoDecoder of
GstPad stop the task. so I prefer option 2 to make GstVideoDocoder hook stop
before parent->GstElement::change_stat().
