[gst-devel] No notify signal from queue element

[Learner]

Hi Stefan,

  The Queue properties which I was referring to are 
READ ONLY properties, hence a g_object_set() will 
not work.
 
(1)current-level-buffers   
(2)current-level-bytes  
(3)current-level-time

  These properties report the current buffer 
level in the queue, and hence are altered
by the queue only. 

  As per the documentation, the changes can be 
tracked by a notify , but that does not work.

  I have tried using a fakesrc with the queue 
and fakesink in a sample application, 
but the notify did not trigger.

  IMHO a g_object_notify call needs to be made 
in gstqueue.c in places where the below 
fields are updated.

queue->cur_level.buffers 
queue->cur_level.bytes 
queue->cur_level.time 

Thanks !
